What is Quviviq (daridorexant)?
Quviviq contains daridorexant, a sedative-hypnotic as the active ingredient. Daridorexant is a dual orexin receptor antagonist. It works by blocking the action of the neuropeptide orexin, a chemical produced by the brain that promotes wakefulness. This allows people to fall asleep quicker, stay asleep for longer, and to improve functioning during the day.
Is Quviviq addictive?
Quviviq may cause addiction, especially if you have a substance use disorder. Discuss your treatment plan with your doctor to ensure you take this medication safely.
Is Quviviq a narcotic?
Quviviq is not a narcotic. It belongs to a class of drugs called dual orexin receptor antagonists (DORAs). However, Quviviq is a federally controlled substance as it can be abused and lead to addiction.
Is Quviviq safe?
Quviviq may affect your ability to drive safely and think clearly. Speak to your doctor to discuss the side effects of Quviviq and how to take it safely.
What is the safest sleeping pill for the elderly?
First-line treatment in the elderly is nonbenzodiazepines (such as zolpidem and zaleplon). These are safer than older treatments such as antihistamines, tricyclic antidepressants, and benzodiazepines.
