Taking BELSOMRA

Finding the right dose

The Recommended Dose of BELSOMRA® (suvorexant) C-IV is 10 mg

The recommended dose is 10 mg.*

*5 mg is the recommended dose for certain patients, and these patients should generally not exceed 10 mg.

Your insomnia is as individual as you are, and medicines work differently for different people, so BELSOMRA comes in multiple strengths.

Tell your doctor if you’re still not sleeping well with 10 mg.* If your current dose is well tolerated and you’re not getting the sleep you want, your doctor may suggest that you increase your dose. Do not take more than 20 mg of BELSOMRA in 1 day.
