Complete adverse effect profile including incidence rates and management
Important Safety Information
This is not a complete list of all possible side effects. Contact your healthcare provider if you experience any unexpected symptoms. For serious or life-threatening side effects, seek emergency medical attention immediately.
6 ADVERSE REACTIONS The following serious adverse reactions are discussed in greater detail in other sections: CNS Depressant Effects and Daytime Impairment [see Warnings and Precautions (5.1) ] Worsening of Depression/Suicidal Ideation [see Warnings and Precautions (5.2) ] Complex Sleep Behaviors [see Warnings and Precautions (5.3) ] Sleep Paralysis, Hypnagogic/Hypnopompic Hallucinations, Cataplexy-Like Symptoms [see Warnings and Precautions (5.4) ] Patients with Compromised Respiratory Function [see Warnings and Precautions (5.5) ] The most common adverse reaction (reported in 5% or more of patients treated with BELSOMRA and at least twice the placebo rate) with BELSOMRA was somnolence ( 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 clinical practice.
In 3-month controlled efficacy trials (Study 1 and Study 2), 1263 patients were exposed to BELSOMRA including 493 patients who received BELSOMRA 15 mg or 20 mg (see Table 1 ).
In a long-term study, additional patients (n=521) were treated with BELSOMRA at higher than recommended doses, including a total of 160 patients who received BELSOMRA for at least one year.
Table 1: Patient Exposure to BELSOMRA 15 mg or 20 mg in Study 1 and Study 2 Patients Treated BELSOMRA 15 mg BELSOMRA 20 mg For ≥ 1 Day (n) 202 291 Men (n) 69 105 Women (n) 133 186 Mean Age (years) 70 45 For ≥ 3 Months (n) 118 172 The pooled safety data described below (see Table 2 ) reflect the adverse reaction profile during the first 3 months of treatment.
Adverse Reactions Resulting in Discontinuation of Treatment The incidence of discontinuation due to adverse reactions for patients treated with 15 mg or 20 mg of BELSOMRA was 3% compared to 5% for placebo.
No individual adverse reaction led to discontinuation at an incidence ≥1%.
Most Common Adverse Reactions In clinical trials of patients with insomnia treated with BELSOMRA 15 mg or 20 mg, the most common adverse reaction (reported in 5% or more of patients treated with BELSOMRA and at least twice the placebo rate) was somnolence (BELSOMRA 7%;
placebo 3%).
5 WARNINGS AND PRECAUTIONS CNS Depressant Effects and Daytime Impairment: Risk of impaired alertness and motor coordination, including impaired driving;
risk increases with dose;
caution patients taking 20 mg against next-day driving and other activities requiring complete mental alertness ( 5.1 ).
Worsening of Depression/Suicidal Ideation: Worsening of depression or suicidal thinking may occur.
Risk increases with dose.
Like all medications, Belsomra can cause side effects. However, not everyone who takes this medication will experience them. Many side effects are dose-dependent and may improve as your body adjusts to the medication. Others may require dose adjustment or medical attention.
