What is Quviviq?
Quviviq (generic name: daridorexant) is a prescription medication used to treat insomnia in adults. It helps people who have difficulty falling asleep or staying asleep throughout the night.
Unlike traditional sleep medications, Quviviq belongs to a class called orexin receptor antagonists, which work by targeting the brain’s wakefulness system instead of directly sedating the body.
How Does Quviviq Work?
Quviviq works by blocking orexin, a natural chemical in the brain that promotes wakefulness. By reducing orexin activity, the medication helps the brain transition into sleep more easily and maintain sleep for longer periods.
This targeted mechanism helps:
- Reduce nighttime awakenings
- Improve total sleep time
- Support natural sleep cycles without heavy sedation
Uses of Quviviq
Quviviq is primarily prescribed for:
- Chronic insomnia in adults
- Difficulty falling asleep (sleep onset insomnia)

- Common starting dose: 25 mg or 50 mg once daily
