Ramelteon

Ramelteon

Properties

This medicine contains ramelteon as active ingredient. It is an psychoactive drug that has a specific effect on certain areas of the brain. This medicine is a unique hypnotic that activates the same nerve endings that are acted on by melatonin, the hormone that is essential to natural sleep and our normal circadian rhythms that dictate sleep-wake  patterns.

Prescribed for

This medicine is prescribed for sleeping disorders characterized by difficulty falling asleep.

Difficulty sleeping may be a sign of another physical or psychological problem. If this medicine does not help, ask your doctor to look for other issues that might be interfering with your sleep and have not yet been discovered.

Before using this medicine

Before you use this medicine check with your doctor, or  pharmacist:

•    if you ever had any unusual or allergic reaction to this medicine or any psychoactive drug;

•   if you are allergic to any medicines, foods or other substances;

•    if you are pregnant or intend to become pregnant while using this medicine (animal studies have shown toxic effects to developing fetuses);

•   if you are breast-feeding an infant;

•   if you have kidney or liver disease.

Treatment

The information below is based on the dosage guidelines your doctor uses. Depending on your condition and medical history, your doctor may prescribe a different regime. The recommended starting dose for adults is 8 mg taken 30 minutes before sleep. The medicine is not recommended for children.

Studies have shown that the medicine has no potential for abuse and is not considered a controlled substance under federal laws. Studies of up to 20 times the recommended dosage showed no indication of abuse potential with this medicine. The drug passes rapidly into the blood and starts working in a few minutes. It is broken down in the liver and mostly passes out of the body in the urine.

Seniors retain almost twice as much of this medicine as younger adults and should use the lowest effective dose.

Warnings and Cautions

•    Complex sleep-related behaviors including driving, eating, and walking while asleep, with no memory of the event afterward, can occur with this medicine and other sleep medications. These activities happen after taking a sedative-hypnotic product while you are not fully awake.

•    People with severe liver disease should not take this drug. Even those with mild liver disease can have as much as 4 times as much medicine in their blood as those with normal liver function.

•    The medicine does not cause difficulty breathing. However, people with chronic obstructive pulmonary disease and other respiratory conditions have not yet been studied with this drug.

•    In depressed patients taking any hypnotic drug, worsening depression, including suicidal thoughts, is possible.
