Ramelteon is a medication primarily used to treat insomnia, particularly for those who have difficulty falling asleep. It works by mimicking the action of melatonin, a hormone that regulates the sleep-wake cycle. By binding to specific receptors in the brain, ramelteon helps promote sleep onset without the risk of dependence associated with some other sleep medications. Unlike traditional sleep aids, ramelteon is not classified as a controlled substance, making it a safer option for long-term use. It is typically taken shortly before bedtime and is available in tablet form. Common side effects may include dizziness, fatigue, and headache.
