Belsomra is FDA-approved for the treatment of insomnia characterized by difficulties with sleep onset and/or sleep maintenance in adults. It is typically prescribed when lifestyle changes and other non-pharmacological approaches have not been sufficient.
Belsomra belongs to a class of medications called orexin receptor antagonists. It works by blocking the activity of orexin, a neurotransmitter in the brain that helps regulate the sleep-wake cycle. By inhibiting orexin, the medication helps reduce wakefulness and facilitates the transition to sleep.
Belsomra should only be taken at night, within 30 minutes of going to bed, with at least 7 hours remaining before you need to be awake. Common side effects include drowsiness, headache, and dizziness. It may cause next-day impairment and should be used with caution when combined with alcohol or other CNS depressants. This medication has potential for dependence and is not recommended for use during pregnancy or while breastfeeding. Always follow your healthcare provider's dosing instructions carefully.
