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.
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 ( Web Site) or the manufacturer's website to obtain the Medication Guide.
This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.

Be sure to mention any of the following: certain antifungals such as fluconazole (Diflucan), itraconazole (Sporanox), and ketoconazole (Nizoral); cimetidine (Tagamet); clarithromycin (Biaxin, in Prevpac); fluoroquinolones including ciprofloxacin (Cipro, Proquin XR), gemifloxacin (Factive), levofloxacin (Levaquin), moxifloxacin (Avelox), norfloxacin (Noroxin), ofloxacin (Floxin), others; HIV protease inhibitors including indinavir (Crixivan), nelfinavir (Viracept), and ritonavir (Norvir, in Kaletra); medications for anxiety, pain or seizures; nefazodone; rifampin (Rifadin, in Rifamate, in Rifater, Rimactane); sedatives; other sleeping pills; ticlopidine (Ticlid); and tranquilizers. Your doctor may need to change the doses of your medications or monitor you carefully for side effects. Many other medications may also interact with ramelteon, so be sure to tell your doctor about all the medications you are taking, even those that do not appear on this list.
- tell your doctor if you have ever thought about killing yourself or planned or tried to do so, and if you have or have ever had chronic obstructive pulmonary disease (COPD, damage to the lungs that makes breathing difficult) or other lung disease, sleep apnea (condition in which you briefly stop breathing many times during the night) or other breathing problems, depression, mental illness, or liver disease.
- tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking ramelteon, call your doctor.

- do not drink alcohol during your treatment with ramelteon. Alcohol can make the side effects of ramelteon worse.
- you should know that some people who took ramelteon got out of bed and drove their cars, prepared and ate food, had sex, made phone calls, or were involved in other activities while partially asleep. After they woke up, these people were usually unable to remember what they had done. Call your doctor right away if you find out that you have been driving or doing anything else unusual while you were sleeping.
- you should know that your mental health may change in unexpected ways while you are taking this medication. It is hard to tell if these changes are caused by ramelteon or if they are caused by physical or mental illnesses that you already have or suddenly develop. Tell your doctor right away if you experience any of the following symptoms: agitation, anxiety, frenzied or abnormally excited mood, hallucinations (seeing things or hearing voices that do not exist), nightmares, memory problems, new or worsening depression, thinking about or trying to kill yourself, and any other changes in your usual thoughts, mood, or behavior. Be sure that your family knows which symptoms may be serious so that they can call the doctor if you are unable to seek treatment on your own.
