Daridorexant
Summary
Daridorexant is mainly used for the treatment of insomnia in adults. It helps those who have difficulty falling asleep or staying asleep.
Daridorexant works by blocking the action of orexin, a substance in the brain that promotes wakefulness. It reduces wakefulness and promotes sleep, making it easier for you to fall and stay asleep.
The usual daily dose for adults is 25 mg to 50 mg, taken orally once per night, within 30 minutes of going to bed.
Common side effects of Daridorexant include headache, fatigue, and nausea. Serious adverse effects can include sleep paralysis, hallucinations, and complex sleep behaviors.
Daridorexant can cause next-day drowsiness, complex sleep behaviors, and worsening of depression or suicidal thoughts. It should not be used by patients with narcolepsy or a history of hypersensitivity to the drug. Alcohol and other CNS depressants should be avoided while taking this medication.
