Avandaryl (rosiglitazone maleate and glimepiride) contains two oral antidiabetic drugs used to treat type 2 diabetes. Avandaryl is not for treating type 1 diabetes. It is not recommended for use with insulin. Avandaryl may increase your risk of serious heart problems, such as heart attack or stroke. Avandaryl is available only to certain people with type 2 diabetes that cannot be controlled with other diabetes medications. Avandaryl is available only under a special program called Avandia-Rosiglitazone Medicines Access Program. You must be registered in the program and sign documents stating that you understand the risks and benefits of taking Avandaryl. Common side effects of Avandaryl include:
Avandaryl can cause low blood sugar (hypoglycemia). Symptoms of low blood sugar include:
- cold sweat
- blurred vision
- rapid heart rate
- tingling of the hands/feet
Tell your doctor if you have serious side effects of Avandaryl including:
- bone fracture,
- yellowing eyes or skin,
- stomach or abdominal pain,
- persistent nausea or vomiting,
- dark urine,
- easy bruising or bleeding,
- signs of infection (e.g., fever, persistent sore throat),
- mental/mood changes, or
- vision changes (e.g., color or night vision problems).
The recommended starting dose of Avandaryl is 4 mg/1 mg administered once daily with the first meal of the day. Avandaryl may interact with delavirdine, gemfibrozil, other diabetes medications, antibiotics, antifungals, heart or blood pressure medications, pain or arthritis medicines, or seizure medicines. High blood sugar (hyperglycemia) may occur if you also take: isoniazid, diuretics, steroids, niacin, phenothiazines, thyroid medicine, birth control pills and other hormones, and diet pills or medicines to treat asthma, colds or allergies. Low blood sugar (hypoglycemia) may occur if you also take: exenatide, probenecid, aspirin or other salicylates, blood thinners, sulfa drugs, monoamine oxidase inhibitors (MAOIs), or other oral diabetes medications. Tell your doctor all medications and supplements you use. Avandaryl is not recommended for use during pregnancy. Insulin treatment may be preferred. Use of this medication close to the expected delivery date may increase the risk of low blood sugar in your newborn. Consult your doctor and follow all instructions carefully. It is unknown if this medication passes into breast milk, and it may have undesirable effects on a nursing infant. Breastfeeding while using this drug is not recommended.

Avandaryl Overview - Patient Information: Side Effects
Headache or sore throat may occur. If either of these effects persist or worsen, notify your doctor or pharmacist promptly.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
Tell your doctor right away if you have any serious side effects, including: bone fracture, yellowing eyes/skin, stomach/abdominal pain, persistent nausea/vomiting, dark urine, easy bruising/bleeding, signs of infection (e.g., fever, persistent sore throat), mental/mood changes, vision changes (e.g., color or night vision problems).
Get medical help right away if you have any very serious side effects, including: chest/jaw/left arm pain, unusual sweating, seizures.
This medication can cause low blood sugar (hypoglycemia). This effect may occur if you do not consume enough calories (from food, juices, fruit, etc.). The symptoms include chills, cold sweat, blurred vision, dizziness, drowsiness, shaking, rapid heart rate, weakness, headache, fainting, tingling of the hands/feet, and hunger. It is a good habit to carry glucose tablets or gel to treat low blood sugar. If you are in a situation where you don't have these reliable forms of glucose, eat a quick source of sugar such as table sugar, honey, or candy, or drink a glass of orange juice or non-diet soda to quickly raise your blood sugar level. Tell your doctor immediately about the reaction. To help prevent hypoglycemia, eat meals on a regular schedule and do not skip meals.
Symptoms of high blood sugar (hyperglycemia) include thirst, increased urination, confusion, drowsiness, flushing, rapid breathing, and fruity breath odor. If these symptoms occur, tell your doctor immediately. Your medication dosage may need to be increased.
A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.

Clinical Trial Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared with rates in the clinical trials of another drug and may not reflect the rates observed in practice.
Patients With Inadequate Glycemic Control On Diet and Exercise
Table 3 summarizes adverse events occurring at a frequency of ≥ 5% in any treatment group in the 28-week, double-blind trial of AVANDARYL in patients with type 2 diabetes mellitus inadequately controlled on diet and exercise. Patients in this trial were started on AVANDARYL 4 mg/1 mg, rosiglitazone 4 mg, or glimepiride 1 mg. Doses could be increased at 4-week intervals to reach a maximum total daily dose of either 4 mg/4 mg or 8 mg/4 mg for AVANDARYL, 8 mg for rosiglitazone monotherapy, or 4 mg for glimepiride monotherapy.

Hypoglycemia was reported to be generally mild to moderate in intensity and none of the reported events of hypoglycemia resulted in withdrawal from the trial. Hypoglycemia requiring parenteral treatment (i.e., intravenous glucose or glucagon injection) was observed in 3 (0.7%) patients treated with AVANDARYL.
Edema was reported by 3.2% of patients on AVANDARYL, 3.0% on rosiglitazone alone, and 2.3% on glimepiride alone.
Congestive heart failure was observed in 1 (0.2%) patient treated with AVANDARYL and in 1 (0.4%) patient treated with rosiglitazone monotherapy.
Patients Treated With Rosiglitazone Added To Sulfonylurea Monotherapy And Other Experience With Rosiglitazone Or Glimepiride
Trials utilizing rosiglitazone in combination with a sulfonylurea provide support for the use of AVANDARYL. Adverse event data from these trials, in addition to adverse events reported with the use of rosiglitazone and glimepiride therapy, are presented below.
Rosiglitazone: The most common adverse experiences with rosiglitazone monotherapy ( ≥ 5%) were upper respiratory tract infection, injury, and headache. Overall, the types of adverse experiences reported when rosiglitazone was added to a sulfonylurea were similar to those during monotherapy with rosiglitazone. In controlled combination therapy trials with sulfonylureas, mild to moderate hypoglycemic symptoms, which appear to be dose-related, were reported. Few patients were withdrawn for hypoglycemia ( < 1%) and few episodes of hypoglycemia were considered to be severe ( < 1%).
Events of anemia and edema tended to be reported more frequently at higher doses, and were generally mild to moderate in severity and usually did not require discontinuation of treatment with rosiglitazone.
Edema was reported by 4.8% of patients receiving rosiglitazone compared with 1.3% on placebo, and 1.0% on sulfonylurea monotherapy. The reporting rate of edema was higher for rosiglitazone 8 mg added to a sulfonylurea (12.4%) compared with other combinations, with the exception of insulin. Anemia was reported by 1.9% of patients receiving rosiglitazone compared with 0.7% on placebo, 0.6% on sulfonylurea monotherapy, and 2.3% on rosiglitazone in combination with a sulfonylurea. Overall, the types of adverse experiences reported when rosiglitazone was added to a sulfonylurea were similar to those during monotherapy with rosiglitazone.
In 26-week, double-blind, fixed-dose trials, edema was reported with higher frequency in the rosiglitazone plus insulin combination trials (insulin, 5.4%; and rosiglitazone in combination with insulin, 14.7%). Reports of new onset or exacerbation of congestive heart failure occurred at rates of 1% for insulin alone, and 2% (4 mg) and 3% (8 mg) for insulin in combination with rosiglitazone [see BOXED WARNING, WARNINGS AND PRECAUTIONS].
Long-term Trial of Rosiglitazone as Monotherapy: A 4- to 6-year trial (ADOPT) compared the use of rosiglitazone (n = 1,456), glyburide (n = 1,441), and metformin (n = 1,454) as monotherapy in patients recently diagnosed with type 2 diabetes who were not previously treated with antidiabetic medication. Table 4 presents adverse reactions without regard to causality; rates are expressed per 100 patient-years (PY) exposure to account for the differences in exposure to trial medication across the 3 treatment groups.
In ADOPT, fractures were reported in a greater number of women treated with rosiglitazone (9.3%, 2.7/100 patient-years) compared with glyburide (3.5%, 1.3/100 patient-years) or metformin (5.1%, 1.5/100 patient-years). The majority of the fractures in the women who received rosiglitazone were reported in the upper arm, hand, and foot. [See WARNINGS AND PRECAUTIONS] The observed incidence of fractures for male patients was similar among the 3 treatment groups.

Long-term Trial of Rosiglitazone as Combination Therapy (RECORD): RECORD (Rosiglitazone Evaluated for Cardiac Outcomes and Regulation of Glycemia in Diabetes) was a multicenter, randomized, open-label, non-inferiority trial in subjects with type 2 diabetes inadequately controlled on maximum doses of metformin or sulfonylurea (glyburide, gliclazide, or glimepiride) to compare the time to reach the combined cardiovascular endpoint of cardiovascular death or cardiovascular hospitalization between patients randomized to the addition of rosiglitazone versus metformin or sulfonylurea. The trial included patients who have failed metformin or sulfonylurea monotherapy; those who failed metformin (n = 2,222) were randomized to receive either add-on rosiglitazone (n = 1,117) or add-on sulfonylurea (n = 1,105), and those who failed sulfonylurea (n = 2,225) were randomized to receive either add-on rosiglitazone (n = 1,103) or add-on metformin (n = 1,122). Patients were treated to target HbA1c ≤ 7% throughout the trial.
The mean age of patients in this trial was 58 years, 52% were male, and the mean duration of follow-up was 5.5 years. Rosiglitazone demonstrated non-inferiority to active control for the primary endpoint of cardiovascular hospitalization or cardiovascular death (HR 0.99, 95% CI: 0.85-1.16). There were no significant differences between groups for secondary endpoints with the exception of congestive heart failure (see Table 5). The incidence of congestive heart failure was significantly greater among patients randomized to rosiglitazone.

N = 2,220
N = 2,227
|Hazard Ratio||95% CI|
|CV death or CV hospitalization||321||323||0.99||0.85-1.16|
|CV death, myocardial infarction, or stroke||154||165||0.93||0.74-1.15|
There was an increased incidence of bone fracture for subjects randomized to rosiglitazone in addition to metformin or sulfonylurea compared with those randomized to metformin plus sulfonylurea (8.3% versus 5.3%) [see WARNINGS AND PRECAUTIONS]. The majority of fractures were reported in the upper limbs and distal lower limbs. The risk of fracture appeared to be higher in females relative to control (11.5% versus 6.3%), than in males relative to control (5.3% versus 4.3%). Additional data are necessary to determine whether there is an increased risk of fracture in males after a longer period of follow-up.
Glimepiride: Approximately 2,800 patients with type 2 diabetes have been treated with glimepiride in the controlled clinical trials. In these trials, approximately 1,700 patients were treated with glimepiride for at least 1 year.
Table 6 summarizes adverse events, other than hypoglycemia, that were reported in 11 pooled placebo-controlled trials, whether or not considered to be possibly or probably related to study medication. Treatment duration ranged from 13 weeks to 12 months. Terms that are reported represent those that occurred at an incidence of ≥ 5% among glimepiride-treated patients and more commonly than in patients who received placebo.

N = 745 %
N = 294 %
|a Glimepiride doses ranges from 1 to 16 mg
b Insufficient information to determine whether any of the accidental injury events were associated with hypoglycemia.
Hypoglycemia: In a randomized, double-blind, placebo-controlled monotherapy trial of 14 weeks duration, patients already on sulfonylurea therapy underwent a 3-week washout period then were randomized to glimepiride 1 mg, 4 mg, 8 mg or placebo. Patients randomized to glimepiride 4 mg or 8 mg underwent forced-titration from an initial dose of 1 mg to these final doses, as tolerated. The overall incidence of possible hypoglycemia (defined by the presence of at least one symptom that the investigator believed might be related to hypoglycemia; a concurrent glucose measurement was not required) was 4% for glimepiride 1 mg, 17% for glimepiride 4 mg, 16% for glimepiride 8 mg, and 0% for placebo. All of these events were self-treated.
In a randomized, double-blind, placebo-controlled monotherapy trial of 22 weeks duration, patients received a starting dose of either 1 mg glimepiride or placebo daily. The dose of glimepiride was titrated to a target fasting plasma glucose of 90 to 150 mg/dL. Final daily doses of glimepiride were 1, 2, 3, 4, 6, or 8 mg. The overall incidence of possible hypoglycemia (as defined above for the 14-week trial) for glimepiride versus placebo was 19.7% versus 3.2%. All of these events were self-treated.
Weight Gain: Glimepiride, like all sulfonylureas, can cause weight gain.
Allergic Reactions: In clinical trials, allergic reactions, such as pruritus, erythema, urticaria, and morbilliform or maculopapular eruptions, occurred in less than 1% of glimepiride-treated patients. These may resolve despite continued treatment with glimepiride. There are postmarketing reports of more serious allergic reactions (e.g., dyspnea, hypotension, shock) [see WARNINGS AND PRECAUTIONS].
Hematologic: Decreases in mean hemoglobin and hematocrit occurred in a dose-related fashion in adult patients treated with rosiglitazone (mean decreases in individual trials as much as 1.0 g/dL hemoglobin and as much as 3.3% hematocrit). The changes occurred primarily during the first 3 months following initiation of therapy with rosiglitazone or following a dose increase in rosiglitazone. The time course and magnitude of decreases were similar in patients treated with a combination of rosiglitazone and other hypoglycemic agents or monotherapy with rosiglitazone. White blood cell counts also decreased slightly in adult patients treated with rosiglitazone. Decreases in hematologic parameters may be related to increased plasma volume observed with treatment with rosiglitazone.
Serum Transaminase Levels: In pre-approval clinical trials in 4,598 patients treated with rosiglitazone encompassing approximately 3,600 patient-years of exposure, there was no evidence of drug-induced hepatotoxicity.
In pre-approval controlled trials, 0.2% of patients treated with rosiglitazone had reversible elevations in ALT > 3X the upper limit of normal compared with 0.2% on placebo and 0.5% on active comparators. The ALT elevations in patients treated with rosiglitazone were reversible. Hyperbilirubinemia was found in 0.3% of patients treated with rosiglitazone compared with 0.9% treated with placebo and 1% in patients treated with active comparators. In pre-approval clinical trials, there were no cases of idiosyncratic drug reactions leading to hepatic failure. [See WARNINGS AND PRECAUTIONS]
In the 4- to 6-year ADOPT trial, patients treated with rosiglitazone (4,954 patient-years exposure), glyburide (4,244 patient-years exposure), or metformin (4,906 patient-years exposure) as monotherapy had the same rate of ALT increase to > 3X upper limit of normal (0.3 per 100 patient-years exposure).
In the RECORD trial, patients randomized to rosiglitazone in addition to metformin or sulfonylurea (10,849 patient-years exposure) and to metformin plus sulfonylurea (10,209 patient-years exposure) had a rate of ALT increase to ≥ 3X upper limit of normal of approximately 0.2 and 0.3 per 100 patient-years exposure, respectively.
Glimepiride: Serum Transaminase Levels: In 11 pooled, placebo-controlled trials of glimepiride, 1.9% of glimepiride-treated patients and 0.8% of placebo-treated patients developed serum ALT > 2X the upper limit of the reference range.
In addition to adverse reactions reported from clinical trials, the events described below have been identified during post-approval use of AVANDARYL or its individual components. Because these events are reported voluntarily from a population of unknown size, it is not possible to reliably estimate their frequency or to always establish a causal relationship to drug exposure.
Rosiglitazone: In patients receiving thiazolidinedione therapy, serious adverse events with or without a fatal outcome, potentially related to volume expansion (e.g., congestive heart failure, pulmonary edema, and pleural effusions) have been reported [see BOXED WARNING, WARNINGS AND PRECAUTIONS].
There are postmarketing reports with rosiglitazone of hepatitis, hepatic enzyme elevations to 3 or more times the upper limit of normal, and hepatic failure with and without fatal outcome, although causality has not been established.
There are postmarketing reports with rosiglitazone of rash, pruritus, urticaria, angioedema, anaphylactic reaction, Stevens-Johnson syndrome [see CONTRAINDICATIONS], and new onset or worsening diabetic macular edema with decreased visual acuity [see WARNINGS AND PRECAUTIONS].
- Serious hypersensitivity reactions, including anaphylaxis, angioedema, and Stevens-Johnson syndrome [see WARNINGS AND PRECAUTIONS]
- Hemolytic anemia in patients with and without G6PD deficiency [see WARNINGS AND PRECAUTIONS]
- Impairment of liver function (e.g., with cholestasis and jaundice), as well as hepatitis, which may progress to liver failure
- Porphyria cutanea tarda, photosensitivity reactions, and allergic vasculitis
- Leukopenia, agranulocytosis, aplastic anemia, and pancytopenia
- Thrombocytopenia (including severe cases with platelet count less than 10,000/μL) and thrombocytopenic purpura
- Hepatic porphyria reactions and disulfiram-like reactions
- Hyponatremia and syndrome of inappropriate antidiuretic hormone secretion (SIADH), most often in patients who are on other medications or who have medical conditions known to cause hyponatremia or increase release of antidiuretic hormone
