View full FDA label ↗
Ramelteon is a medication used to help people who have trouble falling asleep, a condition known as insomnia. It works by acting on certain receptors in the brain that help regulate sleep. You should take it as a tablet, with a starting dose of 8 mg taken about 30 minutes before bedtime, and you should not exceed this dose in a day. It's important to avoid taking ramelteon with fluvoxamine, a medication that can significantly increase its effects, so they should not be used together. Additionally, if you have severe liver problems, you should not use this medication.
