Clinical Trials 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 to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

The stated frequencies of adverse reactions represent the proportion of patients who experienced, at least once, a treatment-emergent adverse reaction of the type listed.

Adverse ReactionsIn Adults

The data described below reflect exposure to duloxetine delayed-release capsules in placebo-controlled trials for MDD (N = 3779), GAD (N = 1018), OA (N = 503), CLBP (N = 600), and DPNP (N = 906), and FM (N = 1294). The population studied was 17 to 89 years of age; 65.7%, 60.8%, 60.6%, 42.9%, and 94.4% female; and 81.8%, 72.6%, 85.3%, 74.0%, and 85.7% Caucasian for MDD, GAD, OA and CLBP, DPNP, and FM, respectively. Most patients received doses of a total of 60 to 120 mg per day [see Clinical Studies].The data below do not include results of the trial examining the efficacy of duloxetine delayed-release in patients ≥ 65 years old for the treatment of generalized anxiety disorder; however, the adverse reactions observed in this geriatric sample were generally similar to adverse reactions in the overall adult population.

Effects on Male and Female Sexual Function in Adults with MDD

Changes in sexual desire, sexual performance and sexual satisfaction often occur as manifestations of psychiatric disorders or diabetes, but they may also be a consequence of pharmacologic treatment. Because adverse sexual reactions are presumed to be voluntarily underreported, the Arizona Sexual Experience Scale (ASEX), a validated measure designed to identify sexual side effects, was used prospectively in 4 MDD placebo-controlled adult trials [see Clinical Studies]. The ASEX scale includes five questions that pertain to the following aspects of sexual function: 1) sex drive, 2) ease of arousal, 3) ability to achieve erection (men) or lubrication (women), 4) ease of reaching orgasm, and 5) orgasm satisfaction. Positive numbers signify a worsening of sexual function from baseline. Negative numbers signify an improvement from baseline level of sexual dysfunction from baseline, which is commonly seen in depressed patients.

In these trials, male patients treated with duloxetine delayed-release capsules experienced significantly more sexual dysfunction, as measured by the total score on the ASEX and the ability to reach orgasm, than did placebo-treated male patients (see Table 5). Female patients treated with duloxetine delayed-release capsules did not experience more sexual dysfunction than on placebo-treated female patients as measured by ASEX total score. Healthcare providers should routinely inquire about possible sexual adverse reactions in patients treated with duloxetine delayed-release capsules.

Vital Sign Changes in Adults

In placebo-controlled clinical trials across approved adult populations for change from baseline to endpoint, duloxetine delayed-release capsules-treated patients had mean increases of 0.23 mm Hg in systolic blood pressure (SBP) and 0.73 mm Hg in diastolic blood pressure (DBP) compared to mean decreases of 1.09 mm Hg SBP and 0.55 mm Hg in DBP placebo-treated patients. There was no significant difference in the frequency of sustained (3 consecutive visits) elevated blood pressure [see WARNINGS AND PRECAUTIONS].

Duloxetine delayed-release capsules treatment, for up to 26 weeks in placebo-controlled trials across approved adult populations, typically caused a small increase in heart rate for change from baseline to endpoint compared to placebo of up to 1.37 beats per minute (increase of 1.20 beats per minute in duloxetine delayed-release capsules-treated patients, decrease of 0.17 beats per minute in placebo-treated patients).

Laboratory Changes in Adults

Duloxetine delayed-release capsules treatment in placebo-controlled clinical trials across approved adult populations, was associated with small mean increases from baseline to endpoint in ALT, AST, CPK, and alkaline phosphatase; infrequent, modest, transient, abnormal values were observed for these analytes in duloxetine delayed-release capsules-treated patients when compared with placebo-treated patients [see WARNINGS AND PRECAUTIONS]. High bicarbonate, cholesterol, and abnormal (high or low) potassium, were observed more frequently in duloxetine delayed-release capsules treated patients compared to placebo-treated patients.

Other Adverse Reactions Observed During the Premarketing and Postmarketing Clinical Trial Evaluation of Duloxetine Delayed-Release Capsules in Adults

Following is a list of adverse reactions reported by patients treated with duloxetine delayed-release capsules in clinical trials. In clinical trials of all approved adult populations, 34,756 patients were treated with duloxetine delayed-release capsules. Of these, 26.9% (9337) took duloxetine delayed-release capsules for at least 6 months, and 12% (4317) for at least one year.

Adverse Reactions Observed In Placebo-Controlled Clinical Trials In Pediatric Patients

The data described below reflect exposure to duloxetine delayed-release capsules in pediatric, 10 week, placebo-controlled trials for MDD (N = 341) and GAD (N = 135). The population studied (N = 476) was 7 to 17 years of age with 42.4% children age 7 to 11 years of age, 50.6% female, and 68.6% white. Patients received 30 to 120 mg per day during placebo-controlled acute treatment studies. Additional data come from the overall total of 822 pediatric patients (age 7 to 17 years of age) with 41.7% children age 7 to 11 years of age and 51.8% female exposed to duloxetine delayed-release capsules in MDD and GAD clinical trials up to 36 weeks in length, in which most patients received 30 to 120 mg per day. The safety and effectiveness of DRIZALMA SPRINKLE have not been established in pediatric patients with major depressive disorder (MDD), diabetic peripheral neuropathic pain, or chronic musculoskeletal pain.

Pediatric Clinical Trial Database

The adverse drug reaction profile observed in pediatric clinical trials in pediatric patients aged 7 to 17 years old was consistent with the adverse drug reaction profile observed in adult clinical trials. The specific adverse drug reactions observed in adult patients can be expected to be observed in pediatric patients [see Clinical Trials Experience]. The most common (≥5% and twice placebo) adverse reactions observed in pediatric clinical trials include: nausea, diarrhea, decreased weight, and dizziness.

Adverse Reactions in Pediatric Patients Aged 7 to 17 Years Old with MDD and GAD

Table 6 provides the incidence of adverse reactions in MDD and GAD pediatric placebo-controlled trials that occurred in greater than 2% of patients treated with duloxetine delayed-release capsules and with an incidence greater than placebo. DRIZALMA SPRINKLE is not approved for the treatment of MDD in pediatric patients [see Use In Specific Populations]

Other adverse reactions that occurred at an incidence of less than 2% and were reported by more duloxetine delayed-release capsules treated patients than placebo treated patients in pediatric MDD and GAD clinical trials included abnormal dreams (including nightmare), anxiety, flushing (including hot flush), hyperhidrosis, palpitations, pulse increased, and tremor (DRIZALMA SPRINKLE is not approved for the treatment of pediatric MDD).

The most commonly reported symptoms following discontinuation of duloxetine delayed-release capsules in pediatric clinical trials have included headache, dizziness, insomnia, and abdominal pain [see WARNINGS AND PRECAUTIONS].

Growth (Height and Weight) in Pediatric Patients 7 to 17 Years Old with GAD and MDD

Decreased appetite and weight loss have been observed in association with the use of SSRIs and SNRIs. Pediatric patients treated with duloxetine delayed-release capsules in clinical trials experienced a 0.1kg mean decrease in weight at 10 weeks, compared with a mean weight gain of approximately 0.9 kg in placebo-treated patients. The proportion of patients who experienced a clinically significant decrease in weight (≥3.5%) was greater in the duloxetine delayed-release capsules group than in the placebo group (16% and 6%, respectively). Subsequently, over the 4-to 6-month uncontrolled extension periods, duloxetine delayed-release capsules-treated patients on average trended toward recovery to their expected baseline weight percentile based on population data from age-and sex-matched peers.

In studies up to 9 months, duloxetine delayed-release capsules-treated pediatric patients experienced an increase in height of 1.7 cm on average (2.2 cm increase in patients [7 to 11 years of age] and 1.3 cm increase in patients [12 to 17 years of age]). While height increase was observed during these studies, a mean decrease of 1% in height percentile was observed (decrease of 2% in patients [7 to 11 years of age] and increase of 0.3% in patients [12 to 17 years of age]). Weight and height should be monitored regularly in pediatric patients treated with DRIZALMA SPRINKLE.

Postmarketing Experience

The following adverse reactions have been identified during post approval use of duloxetine delayed-release capsules. 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.

Adverse reactions reported since market introduction that were temporally related to duloxetine delayed-release capsules therapy and not mentioned elsewhere in labeling include: acute pancreatitis, anaphylactic reaction, aggression and anger (particularly early in treatment or after treatment discontinuation), angioneurotic edema, angle-closure glaucoma, colitis (microscopic or unspecified), cutaneous vasculitis (sometimes associated with systemic involvement), extrapyramidal disorder, galactorrhea, gynecological bleeding, hallucinations, hyperglycemia, hyperprolactinemia, hypersensitivity, hypertensive crisis, muscle spasm, rash, restless legs syndrome, seizures upon treatment discontinuation, supraventricular arrhythmia, tinnitus (upon treatment discontinuation), trismus, and urticaria.

DRUG INTERACTIONS

Drugs Having Clinically Important Interactions With DRIZALMA SPRINKLE

Table 7: Clinically Important Drug Interactions

Monoamine Oxidase Inhibitors (MAOIs)
Clinical Impact Concomitant use of SSRIs and SNRIs including duloxetine with MAOIs increases the risk of serotonin syndrome.
Intervention
  • The use of MAOIs intended to treat psychiatric disorders with duloxetine or within 5 days of stopping treatment with duloxetine is contraindicated [see CONTRAINDICATIONS and WARNINGS AND PRECAUTIONS].
  • The use of duloxetine delayed-release capsules within 14 days of stopping an MAOI intended to treat psychiatric disorders is also contraindicated [see CONTRAINDICATIONS and WARNINGS AND PRECAUTIONS].
  • Starting duloxetine in a patient who is being treated with MAOIs is also contraindicated [seeDOSAGE AND ADMINISTRATION, CONTRAINDICATIONS, WARNINGS AND PRECAUTIONS].
Examples Selegiline, tranylcypromine, isocarboxazid, phenelzine, linezolid, intravenous methylene blue
Serotonergic Drugs
Clinical Impact Concomitant use of duloxetine with other serotonergic drugs increases the risk of serotonin syndrome.
Intervention
  • Patients should be made aware of a potential increased risk for serotonin syndrome, particularly during treatment initiation and dose increases.
  • Monitor for symptoms of serotonin syndrome when duloxetine is used concomitantly with other drugs that may affect the serotonergic neurotransmitter systems.
  • Treatment with duloxetine delayed-release capsules and any concomitant serotonergic agents, should be discontinued immediately if the above events occur and supportive symptomatic treatment should be initiated [see WARNINGS AND PRECAUTIONS].
Examples Triptans, tricyclic antidepressants, fentanyl, lithium, tramadol, tryptophan, buspirone, amphetamines, other SNRIs or SSRIs, and St. John’s Wort
Inhibitors of CYP1A2
Clinical Impact Concomitant use of duloxetine with CYP1A2 inhibitors increases AUC, Cmax, t1/2 of duloxetine.
Intervention Avoid concomitant use of duloxetine delayed-release capsules with potent CYP1A2 inhibitors [see WARNINGS AND PRECAUTIONS, CLINICAL PHARMACOLOGY].
Examples Fluvoxamine, cimetidine, ciprofloxacin, enoxacin
Dual Inhibition of CYP1A2 and CYP2D6
Clinical Impact Concomitant administration of duloxetine with potent CYP1A2 inhibitors to CYP2D6 poor metabolizers results in increased AUC and Cmax of duloxetine.
Intervention Avoid co-administration of duloxetine delayed-release capsules and potent CYP1A2 inhibitors to CYP2D6 poor metabolizers [see CLINICAL PHARMACOLOGY].
Examples Fluvoxamine, cimetidine, ciprofloxacin, enoxacin
Drugs that Interfere with Hemostasis
Clinical Impact Concomitant use of duloxetine with an antiplatelet or anticoagulant drug may potentiate the risk of bleeding.
Intervention Closely monitor for bleeding for patients receiving an antiplatelet or anticoagulant drug when duloxetine is initiated or discontinued [WARNINGS AND PRECAUTIONS].
Examples NSAIDs, aspirin, warfarin
Inhibitors of CYP2D6
Clinical Impact Concomitant use of duloxetine with CYP2D6 inhibitors increase AUC of duloxetine. Greater degrees of inhibition are expected with higher doses of CYP2D6 inhibitors.
Intervention Exercise caution when co-administering duloxetine delayed-release capsules and potent CYP2D6 inhibitors [see WARNINGS AND PRECAUTIONS, CLINICAL PHARMACOLOGY].
Examples Paroxetine, fluoxetine, quinidine
Drugs Metabolized by CYP2D6
Clinical Impact Concomitant use of duloxetine increases AUC of a drug primarily metabolized by CYP2D6 which may increase the risk of toxicity of the CYP2D6 substrate drug.
Intervention Monitor plasma concentrations of CYP2D6 substrate and reduce dosage of CYP2D6 substrate drug if necessary [see WARNINGS AND PRECAUTIONS, CLINICAL PHARMACOLOGY].
Examples TCAs (nortriptyline, amitriptyline, imipramine, desipramine); phenothiazines (thioridazine); Type 1C antiarrhythmics (propafenone, flecainide)
Drugs that Affect Gastric Acidity
Clinical Impact In patients with conditions that may slow gastric emptying (e.g., some diabetics) and drugs that raise the gastrointestinal pH may lead to earlier the release of duloxetine.
Intervention Use with caution [see CLINICAL PHARMACOLOGY].
Examples Aluminum-and magnesium-containing antacids, famotidine, proton pump inhibitors
Drugs Metabolized by CYP1A2
Clinical Impact Concomitant use of duloxetine with CYP1A2 substrates may increase the AUC of CYP1A2 substrate.
Intervention Use with caution [see CLINICAL PHARMACOLOGY].
Examples Theophylline, caffeine
CNS Drugs
Clinical Impact Concomitant use of duloxetine with other centrally acting drugs may increase the CNS effects of duloxetine.
Intervention Use with caution [see WARNINGS AND PRECAUTIONS].
Examples Centrally acting CNS drugs
Drugs Highly Bound to Plasma Protein
Clinical Impact Concomitant use of duloxetine with highly protein bound drugs may cause increased free concentrations of the other drug, potentially resulting in adverse reactions.
Intervention Use with caution [see CLINICAL PHARMACOLOGY].
Examples Highly plasma protein binding drugs
Alcohol
Clinical Impact Concomitant use of duloxetine and alcohol may cause liver injury or aggravate pre-existing liver disease.
Intervention Avoid use patients with chronic liver disease or heavy alcohol use [see DOSAGE AND ADMINISTRATION, WARNINGS AND PRECAUTIONS].
