LEVEMIR® (insulin detemir [rDNA origin] injection) is a sterile solution of insulin detemir for use as a subcutaneous injection. Insulin detemir is a long-acting (up to 24-hour duration of action) recombinant human insulin analog. LEVEMIR® is produced by a process that includes expression of recombinant DNA in Saccharomyces cerevisiae followed by chemical modification.
Insulin detemir differs from human insulin in that the amino acid threonine in position B30 has been omitted, and a C14 fatty acid chain has been attached to the amino acid B29. Insulin detemir has a molecular formula of C267H402O76N64S6 and a molecular weight of 5916.9. It has the following structure:
Figure 1: Structural Formula of insulin detemir
LEVEMIR® is a clear, colorless, aqueous, neutral sterile solution. Each milliliter of LEVEMIR® contains 100 units (14.2 mg/mL) insulin detemir, 65.4 mcg zinc, 2.06 mg m-cresol, 16.0 mg glycerol, 1.80 mg phenol, 0.89 mg disodium phosphate dihydrate, 1.17 mg sodium chloride, and water for injection. Hydrochloric acid and/or sodium hydroxide may be added to adjust pH. LEVEMIR® has a pH of approximately 7.4.

LEVEMIR® is indicated to improve glycemic control in adults and children with diabetes mellitus.
Important Limitations of Use
LEVEMIR® is not recommended for the treatment of diabetic ketoacidosis. Intravenous rapid-acting or short-acting insulin is the preferred treatment for this condition.
DOSAGE AND ADMINISTRATION
LEVEMIR® is a recombinant human insulin analog for once- or twice-daily subcutaneous administration.
Patients treated with LEVEMIR® once-daily should administer the dose with the evening meal or at bedtime.
Patients who require twice-daily dosing can administer the evening dose with the evening meal, at bedtime, or 12 hours after the morning dose.
The dose of LEVEMIR® must be individualized based on clinical response. Blood glucose monitoring is essential in all patients receiving insulin therapy.
Patients adjusting the amount or timing of dosing with LEVEMIR® should only do so under medical supervision with appropriate glucose monitoring [see WARNINGS AND PRECAUTIONS].
In patients with type 1 diabetes, LEVEMIR® must be used in a regimen with rapid-acting or short-acting insulin.
LEVEMIR® can be injected subcutaneously in the thigh, abdominal wall, or upper arm. As with all insulins, the rate of absorption, and consequently the onset and duration of action, may be affected by exercise and other variables, such as stress, intercurrent illness, or changes in co-administered medications or meal patterns.
When using LEVEMIR® with a glucagon-like peptide (GLP)-1 receptor agonist, administer as separate injections. Never mix. It is acceptable to inject LEVEMIR® and a GLP-1 receptor agonist in the same body region but the injections should not be adjacent to each other.
Initiation Of LEVEMIR® Therapy
The recommended starting dose of LEVEMIR® in patients with type 1 diabetes should be approximately one-third of the total daily insulin requirements. Rapid-acting or short-acting, pre-meal insulin should be used to satisfy the remainder of the daily insulin requirements.
The recommended starting dose of LEVEMIR® in patients with type 2 diabetes inadequately controlled on oral antidiabetic medications is 10 Units (or 0.1-0.2 Units/kg) given once daily in the evening or divided into a twice daily regimen.
The recommended starting dose of LEVEMIR® in patients with type 2 diabetes inadequately controlled on a GLP-1 receptor agonist is 10 Units given once daily in the evening.
LEVEMIR® doses should subsequently be adjusted based on blood glucose measurements. The dosages of LEVEMIR® should be individualized under the supervision of a healthcare provider.
Converting To LEVEMIR® From Other Insulin Therapies
If converting from insulin glargine to LEVEMIR®, the change can be done on a unit-to-unit basis.
If converting from NPH insulin, the change can be done on a unit-to-unit basis. However, some patients with type 2 diabetes may require more LEVEMIR® than NPH insulin, as observed in one trial [see Clinical Studies].
As with all insulins, close glucose monitoring is recommended during the transition and in the initial weeks thereafter. Doses and timing of concurrent rapid-acting or short-acting insulins or other concomitant antidiabetic treatment may need to be adjusted.
Dosage Forms And Strengths
LEVEMIR® solution for injection 100 Unit per mL is available as:
- 3 mL LEVEMIR® FlexTouch®
- 10 mL vial
Storage And Handling
LEVEMIR® is available in the following package sizes: each presentation containing 100 Units of insulin detemir per mL (U-100).
3 mL LEVEMIR® FlexTouch® NDC 0169-6438-10 10 mL vial NDC 0169-3687-12
FlexTouch® can be used with NovoFine® or NovoTwist® disposable needles. Each FlexTouch® is for use by a single patient. LEVEMIR® FlexTouch® must never be shared between patients, even if the needle is changed.
Unused (unopened) LEVEMIR® should be stored in the refrigerator between 2° and 8°C (36° to 46°F). Do not store in the freezer or directly adjacent to the refrigerator cooling element. Do not freeze. Do not use LEVEMIR® if it has been frozen.
Unused (unopened) LEVEMIR® can be kept until the expiration date printed on the label if it is stored in a refrigerator. Keep unused LEVEMIR® in the carton so that it stays clean and protected from light.
If refrigeration is not possible, unused (unopened) LEVEMIR® can be kept unrefrigerated at room temperature, below 30°C (86°F) as long as it is kept as cool as possible and away from direct heat and light. Unrefrigerated LEVEMIR® should be discarded 42 days after it is first kept out of the refrigerator, even if the FlexTouch® or vial still contains insulin.
After initial use, vials should be stored in a refrigerator, never in a freezer. If refrigeration is not possible, the in-use vial can be kept unrefrigerated at room temperature, below 30°C (86°F) as long as it is kept as cool as possible and away from direct heat and light. Refrigerated LEVEMIR® vials should be discarded 42 days after initial use. Unrefrigerated LEVEMIR® vials should be discarded 42 days after they are first kept out of the refrigerator.
After initial use, the LEVEMIR® FlexTouch® must NOT be stored in a refrigerator and must NOT be stored with the needle in place. Keep the opened (in use) LEVEMIR® FlexTouch® away from direct heat and light at room temperature, below 30°C (86°F). Unrefrigerated LEVEMIR® FlexTouch® should be discarded 42 days after they are first kept out of the refrigerator.
Always remove the needle after each injection and store the LEVEMIR® FlexTouch® without a needle attached. This prevents contamination and/or infection, or leakage of insulin, and will ensure accurate dosing. Always use a new needle for each injection to prevent contamination.
The storage conditions are summarized in Table 13:

The following adverse reactions are discussed elsewhere:
- Hypoglycemia [see WARNINGS AND PRECAUTIONS]
- Hypersensitivity and allergic reactions [see WARNINGS AND PRECAUTIONS]
Clinical Trial Experience
Because clinical trials are conducted under widely varying designs, the adverse reaction rates reported in one clinical trial may not be easily compared to those rates reported in another clinical trial, and may not reflect the rates actually observed in clinical practice.
The frequencies of adverse reactions (excluding hypoglycemia) reported during LEVEMIR® clinical trials in patients with type 1 diabetes mellitus and type 2 diabetes mellitus are listed in Tables 1-4 below. See Tables 5 and 6 for the hypoglycemia findings.
In the LEVEMIR® add-on to liraglutide+metformin trial, all patients received liraglutide 1.8 mg + metformin during a 12-week run-in period. During the run-in period, 167 patients (17% of enrolled total) withdrew from the trial: 76 (46% of withdrawals) of these patients doing so because of gastrointestinal adverse reactions and 15 (9% of withdrawals) doing so due to other adverse events. Only those patients who completed the run-in period with inadequate glycemic control were randomized to 26 weeks of add-on therapy with LEVEMIR® or continued, unchanged treatment with liraglutide 1.8 mg + metformin. During this randomized 26-week period, diarrhea was the only adverse reaction reported in ≥ 5% of patients treated with liraglutide 1.8 mg + metformin (11.7%) and greater than in patients treated with liraglutide 1.8 mg and metformin alone (6.9%).
In two pooled trials, a total of 1155 adults with type 1 diabetes were exposed to individualized doses of LEVEMIR® (n=767) or NPH (n=388). The mean duration of exposure to LEVEMIR® was 153 days, and the total exposure to LEVEMIR® was 321 patient-years. The most common adverse reactions are summarized in Table 1.

A randomized, open-label, controlled clinical trial has been conducted in pregnant women with type 1 diabetes. [see Use in Specific Populations]
Hypoglycemia is the most commonly observed adverse reaction in patients using insulin, including LEVEMIR® [see WARNINGS AND PRECAUTIONS].
Tables 5 and 6 summarize the incidence of severe and non-severe hypoglycemia in the LEVEMIR® clinical trials.
For the adult trials and one of the pediatric trials (Study D), severe hypoglycemia was defined as an event with symptoms consistent with hypoglycemia requiring assistance of another person and associated with either a plasma glucose value below 56 mg/dL (blood glucose below 50 mg/dL) or prompt recovery after oral carbohydrate, intravenous glucose or glucagon administration. For the other pediatric trial (Study I), severe hypoglycemia was defined as an event with semi-consciousness, unconsciousness, coma and/ or convulsions in a patient who could not assist in the treatment and who may have required glucagon or intravenous glucose.
For the adult trials and pediatric Study D, non-severe hypoglycemia was defined as an asymptomatic or symptomatic plasma glucose < 56 mg/dL (or equivalently blood glucose < 50 mg/dL as used in Study A and C) that was self-treated by the patient. For pediatric Study I, non-severe hypoglycemia included asymptomatic events with plasma glucose < 65 mg/dL as well as symptomatic events that the patient could self-treat or treat by taking oral therapy provided by the caregiver.
The rates of hypoglycemia in the LEVEMIR® clinical trials (see Clinical Studies) were comparable between LEVEMIR®-treated patients and non-LEVEMIR®-treated patients (see Tables 5 and 6).

Insulin Initiation and Intensification of Glucose Control
Intensification or rapid improvement in glucose control has been associated with a transitory, reversible ophthalmologic refraction disorder, worsening of diabetic retinopathy, and acute painful peripheral neuropathy. However, long-term glycemic control decreases the risk of diabetic retinopathy and neuropathy.
Long-term use of insulin, including LEVEMIR®, can cause lipodystrophy at the site of repeated insulin injections. Lipodystrophy includes lipohypertrophy (thickening of adipose tissue) and lipoatrophy (thinning of adipose tissue), and may affect insulin absorption. Rotate insulin injection sites within the same region to reduce the risk of lipodystrophy [see DOSAGE AND ADMINISTRATION].
Weight gain can occur with insulin therapy, including LEVEMIR®, and has been attributed to the anabolic effects of insulin and the decrease in glucosuria [see Clinical Studies].
Insulin, including LEVEMIR®, may cause sodium retention and edema, particularly if previously poor metabolic control is improved by intensified insulin therapy.
As with any insulin therapy, patients taking LEVEMIR® may experience injection site reactions, including localized erythema, pain, pruritus, urticaria, edema, and inflammation. In clinical studies in adults, three patients treated with LEVEMIR® reported injection site pain (0.25%) compared to one patient treated with NPH insulin (0.12%). The reports of pain at the injection site did not result in discontinuation of therapy.
Rotation of the injection site within a given area from one injection to the next may help to reduce or prevent these reactions. In some instances, these reactions may be related to factors other than insulin, such as irritants in a skin cleansing agent or poor injection technique. Most minor reactions to insulin usually resolve in a few days to a few weeks.
Severe, life-threatening, generalized allergy, including anaphylaxis, generalized skin reactions, angioedema, bronchospasm, hypotension, and shock may occur with any insulin, including LEVEMIR®, and may be life-threatening [see WARNINGS AND PRECAUTIONS].
All insulin products can elicit the formation of insulin antibodies. These insulin antibodies may increase or decrease the efficacy of insulin and may require adjustment of the insulin dose. In phase 3 clinical trials of LEVEMIR®, antibody development has been observed with no apparent impact on glycemic control.
The following adverse reactions have been identified during post approval use of LEVEMIR®. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
Medication errors have been reported during post-approval use of LEVEMIR® in which other insulins, particularly rapid-acting or short-acting insulins, have been accidentally administered instead of LEVEMIR® [see PATIENT INFORMATION]. To avoid medication errors between LEVEMIR® and other insulins, patients should be instructed always to verify the insulin label before each injection.
A number of medications affect glucose metabolism and may require insulin dose adjustment and particularly close monitoring.
The following are examples of medications that may increase the blood-glucose-lowering effect of insulins including LEVEMIR® and, therefore, increase the susceptibility to hypoglycemia: oral antidiabetic medications, pramlintide acetate, angiotensin converting enzyme (ACE) inhibitors, disopyramide, fibrates, fluoxetine, monoamine oxidase (MAO) inhibitors, propoxyphene, pentoxifylline, salicylates, somatostatin analogs, and sulfonamide antibiotics.
The following are examples of medications that may reduce the blood-glucose-lowering effect of insulins including LEVEMIR®: corticosteroids, niacin, danazol, diuretics, sympathomimetic agents (e.g., epinephrine, albuterol, terbutaline), glucagon, isoniazid, phenothiazine derivatives, somatropin, thyroid hormones, estrogens, progestogens (e.g., in oral contraceptives), protease inhibitors and atypical antipsychotic medications (e.g. olanzapine and clozapine).
Beta-blockers, clonidine, lithium salts, and alcohol may either increase or decrease the blood-glucose-lowering effect of insulin. Pentamidine may cause hypoglycemia, which may sometimes be followed by hyperglycemia.
The signs of hypoglycemia may be reduced or absent in patients taking anti-adrenergic drugs such as beta-blockers, clonidine, guanethidine, and reserpine.
Included as part of the PRECAUTIONS section.
Never Share A LEVEMIR® FlexTouch® Between Patients
LEVEMIR® FlexTouch® must never be shared between patients, even if the needle is changed. Sharing poses a risk for transmission of blood-borne pathogens.
Dosage Adjustment And Monitoring
Glucose monitoring is essential for all patients receiving insulin therapy. Changes to an insulin regimen should be made cautiously and only under medical supervision.
Changes in insulin strength, manufacturer, type, or method of administration may result in the need for a change in the insulin dose or an adjustment of concomitant anti-diabetic treatment.
As with all insulin preparations, the time course of action for LEVEMIR® may vary in different individuals or at different times in the same individual and is dependent on many conditions, including the local blood supply, local temperature, and physical activity.
LEVEMIR® should only be administered subcutaneously.
Do not administer LEVEMIR® intravenously or intramuscularly. The intended duration of activity of LEVEMIR® is dependent on injection into subcutaneous tissue. Intravenous or intramuscular administration of the usual subcutaneous dose could result in severe hypoglycemia [see Hypoglycemia].
Do not use LEVEMIR® in insulin infusion pumps.
Do not dilute or mix LEVEMIR® with any other insulin or solution. If LEVEMIR® is diluted or mixed, the pharmacokinetic or pharmacodynamic profile (e.g., onset of action, time to peak effect) of LEVEMIR® and the mixed insulin may be altered in an unpredictable manner.
Hypoglycemia is the most common adverse reaction of insulin therapy, including LEVEMIR®. The risk of hypoglycemia increases with intensive glycemic control.
When a GLP-1 receptor agonist is used in combination with LEVEMIR®, the LEVEMIR® dose may need to be lowered or more conservatively titrated to minimize the risk of hypoglycemia [see ADVERSE REACTIONS].
All patients must be educated to recognize and manage hypoglycemia. Severe hypoglycemia can lead to unconsciousness or convulsions and may result in temporary or permanent impairment of brain function or death. Severe hypoglycemia requiring the assistance of another person or parenteral glucose infusion, or glucagon administration has been observed in clinical trials with insulin, including trials with LEVEMIR®.
The timing of hypoglycemia usually reflects the time-action profile of the administered insulin formulations. Other factors such as changes in food intake (e.g., amount of food or timing of meals), exercise, and concomitant medications may also alter the risk of hypoglycemia [see DRUG INTERACTIONS].
The prolonged effect of subcutaneous LEVEMIR® may delay recovery from hypoglycemia.
As with all insulins, use caution in patients with hypoglycemia unawareness and in patients who may be predisposed to hypoglycemia (e.g., the pediatric population and patients who fast or have erratic food intake). The patient's ability to concentrate and react may be impaired as a result of hypoglycemia. This may present a risk in situations where these abilities are especially important, such as driving or operating other machinery.
Early warning symptoms of hypoglycemia may be different or less pronounced under certain conditions, such as longstanding diabetes, diabetic neuropathy, use of medications such as beta-blockers, or intensified glycemic control [see DRUG INTERACTIONS]. These situations may result in severe hypoglycemia (and, possibly, loss of consciousness) prior to the patient's awareness of hypoglycemia.
Hypersensitivity And Allergic Reactions
No difference was observed in the pharmacokinetics of insulin detemir between non-diabetic individuals with renal impairment and healthy volunteers. However, some studies with human insulin have shown increased circulating insulin concentrations in patients with renal impairment. Careful glucose monitoring and dose adjustments of insulin, including LEVEMIR®, may be necessary in patients with renal impairment [see CLINICAL PHARMACOLOGY].
Non-diabetic individuals with severe hepatic impairment had lower systemic exposures to insulin detemir compared to healthy volunteers. However, some studies with human insulin have shown increased circulating insulin concentrations in patients with liver impairment. Careful glucose monitoring and dose adjustments of insulin, including LEVEMIR®, may be necessary in patients with hepatic impairment [see CLINICAL PHARMACOLOGY].
Fluid Retention And Heart Failure With Concomitant Use Of PPAR-gamma Agonists
Thiazolidinediones (TZDs), which are peroxisome proliferator-activated receptor (PPAR)-gamma agonists, can cause dose-related fluid retention, particularly when used in combination with insulin. Fluid retention may lead to or exacerbate heart failure. Patients treated with insulin, including LEVEMIR®, and a PPAR-gamma agonist should be observed for signs and symptoms of heart failure. If heart failure develops, it should be managed according to current standards of care, and discontinuation or dose reduction of the PPAR-gamma agonist must be considered.
Patient Counseling Information
See FDA-Approved Patient Labeling (PATIENT INFORMATION and Instructions for Use)
Never Share A LEVEMIR® FlexTouch® Between Patients
Advise patients that they must never share a LEVEMIR® FlexTouch® with another person, even if the needle is changed, because doing so carries a risk for transmission of bloodborne pathogens.
Instructions For Patients
Patients should be informed that changes to insulin regimens must be made cautiously and only under medical supervision. Patients should be informed about the potential side effects of insulin therapy, including hypoglycemia, weight gain, lipodystrophy (and the need to rotate injection sites within the same body region), and allergic reactions. Patients should be informed that the ability to concentrate and react may be impaired as a result of hypoglycemia. This may present a risk in situations where these abilities are especially important, such as driving or operating other machinery. Patients who have frequent hypoglycemia or reduced or absent warning signs of hypoglycemia should be advised to use caution when driving or operating machinery.
Accidental mix-ups between LEVEMIR® and other insulins, particularly short-acting insulins, have been reported. To avoid medication errors between LEVEMIR® and other insulins, patients should be instructed to always check the insulin label before each injection.
LEVEMIR® must only be used if the solution is clear and colorless with no particles visible. Patients must be advised that LEVEMIR® must NOT be diluted or mixed with any other insulin or solution.
Patients should be instructed on self-management procedures including glucose monitoring, proper injection technique, and management of hypoglycemia and hyperglycemia. Patients should be instructed on handling of special situations such as intercurrent conditions (illness, stress, or emotional disturbances), an inadequate or skipped insulin dose, inadvertent administration of an increased insulin dose, inadequate food intake, and skipped meals.
Patients should receive proper training on how to use Levemir®. Instruct patients that when injecting Levemir®, they must press and hold down the dose button until the dose counter shows 0 and then keep the needle in the skin and count slowly to 6. When the dose counter returns to 0, the prescribed dose is not completely delivered until 6 seconds later. If the needle is removed earlier, they may see a stream of insulin coming from the needle tip. If so, the full dose will not be delivered (a possible under-dose may occur by as much as 20%), and they should increase the frequency of checking their blood glucose levels and possible additional insulin administration may be necessary.
- If 0 does not appear in the dose counter after continuously pressing the dose button, the patient may have used a blocked needle. In this case they would not have received any insulin – even though the dose counter has moved from the original dose that was set.
- If the patient did have a blocked needle, instruct them to change the needle as described in Section 5 of the Instructions for Use and repeat all steps in the IFU starting with Section 1: Prepare your pen with a new needle. Make sure the patient selects the full dose needed.
Patients with diabetes should be advised to inform their healthcare professional if they are pregnant or are contemplating pregnancy. Refer patients to the LEVEMIR® “PATIENT INFORMATION” for additional information.
Carcinogenicity, Mutagenicity, Impairment Of Fertility
Standard 2-year carcinogenicity studies in animals have not been performed. Insulin detemir tested negative for genotoxic potential in the in vitro reverse mutation study in bacteria, human peripheral blood lymphocyte chromosome aberration test, and the in vivo mouse micronucleus test.
In a fertility and embryonic development study, insulin detemir was administered to female rats before mating, during mating, and throughout pregnancy at doses up to 300 nmol/kg/day (3 times a human dose of 0.5 Units/kg/day, based on plasma AUC ratio). There were no effects on fertility in the rat.
Use In Specific Populations
Pregnancy Category B
The background risk of birth defects, pregnancy loss, or other adverse events that exists for all pregnancies is increased in pregnancies complicated by hyperglycemia. Female patients should be advised to tell their physician if they intend to become, or if they become pregnant while taking LEVEMIR®. A randomized controlled clinical trial of pregnant women with type I diabetes using LEVEMIR® during pregnancy did not show an increase in the risk of fetal abnormalities. Reproductive toxicology studies in non-diabetic rats and rabbits that included concurrent human insulin control groups indicated that insulin detemir and human insulin had similar effects regarding embryotoxicity and teratogenicity that were attributed to maternal hypoglycemia.
The increased risk of adverse events in pregnancies complicated by hyperglycemia may be decreased with good glucose control before conception and throughout pregnancy. Because insulin requirements vary throughout pregnancy and in the post-partum period, careful monitoring of glucose control is essential in pregnant women.
In an, open-label, clinical study, women with type 1 diabetes who were (between weeks 8 and 12 of gestation) or intended to become pregnant were randomized 1:1 to LEVEMIR® (once or twice daily) or NPH insulin (once, twice or thrice daily). Insulin aspart was administered before each meal. A total of 152 women in the LEVEMIR® arm and 158 women in the NPH arm were or became pregnant during the study (Total pregnant women = 310). Approximately one half of the study participants in each arm were randomized as pregnant and were exposed to NPH or to other insulins prior to conception and in the first 8 weeks of gestation. In the 310 pregnant women, the mean glycosylated hemoglobin (HbA1c) was < 7% at 10, 12, and 24 weeks of gestation in both arms. In the intent-to-treat population, the adjusted mean HbA1c (standard error) at gestational week 36 was 6.27% (0.053) in LEVEMIR®-treated patient (n=138) and 6.33% (0.052) in NPH-treated patients (n=145); the difference was not clinically significant.
Adverse reactions in pregnant patients occurring at an incidence of ≥ 5% are shown in Table 7. The two most common adverse reactions were nasopharyngitis and headache. These are consistent with findings from other type 1 diabetes trials (see Table 1, ADVERSE REACTIONS.), and are not repeated in Table 7.
The incidence of adverse reactions of pre-eclampsia was 10.5% (16 cases) and 7.0% (11 cases) in the LEVEMIR® and NPH insulin groups respectively. Out of the total number of cases of pre-eclampsia, eight (8) cases in the LEVEMIR® group and 1 case in the NPH insulin group required hospitalization. The rates of pre-eclampsia observed in the study are within expected rates for pregnancy complicated by diabetes. Pre-eclampsia is a syndrome defined by symptoms, hypertension and proteinuria; the definition of pre-eclampsia was not standardized in the trial making it difficult to establish a link between a given treatment and an increased risk of pre-eclampsia. All events were considered unlikely related to trial treatment. In all nine (9) cases requiring hospitalization the women had healthy infants. Events of hypertension, proteinuria and edema were reported less frequently in the LEVEMIR® group than in the NPH insulin group as a whole. There was no difference between the treatment groups in mean blood pressure during pregnancy and there was no indication of a general increase in blood pressure.
In the NPH insulin group there were 6 serious adverse reactions in four mothers of the following placental disorders, 'Placenta previa', 'Placenta previa hemorrhage', and 'Premature separation of placenta' and 1 serious adverse reaction of 'Antepartum haemorrhage'. There were none reported in the LEVEMIR® group.
The incidence of early fetal death (abortions) was similar in LEVEMIR® and NPH treated patients; 6.6% and 5.1%, respectively. The abortions were reported under the following terms: 'Abortion spontaneous', 'Abortion missed', 'Blighted ovum', 'Cervical incompetence' and 'Abortion incomplete'.

|Abdominal pain upper||5.9||3.8|
|*Because clinical trials are conducted under widely varying designs, the adverse reaction rates reported in one clinical trial may not be easily compared to those rates reported in another clinical trial, and may not reflect the rates actually observed in clinical practice.|
The proportion of subjects experiencing severe hypoglycemia was 16.4% and 20.9% in LEVEMIR® and NPH treated patients respectively. The rate of severe hypoglycemia was 1.1 and 1.2 events per patient-year in LEVEMIR® and NPH treated patients respectively. Proportion and incidence rates for non-severe episodes of hypoglycemia were similar in both treatment groups (Table 8).

|* For definition regarding severe and non-severe hypoglycemia see ADVERSE REACTIONS, Hypoglycemia.|
In about a quarter of infants, LEVEMIR® was detected in the infant cord blood at levels above the lower level of quantification ( < 25 pmol/L).
No differences in pregnancy outcomes or the health of the fetus and newborn were seen with LEVEMIR® use.
In a fertility and embryonic development study, insulin detemir was administered to female rats before mating, during mating, and throughout pregnancy at doses up to 300 nmol/kg/day (3 times a human dose of 0.5 Units/kg/day, based on plasma area under the curve (AUC) ratio). Doses of 150 and 300 nmol/kg/day produced numbers of litters with visceral anomalies. Doses up to 900 nmol/ kg/day (approximately 135 times a human dose of 0.5 Units/kg/day based on AUC ratio) were given to rabbits during organogenesis. Drug and dose related increases in the incidence of fetuses with gallbladder abnormalities such as small, bilobed, bifurcated, and missing gallbladders were observed at a dose of 900 nmol/ kg/day. The rat and rabbit embryofetal development studies that included concurrent human insulin control groups indicated that insulin detemir and human insulin had similar effects regarding embryotoxicity and teratogenicity suggesting that the effects seen were the result of hypoglycemia resulting from insulin exposure in normal animals.
It is unknown whether LEVEMIR® is excreted in human milk. Because many drugs, including human insulin, are excreted in human milk, use caution when administering LEVEMIR® to a nursing woman. Women with diabetes who are lactating may require adjustments of their insulin doses.
The pharmacokinetics, safety and effectiveness of subcutaneous injections of LEVEMIR® have been established in pediatric patients (age 2 to 17 years) with type 1 diabetes [see CLINICAL PHARMACOLOGY and Clinical Studies]. LEVEMIR® has not been studied in pediatric patients younger than 2 years of age with type 1 diabetes. LEVEMIR® has not been studied in pediatric patients with type 2 diabetes.
The dose recommendation when converting to LEVEMIR® is the same as that described for adults [see DOSAGE AND ADMINISTRATION and Clinical Studies]. As in adults, the dosage of LEVEMIR® must be individualized in pediatric patients based on metabolic needs and frequent monitoring of blood glucose.
In controlled clinical trials comparing LEVEMIR® to NPH insulin or insulin glargine, 64 of 1624 patients (3.9%) in the type 1 diabetes trials and 309 of 1082 patients (28.6%) in the type 2 diabetes trials were ≥ 65 years of age. A total of 52 (7 type 1 and 45 type 2) patients (1.9%) were ≥ 75 years of age. No overall differences in safety or effectiveness were observed between these patients and younger patients, but small sample sizes, particularly for patients ≥ 65 years of age in the type 1 diabetes trials and for patients ≥ 75 years of age in all trials limits conclusions. Greater sensitivity of some older individuals cannot be ruled out. In elderly patients with diabetes, the initial dosing, dose increments, and maintenance dosage should be conservative to avoid hypoglycemia. Hypoglycemia may be difficult to recognize in the elderly.
An excess of insulin relative to food intake, energy expenditure, or both may lead to severe and sometimes prolonged and life-threatening hypoglycemia. Mild episodes of hypoglycemia usually can be treated with oral glucose. Adjustments in drug dosage, meal patterns, or exercise may be needed.
More severe episodes with coma, seizure, or neurologic impairment may be treated with intramuscular/subcutaneous glucagon or concentrated intravenous glucose. After apparent clinical recovery from hypoglycemia, continued observation and additional carbohydrate intake may be necessary to avoid recurrence of hypoglycemia [see WARNINGS AND PRECAUTIONS].
Mechanism Of Action
The primary activity of insulin detemir is the regulation of glucose metabolism. Insulins, including insulin detemir, exert their specific action through binding to insulin receptors. Receptor-bound insulin lowers blood glucose by facilitating cellular uptake of glucose into skeletal muscle and adipose tissue and by inhibiting the output of glucose from the liver. Insulin inhibits lipolysis in the adipocyte, inhibits proteolysis, and enhances protein synthesis.
Insulin detemir is a soluble, long-acting basal human insulin analog with up to a 24-hour duration of action. The pharmacodynamic profile of LEVEMIR® is relatively constant with no pronounced peak.
The duration of action of LEVEMIR® is mediated by slowed systemic absorption of insulin detemir molecules from the injection site due to self-association of the drug molecules. In addition, the distribution of insulin detemir to peripheral target tissues is slowed because of binding to albumin.
Figure 2 shows results from a study in patients with type 1 diabetes conducted for a maximum of 24 hours after the subcutaneous injection of LEVEMIR® or NPH insulin. The mean time between injection and the end of pharmacological effect for insulin detemir ranged from 7.6 hours to > 24 hours (24 hours was the end of the observation period).

Diabetes in a 24-hour Glucose Clamp Study
AUCGIR: Area Under Curve for Glucose Infusion Rate
GIRmax: Maximum Glucose Infusion Rate
For doses in the interval of 0.2 to 0.4 Units/kg, insulin detemir exerts more than 50% of its maximum effect from 3 to 4 hours up to approximately 14 hours after dose administration.
Figure 3 shows glucose infusion rate results from a 16-hour glucose clamp study in patients with type 2 diabetes. The clamp study was terminated at 16 hours according to protocol.

Absorption and Bioavailability
After subcutaneous injection of LEVEMIR® in healthy subjects and in patients with diabetes, insulin detemir serum concentrations had a relatively constant concentration/time profile over 24 hours with the maximum serum concentration (Cmax) reached between 6-8 hours post-dose. Insulin detemir was more slowly absorbed after subcutaneous administration to the thigh where AUC0-5h was 30-40% lower and AUC0-inf was 10% lower than the corresponding AUCs with subcutaneous injections to the deltoid and abdominal regions.
The absolute bioavailability of insulin detemir is approximately 60%.
Distribution and Elimination
More than 98% of insulin detemir in the bloodstream is bound to albumin. The results of in vitro and in vivo protein binding studies demonstrate that there is no clinically relevant interaction between insulin detemir and fatty acids or other protein-bound drugs.
Insulin detemir has an apparent volume of distribution of approximately 0.1 L/kg. After subcutaneous administration in patients with type 1 diabetes, insulin detemir has a terminal half-life of 5 to 7 hours depending on dose.
Children and Adolescents - The pharmacokinetic properties of LEVEMIR® were investigated in children (6-12 years), adolescents (13-17 years), and adults with type 1 diabetes. In children, the insulin detemir plasma area under the curve (AUC) and Cmax were increased by 10% and 24%, respectively, as compared to adults. There was no difference in pharmacokinetics between adolescents and adults.
Geriatrics - In a clinical trial investigating differences in pharmacokinetics of a single subcutaneous dose of LEVEMIR® in young (20 to 35 years) versus elderly ( ≥ 68 years) healthy subjects, the insulin detemir AUC was up to 35% higher among the elderly subjects due to reduced clearance. As with other insulin preparations, LEVEMIR® should always be titrated according to individual requirements.
Gender - No clinically relevant differences in pharmacokinetic parameters of LEVEMIR® are observed between males and females.
Race - In two clinical pharmacology studies conducted in healthy Japanese and Caucasian subjects, there were no clinically relevant differences seen in pharmacokinetic parameters. The pharmacokinetics and pharmacodynamics of LEVEMIR® were investigated in a clamp study comparing patients with type 2 diabetes of Caucasian, African-American, and Latino origin. Dose-response relationships for LEVEMIR® were comparable in these three populations.
Renal impairment - A single subcutaneous dose of 0.2 Units/kg (1.2 nmol/kg) of LEVEMIR® was administered to healthy subjects and those with varying degrees of renal impairment (mild, moderate, severe, and hemodialysis-dependent). In this study, there were no differences in the pharmacokinetics of LEVEMIR® between healthy subjects and those with renal impairment. However, some studies with human insulin have shown increased circulating levels of insulin in patients with renal impairment. Careful glucose monitoring and dose adjustments of insulin, including LEVEMIR®, may be necessary in patients with renal impairment [see WARNINGS AND PRECAUTIONS].
Hepatic impairment - A single subcutaneous dose of 0.2 Units/kg (1.2 nmol/kg) of LEVEMIR® was administered to healthy subjects and those with varying degrees of hepatic impairment (mild, moderate and severe). LEVEMIR® exposure as estimated by AUC decreased with increasing degrees of hepatic impairment with a corresponding increase in apparent clearance. However, some studies with human insulin have shown increased circulating levels of insulin in patients with liver impairment. Careful glucose monitoring and dose adjustments of insulin, including LEVEMIR®, may be necessary in patients with hepatic impairment [see WARNINGS AND PRECAUTIONS].
Pregnancy - The effect of pregnancy on the pharmacokinetics and pharmacodynamics of LEVEMIR® has not been studied [see Use in Specific Populations].
Smoking - The effect of smoking on the pharmacokinetics and pharmacodynamics of LEVEMIR® has not been studied.
Liraglutide - No pharmacokinetic interaction was observed between liraglutide and LEVEMIR® when separate subcutaneous injections of LEVEMIR® 0.5 Unit/kg (single-dose) and liraglutide 1.8 mg (steady state) were administered in patients with type 2 diabetes.
The efficacy and safety of LEVEMIR® given once-daily at bedtime or twice-daily (before breakfast and at bedtime, before breakfast and with the evening meal, or at 12-hour intervals) was compared to that of once-daily or twice-daily NPH insulin in open-label, randomized, parallel studies of 1155 adults with type 1 diabetes mellitus, 347 pediatric patients with type 1 diabetes mellitus, and 869 adults with type 2 diabetes mellitus. The efficacy and safety of LEVEMIR® given twice-daily was compared to once-daily insulin glargine in an open-label, randomized, parallel study of 320 patients with type 1 diabetes. The evening LEVEMIR® dose was titrated in all trials according to pre-defined targets for fasting blood glucose. The pre-dinner blood glucose was used to titrate the morning LEVEMIR® dose in those trials that also administered LEVEMIR® in the morning. In general, the reduction in glycosylated hemoglobin (HbA1c) with LEVEMIR® was similar to that with NPH insulin or insulin glargine.
Type 1 Diabetes – Adult
In a 16-week open-label clinical study (Study A, n=409), adults with type 1 diabetes were randomized to treatment with either LEVEMIR® at 12-hour intervals, LEVEMIR® administered in the morning and bedtime or NPH insulin administered in the morning and bedtime. Insulin aspart was also administered before each meal. At 16 weeks of treatment, the combined LEVEMIR®-treated patients had similar HbA1c and fasting plasma glucose (FPG) reductions compared to the NPH-treated patients (Table 9). Differences in timing of LEVEMIR® administration had no effect on HbA1c, fasting plasma glucose (FPG), or body weight.
In a 26-week, open-label clinical study (Study B, n=320), adults with type 1 diabetes were randomized to twice-daily LEVEMIR® (administered in the morning and bedtime) or once-daily insulin glargine (administered at bedtime). Insulin aspart was administered before each meal. LEVEMIR®-treated patients had a decrease in HbA1c similar to that of insulin glargine-treated patients.
In a 24-week, open-label clinical study (Study C, n=749), adults with type 1 diabetes were randomized to once-daily LEVEMIR® or once-daily NPH insulin, both administered at bedtime and in combination with regular human insulin before each meal. LEVEMIR® and NPH insulin had a similar effect on HbA1c.

Type 1 Diabetes – Pediatric
Two open-label, randomized, controlled clinical studies have been conducted in pediatric patients with type 1 diabetes. One study was 26 weeks in duration and enrolled patients 6-17 years of age. The other study was 52 weeks in duration and enrolled patients 2-16 years of age. In both studies, LEVEMIR® and NPH insulin were administered once- or twice-daily. Bolus insulin aspart was administered before each meal. In the 26-week study, LEVEMIR®-treated patients had a mean decrease in HbA1c similar to that of NPH insulin (Table 10). In the 52-week study, the randomization was stratified by age (2-5 years, n=82, and 6-16 years, n=265) and the mean HbA1c increased in both treatment arms, with similar findings in the 2-5 year-old age group (n=80) and the 6-16 year-old age group (n=258) (Table 10).

Type 2 Diabetes – Adult
In a 24-week, open-label, randomized, clinical study (Study E, n=476), LEVEMIR® administered twice-daily (before breakfast and evening) was compared to NPH insulin administered twice-daily (before breakfast and evening) as part of a regimen of stable combination therapy with one or two of the following oral antidiabetic medications: metformin, an insulin secretagogue, or an alpha– glucosidase inhibitor. All patients were insulin-naïve at the time of randomization. LEVEMIR® and NPH insulin similarly lowered HbA1c from baseline (Table 11).
In a 22-week, open-label, randomized, clinical study (Study F, n=395) in adults with type 2 diabetes, LEVEMIR® and NPH insulin were given once- or twice-daily as part of a basal-bolus regimen with insulin aspart. As measured by HbA1c or FPG, LEVEMIR® had efficacy similar to that of NPH insulin.

Combination Therapy with Metformin and Liraglutide
This 26-week open-label trial enrolled 988 patients with inadequate glycemic control (HbA1c 7-10%) on metformin ( ≥ 1500 mg/day) alone or inadequate glycemic control (HbA1c 7-8.5%) on metformin ( ≥ 1500 mg/day) and a sulfonylurea. Patients who were on metformin and a sulfonylurea discontinued the sulfonylurea then all patients entered a 12-week run-in period during which they received add-on therapy with liraglutide titrated to 1.8 mg once-daily. At the end of the run-in period, 498 patients (50%) achieved HbA1c < 7% with liraglutide 1.8 mg and metformin and continued treatment in a non-randomized, observational arm. Another 167 patients (17%) withdrew from the trial during the run-in period with approximately one-half of these patients doing so because of gastrointestinal adverse reactions [see ADVERSE REACTIONS]. The remaining 323 patients with HbA1c ≥ 7% (33% of those who entered the run-in period) were randomized to 26 weeks of once-daily LEVEMIR® administered in the evening as add-on therapy (N=162) or to continued, unchanged treatment with liraglutide 1.8 mg and metformin (N=161). The starting dose of LEVEMIR® was 10 units/day and the mean dose at the end of the 26-week randomized period was 39 units/day. During the 26-week randomized treatment period, the percentage of patients who discontinued due to ineffective therapy was 11.2% in the group randomized to continued treatment with liraglutide 1.8 mg and metformin and 1.2% in the group randomized to add-on therapy with LEVEMIR®.
Treatment with LEVEMIR® as add-on to liraglutide 1.8 mg + metformin resulted in statistically significant reductions in HbA1c and FPG compared to continued, unchanged treatment with liraglutide 1.8 mg + metformin alone (Table 12). From a mean baseline body weight of 96 kg after randomization, there was a mean reduction of 0.3 kg in the patients who received LEVEMIR® add-on therapy compared to a mean reduction of 1.1 kg in the patients who continued on unchanged treatment with liraglutide 1.8 mg + metformin alone.

- Read the Instructions for Use that come with your Levemir®.
- Take Levemir®exactly as your healthcare provider tells you to.
- Know the type and strength of insulin you take. Do not change the type of insulin you take unless your healthcare provider tells you to. The amount of insulin and the best time for you to take your insulin may need to change if you take different types of insulin.
- Check your blood sugar levels. Ask your healthcare provider what your blood sugars should be and when you should check your blood sugar levels.
- Do not reuse or share your needles or syringes with other people. You may give other people a serious infection, or get a serious infection from them.
- Never inject Levemir® into a vein or muscle.
What should I avoid while taking Levemir®?
While taking Levemir® do not:
- Drive or operate heavy machinery, until you know how Levemir® affects you.
- Drink alcohol or use prescription or over-the-counter medicines that contain alcohol.
What are the possible side effects of Levemir®?
Levemir® may cause serious side effects that can lead to death, including:
Low blood sugar (hypoglycemia). Signs and symptoms that may indicate low blood sugar include:
- dizziness or light-headedness
- blurred vision
- anxiety, irritability, or mood changes
- slurred speech
- fast heart beat
Your insulin dose may need to change because of:
- change in level of physical activity or exercise

- weight gain or loss
Other common side effects of Levemir® may include:
- Reactions at the injection site, itching, rash, serious allergic reactions (whole body reactions), skin thickening or pits at the injection site (lipodystrophy), weight gain, and swelling of your hands and feet.
Get emergency medical help if you have:
- trouble breathing, shortness of breath, fast heartbeat, swelling of your face, tongue, or throat, sweating, extreme drowsiness, dizziness, confusion.
These are not all the possible side effects of Levemir®. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
General information about the safe and effective use of Levemir®.
Medicines are sometimes prescribed for purposes other than those listed in a Patient Information leaflet. You can ask your pharmacist or healthcare provider for information about Levemir®that is written for health professionals. Do not use Levemir®for a condition for which it was not prescribed. Do not give Levemir®to other people, even if they have the same symptoms that you have. It may harm them.
What are the ingredients in Levemir®?
Active Ingredient: insulin detemir (rDNA origin)
Patient Instructions For Use
LEVEMIR® 10 mL vial
Please read the following Instructions for use carefully before using your LEVEMIR® 10 mL vial and each time you get a refill. You should read the instructions in this manual even if you have used an insulin 10 mL vial before.
How should I use the LEVEMIR® 10 mL vial?
Using the 10 mL vial:
1. Check to make sure that you have the correct type of insulin. This is especially important if you use different types of insulin.
2. Look at the vial and the insulin. The LEVEMIR® insulin should be clear and colorless. The tamper-resistant cap should be in place before the first use. If the cap has been removed before your first use of the vial, or if the insulin is cloudy or colored, Do not use the insulin and return it to your pharmacy.
3. Wash your hands with soap and water.
4. If you are using a new vial, pull off the tamper-resistant cap.
Before each use, wipe the rubber stopper with an alcohol wipe.
5. Do not roll or shake the vial. Shaking the vial right before the dose is drawn into the syringe may cause bubbles or foam. This can cause you to draw up the wrong dose of insulin. The insulin should be used only if it is clear and colorless.
6. Pull back the plunger on your syringe until the black tip reaches the marking for the number of units you will inject.
7. Push the needle through the rubber stopper into the vial.
8. Push the plunger all the way in. This inserts air into the vial.
9. Turn the vial and syringe upside down and slowly pull the plunger back to a few units beyond the correct dose that you need.
10. If there are air bubbles, tap the syringe gently with your finger to raise the air bubbles to the top of the needle. Then slowly push the plunger to the correct unit marking for your dose.
11. Check to make sure you have the right dose of LEVEMIR® in the syringe.
12. Pull the syringe out of the vial.
13. Inject your LEVEMIR® right away as instructed by your healthcare provider.
How should I inject LEVEMIR® with a syringe?
If you clean your injection site with an alcohol swab, let the injection site dry before you inject. Talk with your healthcare provider about how to rotate injection sites and how to give an injection.
1. Pinch your skin between two fingers, push the needle into the skinfold, using a dart-like motion and push the plunger to inject the insulin under your skin. The needle will be straight in.
2. Keep the needle under your skin for at least 6 seconds to make sure you have injected all the insulin. After you pull the needle from your skin you may see a drop of Levemir® at the needle tip. This is normal and has no effect on the dose you just received.

Preparing your Levemir® FlexTouch® Pen:
- Wash your hands with soap and water.
- Before you start to prepare your injection, check the Levemir® FlexTouch® Pen label to make sure you are taking the right type of insulin. This is especially important if you take more than 1 type of insulin.
- Levemir® should look clear and colorless. Do not use Levemir® if it is thick, cloudy, or is colored.
- Do not use Levemir® past the expiration date printed on the label or 42 days after you start using the Pen.
- Always use a new needle for each injection to help ensure sterility and prevent blocked needles. Do not reuse or share your needles with other people. You may give other people a serious infection, or get a serious infection from them.
- Pull Pen cap straight off (See Figure B).
- Check the liquid in the Pen (See Figure ). Levemir® should look clear and colorless. Do not use it if it looks cloudy or colored.
- Select a new needle.
- Pull off the paper tab from the outer needle cap (See Figure D).
- Push the capped needle straight onto the Pen and twist the needle on until it is tight (See Figure E).
- Pull off the outer needle cap. Do not throw it away (See Figure F).
- Pull off the inner needle cap and throw it away (See Figure G).
Priming your Levemir® FlexTouch® Pen:
- Turn the dose selector to select 2 units (See Figure H).
- Hold the Pen with the needle pointing up. Tap the top of the Pen gently a few times to let any air bubbles rise to the top (See Figure I).
- Hold the Pen with the needle pointing up. Press and hold in the dose button until the dose counter shows “0”. The “0” must line up with the dose pointer.
- A drop of insulin should be seen at the needle tip (See
- If you do not see a drop of insulin, repeat steps 7 to 9, no more than 6 times.
- If you still do not see a drop of insulin, change the needle and repeat steps 7 to 9.
Selecting your dose:
- Turn the dose selector to select the number of units
you need to inject. The dose pointer should line up with your dose (See
- If you select the wrong dose, you can turn the dose selector forwards or backwards to the correct dose.
- The even numbers are printed on the dial.
- The odd numbers are shown as lines.
- The Levemir® FlexTouch® Pen insulin scale will show you how much insulin is left in your Pen (See Figure L).
- To see how much insulin is left in your Levemir® FlexTouch®
- Turn the dose selector until it stops. The dose counter will line up with the number of units of insulin that is left in your Pen. If the dose counter shows 80, there are at least 80 units left in your Pen.
- If the dose counter shows less than 80, the number shown in the dose counter is the number of units left in your Pen.
Giving your injection:
- Inject your Levemir® exactly as your healthcare provider has shown you. Your healthcare provider should tell you if you need to pinch the skin before injecting.
- Levemir® can be injected under the skin (subcutaneously) of your stomach area (abdomen), upper legs (thighs) or upper arms.
- For each injection, change (rotate) your injection site within the area of skin that you use. Do not use the same injection site for each injection.
- Choose your injection site and wipe the skin with an alcohol swab. Let the injection site dry before you inject your dose (See Figure M).
- Insert the needle into your skin (See Figure N).
- Make sure you can see the dose counter. Do not cover it with your fingers, this can stop your injection.
- Press and hold down the dose button until the dose counter shows “0” (See Figure O).
- The “0” must line up with the dose pointer. You may then hear or feel a click.
- Keep the needle in your skin after the dose
counter has returned to “0” and slowly count to 6 (See Figure P).
- When the dose counter returns to “0”, you will not get your full dose until 6 seconds later.
- If the needle is removed before you count to 6, you may see a stream of insulin coming from the needle tip.
- If you see a stream of insulin coming from the needle tip you will not get your full dose. If this happens you should check your blood sugar levels more often because you may need more insulin.
- Pull the needle out of your skin (See Figure Q).
- If you see blood after you take the needle out of your skin, press the injection site lightly with a piece of gauze or an alcohol swab. Do not rub the area.
- Carefully remove the needle from the Pen and throw it away (See Figure R).
- Do not recap the needle. Recapping the needle can lead to needle stick injury.
- If you do not have a sharps container, carefully
slip the needle into the outer needle cap (See Figure S). Safely remove the
needle and throw it away as soon as you can.
- Do not store the Pen with the needle attached. Storing without the needle attached helps prevent leaking, blocking of the needle, and air from entering the Pen.
- Replace the Pen cap by pushing it straight on (See Figure T).
After your injection:
- You can put your used Levemir® FlexTouch® Pen and needles in a FDA-cleared sharps disposal container right away after use. Do not throw away (dispose of) loose needles and Pens in your household trash.

- made of a heavy-duty plastic
- can be closed with a tight-fitting, puncture-resistant lid, without sharps being able to come out
- upright and stable during use
- properly labeled to warn of hazardous waste inside the container
- When your sharps disposal container is almost full, you will need to follow your community guidelines for the right way to dispose of your sharps disposal container.
