Quviviq is FDA-approved for the treatment of insomnia in adults, characterized by difficulties with sleep onset and/or sleep maintenance.
Quviviq is an orexin receptor antagonist that works by blocking the activity of orexin (hypocretin), a neurotransmitter that promotes wakefulness. By inhibiting orexin signaling, it helps facilitate the transition to sleep.
Quviviq may cause drowsiness and impair next-day activities; patients should only take it when they can dedicate at least 7 hours to sleep. Common side effects include headache, somnolence, and fatigue. It is contraindicated in patients with narcolepy. Avoid alcohol and other CNS depressants while taking this medication.
