Ramelteon, marketed as Rozerem among others, is a sleep agent that selectively binds to the MT₁ and MT₂ receptors in the suprachiasmatic nucleus, instead of binding to GABAA receptors, such as with drugs like zolpidem. It appears to speed the onset of sleep and alter the total amount of sleep a person gets.


This medication is used to treat sleeplessness (insomnia). It helps you fall asleep faster so you can get a full night’s rest. Sleep is important for your ability to function, think clearly, and remain alert. Lack of sleep can cause problems such as depression, heart disease and accidents. Getting enough sleep allows your mind and body to repair itself and increases your energy throughout the day.

Ramelteon works like a natural substance called melatonin that is produced by your body. It helps regulate your sleep-wake cycle (circadian rhythm).

How to use Rozerem

  • Read the Medication Guide provided by your pharmacist before you start taking ramelteon and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
  • Take this medication by mouth with or without food, 30 minutes before bedtime, or as directed by your doctor. Do not take ramelteon with or immediately after a high-fat meal because fat can affect how well this drug works.
  • The manufacturer directs not to break the tablet before taking it. However, many similar drugs (immediate-release tablets) can be broken. Follow your doctor’s directions on how to take this medication.
  • Do not take a dose of this medication unless you have time for a full night’s sleep that lasts at least 7 to 8 hours.
  • Your dosage is based on your medical condition and response to therapy. Do not increase your dose or take it more frequently than prescribed.
  • Inform your doctor if you have any changes in mood (e.g., feelings of depression), if you continue to have trouble falling asleep, or if your insomnia worsens.
