Description
Circadin is a prescription medication containing 2 mg of prolonged-release melatonin, specifically developed to support the natural sleep-wake cycle. It is primarily prescribed for adults aged 55 and older who experience poor sleep quality due to insomnia or age-related changes in melatonin production. Unlike standard melatonin supplements, Circadin is designed to mimic the body’s natural nighttime release of melatonin, helping to promote longer and more restful sleep.
Melatonin is a hormone that the body naturally produces in response to darkness. Circadin supplements this hormone in a controlled-release form, helping people fall asleep faster, sleep more deeply, and reduce night-time awakenings. It offers a gentle alternative to traditional sleeping pills without causing dependency or significant daytime drowsiness.
Circadin is taken orally, one to two hours before bedtime, and is most effective when combined with good sleep hygiene practices, such as avoiding screens before bed and maintaining a regular sleep routine. It begins working within the first few days, with full benefits often seen after one to two weeks of consistent use.
It is generally well tolerated, though some individuals may experience mild side effects such as headache, nausea, or drowsiness. It should not be used together with alcohol or strong sedatives, as these may impair its effectiveness.
General Information
