What is ramelteon?

Ramelteon is a sedative, also called a hypnotic. It works by affecting certain substances in your body that help regulate your "sleep-wake cycle."

Ramelteon is used to treat insomnia that is associated with having trouble falling asleep.

Unlike some other sleep medications, ramelteon is not known to be habit-forming.

Ramelteon may also be used for purposes not listed in this medication guide.

Important Information

You should not use ramelteon if you are also taking fluvoxamine (Luvox), or if you have severe liver disease.

Before taking this medicine

Ramelteon will make you fall asleep. Never take ramelteon during your normal waking hours, unless you have at least 7 to 8 hours to dedicate to sleeping.

You should not use ramelteon if you are allergic to it, or if:

  • you have severe liver disease; or

  • you also take fluvoxamine (Luvox).

To make sure ramelteon is safe for you, tell your doctor if you have:

It is not known whether this medicine will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant.

It is not known whether ramelteon passes into breast milk or if it could harm a nursing baby. Tell your doctor if you are breast-feeding a baby.

Ramelteon may affect the levels of male or female hormones (testosterone or prolactin). This may affect menstrual periods in women, sexual desire in men, or fertility (ability to have children) in either a man or a woman.

Ramelteon is not approved for use by anyone younger than 18 years old.

How should I take ramelteon?

Do not crush, chew, or break the tablet. Swallow it whole.

Avoid taking ramelteon together with or just after eating a high-fat meal. This will make it harder for your body to absorb the medication.

Call your doctor if your symptoms do not improve after 7 to 10 days of using ramelteon.

Store at room temperature away from moisture and heat. Keep the bottle tightly closed when not in use.

What happens if I miss a dose?

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
