Suvorexant is used treat insomnia (difficulty falling asleep or staying asleep). Suvorexant is in a class of medications called orexin receptor antagonists. It works by blocking the action of a certain natural substance in the brain that causes wakefulness.

Suvorexant comes as a tablet to take by mouth. It is usually taken once a day, if needed, no earlier than 30 minutes before bedtime. Suvorexant may be taken with or without food but will begin to work faster if taken on an empty stomach. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take suvorexant exactly as directed. Never take more than one dose of suvorexant per day even if you are still having trouble falling asleep or staying asleep.

You will probably become very sleepy soon after you take suvorexant and will remain sleepy for some time after you take the medication. Plan to go to bed right after you take the medication and to stay in bed for at least 7 hours. Do not take suvorexant if you will be unable to remain asleep for the required number of hours after taking the medication. If you get up too soon after taking suvorexant, you may experience drowsiness and difficulty driving or performing tasks that require alertness.

Your sleep problems should improve within 7 to 10 days after you start taking suvorexant. Call your doctor if your sleep problems do not improve during this time or if they get worse at any time during your treatment.

Your doctor will probably start you on a low dose of suvorexant and may gradually increase your dose if your insomnia does not improve. Your doctor may also decrease your dose of suvorexant or tell you to stop taking the medication if it makes you feel too drowsy during the day.

Swallow the tablets whole; do not split, chew, or crush them.

Suvorexant may be habit forming. Do not take a larger dose, take it more often, or take it for a longer period of time than prescribed by your doctor.
