Warnings & Precautions

Persistent or Worsening Insomnia: 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.

  • Geriatric patients: Reduce starting dosage to 0.125 mg once daily. May increase to 0.25 mg if no response. Geriatric patients should not exceed 0.25 mg once daily
