gov/medwatch. 1 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, one treatment-emergent adverse reaction of the type listed. A reaction was considered treatment-emergent if it occurred for the first time or worsened while receiving therapy following baseline evaluation.
Adverse Reactions in Adults Adult Clinical Trial Database The data described below reflect exposure to duloxetine in placebo-controlled adult trials for MDD (N=3779), GAD (N=1018), OA (N=503), CLBP (N=600), DPNP (N=906), and FM (N=1294).
The age range in this pooled population was 17 to 89 years of age. In this pooled population, 66%, 61%, 61%, 43%, and 94% of adult patients were female; and 82%, 73%, 85%, 74%, and 86% of adult patients were Caucasian in the MDD, GAD, OA and CLBP, DPNP, and FM populations, respectively.
Most patients received Duloxetine delayed-release capsules dosages of a total of 60 to 120 mg per day [see Clinical Studies (14) ] . 3) ] ; however, the adverse reactions observed in this geriatric population were generally similar to adverse reactions in the overall adult population.

2 1 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.
2) ]. 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 a baseline level of dysfunction, which is commonly seen in depressed patients. In these trials, Duloxetine delayed-release capsules-treated male patients experienced significantly more sexual dysfunction, as measured by the total score on the ASEX and the ability to reach orgasm, than placebo-treated male patients (see Table 5 ).
Duloxetine delayed-release capsules- treated female patients did not experience more sexual dysfunction than placebo-treated female patients as measured by ASEX total score. Healthcare providers should routinely inquire about possible sexual adverse reactions in Duloxetine delayed-release capsules-treated patients.

Adverse Reactions Observed in Placebo-Controlled Clinical Trials in Pediatric Patients Pediatric Clinical Trial Database The data described below reflect exposure to duloxetine (N=567) in pediatric patients aged 7 to 18 years of age from two 10-week, placebo-controlled trials in patients with MDD (N=341) (Studies MDD-6 and MDD-7), one 10-week placebo- controlled trial in GAD (N=135) (Study GAD-6), and a 13-week trial in fibromyalgia (N=91).
4) ] . Of the duloxetine-treated patients in these studies, 36% were 7 to 11 years of age (64% were between 12 to 18 years old), 55% were female, and 69% were Caucasian. Patients received 30 to 120 mg of Duloxetine delayed-release capsules per day during placebo-controlled acute treatment studies.
In the pediatric MDD, GAD, and fibromyalgia trials up to 40 weeks long, there were 988 duloxetine-treated pediatric patients aged 7 to 17 years of age (most patients received 30-120 mg per day) – 35% were 7 to 11 years of age (65% were 12 to 17 years old) and 56% were female.
Most Common Adverse Reactions in Pediatric Trials The most common adverse reactions (≥5% in duloxetine-treated patients and at least twice the incidence of placebo- treated patients) in all pooled pediatric populations (MDD, GAD, and fibromyalgia) were decreased weight, decreased appetite, nausea, vomiting, fatigue, and diarrhea.
Adverse Reactions in Pediatric Patients Aged 7 to 17 Years Old with MDD and GAD The adverse reaction profile observed in clinical trials in pediatric patients aged 7 to 18 years old with MDD and GAD was consistent with the adverse reaction profile observed in adult clinical trials.
The most common (≥5% and twice placebo) adverse reactions observed in these pediatric clinical trials included: nausea, diarrhea, decreased weight, and dizziness. 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 patients treated with placebo.
