What is the mechanism of action for Quviviq?

Quviviq is a dual orexin receptor antagonist (DORA) insomnia medicine for adults that works by blocking orexin receptors. Quviviq turns down overactive wakefulness by blocking orexins, which are chemical messengers in the brain that promote wakefulness. It may be prescribed if you have trouble falling or staying asleep.

How does Quviviq work for sleep?

Quviviq works in the hypothalamus, a part of the brain, by blocking the receptors OX1R and OX2R. The neuropeptides Orexin A and Orexin B bind to these receptors to promote a wakeful state. When Quviviq blocks these receptors, the neuropeptides cannot bind to their receptor sites, which helps with sleep.

Can I take Quviviq every night?

Unlike some drugs used for insomnia, you can take Quviviq (generic name: daridorexant) every night over the long-term if this is how your healthcare provider prescribes it, but don’t take more than prescribed.

Quviviq usually works within 30 minutes after you take it. It may take longer for it to work if you take it with or right after a meal. It works throughout the night and can help you fall asleep and stay asleep. Do not take this medicine unless you are able to stay in bed for at least 7 hours before you must get up and be active again.

People usually start to sleep better after about one week of treatment and continue to improve over that month. In studies, Quviviq helped people with insomnia sleep better for at least 3 months. Call your healthcare provider if your sleep worsens or is not improved within a week to 10 days.

It's important that you know in some cases your awareness or alertness may be decreased In the morning after taking Quviviq the night before. In some cases, you may feel drowsy for several days. This can be dangerous, especially if you need to drive, think clearly or perform other hazardous activities. You might feel sleepy during the day too. If this occurs, report these side effects to your doctor.

If you feel drowsy or unsteady in the morning, do not drive, operate machinery or perform other hazardous tasks.
