Suvorexant (suvorexant) — Uses, Dosage, Side Effects & Safety

Drug class: Orexin receptor antagonist (hypnotic)

Overview

Suvorexant is a prescription medication used to help adults who have trouble falling asleep or staying asleep, a condition known as insomnia. It works by blocking the action of orexin, a natural substance in the brain that promotes wakefulness. By reducing orexin activity, suvorexant helps you fall asleep faster and stay asleep longer. This medication is usually taken at bedtime and is intended for short-term use. It is not a cure for insomnia but can help manage symptoms when used as directed. Patients should use suvorexant only when they can get a full night's sleep (at least 7 hours) before they need to be active again. Key points: Suvorexant may cause drowsiness the next day, especially if not taken as prescribed. It should not be combined with alcohol or other sleep medications. Always follow your healthcare provider's instructions and discuss any concerns or side effects.
