What is ramelteon?

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

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

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

Warnings

Before taking Rozerem, tell your doctor if you have liver disease, sleep apnea, a breathing disorder such as chronic obstructive pulmonary disease, or a history of depression, mental illness, or suicidal thoughts.

You should not use Rozerem if you are also taking fluvoxamine (Luvox), or if you have ever had a severe allergic reaction to ramelteon.

Rozerem may cause a severe allergic reaction. Get emergency medical help if you have hives; difficult breathing; nausea and vomiting; swelling of your face, lips, tongue, or throat.

Take Rozerem 30 minutes before your normal bedtime. After you take this medicine, avoid doing anything other than getting ready for bed.

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

Some people using this medicine have engaged in activity while not fully awake and later had no memory of it. If this happens to you, call your doctor right away.

Before taking this medicine

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

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

• you have severe liver disease; or

• you also take fluvoxamine.

To make sure this medicine is safe for you, tell your doctor if you have ever had:

• liver disease;

• breathing problems;

• sleep apnea (breathing stops while you are asleep); or

• depression, mental illness, or suicidal thoughts.

Tell your doctor if you are pregnant or breastfeeding.

You should not breastfeed within 25 hours after using Rozerem. If you use a breast pump during this time, throw out any milk you collect. Do not feed it to your 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.

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

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

Rozerem should not be taken with or after a high-fat meal. This will make it harder for your body to absorb the medication.

What other drugs will affect Rozerem?

Using Rozerem with other drugs that make you drowsy can worsen this effect. Ask your doctor before using opioid medication, a sleeping pill, a muscle relaxer, or medicine for anxiety or seizures.

Sometimes it is not safe to use certain medications at the same time. Some drugs can affect your blood levels of other drugs you take, which may increase side effects or make the medications less effective.

Other drugs may interact with ramelteon, including prescription and over-the-counter medicines, vitamins, and herbal products. Tell your doctor about all your current medicines and any medicine you start or stop using.
