Adverse Reactions
6 ADVERSE REACTIONS The most frequently occurring adverse reactions (≥ 5% and greater than placebo) were nausea, headache, constipation, dizziness, insomnia, hot flush, hyperhidrosis, vomiting, palpitations, heart rate increased, dry mouth, and hypertension ( 6.1 ).

6.1 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.
Patient Exposure Milnacipran hydrochloride was evaluated in three double-blind placebo-controlled trials involving 2209 fibromyalgia patients (1557 patients treated with milnacipran hydrochloride and 652 patients treated with placebo) for a treatment period up to 29 weeks.
The stated frequencies of adverse reactions represent the proportion of individuals who experienced, at least once, a 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 Leading to Discontinuation In placebo-controlled trials in patients with fibromyalgia, 23% of patients treated with milnacipran hydrochloride 100 mg/day, 26% of patients treated with milnacipran hydrochloride 200 mg/day discontinued prematurely due to adverse reactions, compared to 12% of patients treated with placebo.
The adverse reactions that led to withdrawal in ≥ 1% of patients in the milnacipran hydrochloride treatment group and with an incidence rate greater than that in the placebo treatment group were nausea (milnacipran 6%, placebo 1%), palpitations (milnacipran 3%, placebo 1%), headache (milnacipran 2%, placebo 0%), constipation (milnacipran 1%, placebo 0%), heart rate increased (milnacipran 1%, placebo 0%), hyperhidrosis (milnacipran 1%, placebo 0%), vomiting (milnacipran 1%, placebo 0%), and dizziness (milnacipran 1% and placebo 0.5%).
Discontinuation due to adverse reactions was generally more common among patients treated with milnacipran hydrochloride 200 mg/day compared to milnacipran hydrochloride 100 mg/day.
Most Common Adverse Reactions in Placebo Controlled Trials In the placebo-controlled fibromyalgia patient trials, the most frequently occurring adverse reaction in clinical trials was nausea.
The most common adverse reactions (incidence ≥ 5% and twice placebo) in patients treated with milnacipran hydrochloride were constipation, hot flush, hyperhidrosis, vomiting, palpitations, heart rate increased, dry mouth, and hypertension.
Table 4 lists all adverse reactions that occurred in at least 2% of patients treated with milnacipran hydrochloride at either 100 or 200 mg/day and at an incidence greater than that of placebo.

Genitourinary Adverse Reactions in Males In the placebo-controlled fibromyalgia studies, the following treatment-emergent adverse reactions related to the genitourinary system were observed in at least 2% of male patients treated with milnacipran hydrochloride, and occurred at a rate greater than in placebo-treated male patients: dysuria, ejaculation disorder, erectile dysfunction, ejaculation failure, libido decreased, prostatitis, scrotal pain, testicular pain, testicular swelling, urinary hesitation, urinary retention, urethral pain, and urine flow decreased.
Other Adverse Reactions Observed During Clinical Trials of Milnacipran hydrochloride in Fibromyalgia Following is a list of frequent (those occurring on one or more occasions in at least 1/100 patients) treatment-emergent adverse reactions reported from 1824 fibromyalgia patients treated with milnacipran hydrochloride for periods up to 68 weeks.
The listing does not include those events already listed in Table 4 , those events for which a drug cause was remote, those events which were so general as to be uninformative, and those events reported only once which did not have a substantial probability of being acutely life threatening.
Adverse reactions are categorized by body system and listed in order of decreasing frequency.
Adverse reactions of major clinical importance are described in the Warnings and Precautions section ( 5 ) .
Gastrointestinal Disorders ― diarrhea, dyspepsia, gastroesophageal reflux disease, flatulence, abdominal distension General Disorders ― fatigue, peripheral edema, irritability, pyrexia Infections ― urinary tract infection, cystitis Injury, Poisoning, and Procedural Complications ― contusion, fall Investigations ― weight decreased or increased Metabolism and Nutrition Disorders ― hypercholesterolemia Nervous System Disorders ― somnolence, dysgeusia Psychiatric Disorders ― depression, stress Skin Disorders ― night sweats 6.2 Postmarketing Experience The following additional adverse reactions have been identified from spontaneous reports of milnacipran hydrochloride received worldwide.
These adverse reactions have been chosen for inclusion because of a combination of seriousness, frequency of reporting, or potential causal connection to milnacipran hydrochloride.
However, because these adverse reactions were 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.
These events include: Blood and Lymphatic System Disorders ― leukopenia, neutropenia, thrombocytopenia Cardiac Disorders ― supraventricular tachycardia, Takotsubo cardiomyopathy Eye Disorders ― accommodation disorder Endocrine Disorders ― hyperprolactinemia Gastrointestinal Disorders ― acute pancreatitis Hepatobiliary Disorders ― hepatitis Metabolism and Nutrition Disorders ― anorexia, hyponatremia Musculoskeletal and Connective Tissue Disorders ― rhabdomyolysis Nervous System Disorders ― anosmia, convulsions (including grand mal), hyposmia, loss of consciousness, Parkinsonism Psychiatric Disorders ― aggression, anger, delirium, hallucination, homicidal ideation Renal and Urinary Disorders ― acute renal failure Reproductive System and Breast Disorders ― galactorrhea, decreased libido, delayed or absent orgasm Skin Disorders ― erythema multiforme, Stevens Johnson syndrome Vascular Disorders ― hypertensive crisis
