Ramelteon

Ramelteon is used to help patients who have sleep-onset insomnia (difficulty falling asleep) fall asleep more quickly. Ramelteon is in a class of medications called melatonin receptor agonists. It works similarly to melatonin, a natural substance in the brain that is needed for sleep.

🔔 How should this medicine be used?

Ramelteon comes as a tablet to take by mouth. It is usually taken once a day, no earlier than 30 minutes before bedtime. Do not take ramelteon with or shortly after a meal. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take ramelteon exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

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

You may become sleepy soon after you take ramelteon. After you take ramelteon, you should complete any necessary bedtime preparations and go to bed. Do not plan any other activities for this time. Do not take ramelteon if you will be unable to remain asleep for 7 to 8 hours after taking the medication.

Your insomnia should improve within 7 to 10 days after you begin treatment with ramelteon. Call your doctor if your insomnia does not improve during this time or gets worse at any time during your treatment.

Your doctor or pharmacist will give you the manufacturer’s patient information sheet (Medication Guide) when you begin treatment with ramelteon and each time you refill your prescription. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website (http://www.fda.gov/Drugs) or the manufacturer’s website to obtain the Medication Guide.

Students who make it into medical school pay a lot of money for the privilege of eventually becoming a doctor, with medical school students in the class of 2019 graduating with an average of $201,490 in student debt, according to the Association of American Medical Colleges as reported by Nerd Wallet. That’s an increase of 2.5% from 2018.

Call your doctor right away if you find out that you have been driving or doing anything else unusual while you were sleeping.
