Rozerem

Clinical summary

Indications and usage 1 INDICATIONS AND USAGE ROZEREM ® is indicated for the treatment of insomnia characterized by difficulty with sleep onset. The clinical trials performed in support of efficacy were up to six months in duration. The final formal assessments of sleep latency were performed after two days of treatment during the crossover study (elderly only), at five weeks in the six week studies (adults and elderly), and at the end of the six month study (adults and elderly) [see Clinical Studies (14) ] . ROZEREM is indicated for the treatment of insomnia characterized by difficulty with sleep onset. ( 1 ) Dosage and administration 2 DOSAGE AND ADMINISTRATION Adult dose: 8 mg taken within 30 minutes of going to bed. ( 2.1 ) Should not be taken with or immediately after a high-fat meal. ( 2.1 ) Total daily dose should not exceed 8 mg. ( 2.1 ) 2.1 Dosage in Adults The recommended dose of ROZEREM is 8 mg taken within 30 minutes of going to bed. It is recommended that ROZEREM not be taken with or immediately after a high-fat meal. The total ROZEREM dose should not exceed 8 mg per day. 2.2 Dosing in Patients with Hepatic Impairment ROZEREM is not recommended in patients with severe hepatic impairment. ROZEREM should be used with caution in patients with moderate hepatic impairment [see Warnings and Precautions (5.6) , Clinical Pharmacology (12.4) ] . 2.3 Administration with Other Medications ROZEREM should not be used in combination with fluvoxamine. ROZEREM should be used with caution in patients taking other CYP1A2 inhibiting drugs [see Drug Interactions (7) , Clinical Pharmacology (12.5) ]. Warnings and cautions 5 WARNINGS AND PRECAUTIONS Severe anaphylactic/anaphylactoid reactions: Angioedema and anaphylaxis have been reported. Do not rechallenge if such reactions occur. ( 5.1 ) Need to evaluate for comorbid diagnoses: Reevaluate if insomnia persists after 7 to 10 days of treatment. ( 5.2 ) Abnormal thinking, behavioral changes, complex behaviors: May include "sleep-driving" and hallucinations. Immediately evaluate any new onset behavioral changes. ( 5.3 ) Depression: Worsening of depression or suicidal thinking may occur. ( 5.3 ) CNS effects: Potential impairment of activities requiring complete mental alertness such as operating machinery or driving a motor vehicle, after ingesting the drug. ( 5.4 ) Reproductive effects: Include decreased testosterone and increased prolactin levels. Effect on reproductive axis in developing humans is unknown. ( 5.5 ) Patients with severe sleep apnea: ROZEREM is not recommended for use in this population. ( 5.6 ) 5.1 Severe Anaphylactic and Anaphylactoid Reactions Rare cases of angioedema involving the tongue, glottis or larynx have been reported in patients after taking the first or subsequent doses of ROZEREM. Some patients have had additional symptoms such as dyspnea, throat closing, or nausea and vomiting that suggest anaphylaxis. Some patients have required medical therapy in the emergency department. If angioedema involves the tongue, glottis or larynx, airway obstruction may occur and be fatal. Patients who develop angioedema after treatment with ROZEREM should not be rechallenged with the drug. 5.2 Need to Evaluate for Comorbid Diagnoses Since sleep disturbances may be the presenting manifestation of a physical and/or psychiatric disorder, symptomatic treatment of insomnia should be initiated only after a careful evaluation of the patient. The failure of insomnia to remit after 7 to 10 days of treatment may indicate the presence of a primary psychiatric and/or medical illness that should be evaluated. Worsening of insomnia, or the emergence of new cognitive or behavioral abnormalities, may be the result of an unrecognized underlying psychiatric or physical disorder and requires further evaluation of the patient. Exacerbation of insomnia and emergence of cognitive and behavioral abnormalities were seen with ROZEREM during the clinical development program . 5.3 Abnormal Thinking and Behavioral Changes A variety of cognitive and behavior changes have been reported to occur in association with the use of hypnotics. In primarily depressed patients, worsening of depression (including suicidal ideation and completed suicides) has been reported in association with the use of hypnotics. Hallucinations, as well as behavioral changes such as bizarre behavior, agitation and mania have been reported with ROZEREM use. Amnesia, anxiety and other neuro-psychiatric symptoms may also occur unpredictably. Complex behaviors such as "sleep-driving" (i.e., driving while not fully awake after ingestion of a hypnotic) and other complex behaviors (e.g., preparing and eating food, making phone calls, or having sex), with amnesia for the event, have been reported in association with hypnotic use. The use of alcohol and other CNS depressants may increase the risk of such behaviors. These events can occur in hypnotic-naive as well as in hypnotic-experienced persons. Complex behaviors have
