Medical Information

I. Managing Headache

Headache is one of the more common side effects of daridorexant, usually mild to moderate, and often appears early in treatment.

Observe patterns: Record the timing and intensity of headaches; most are more noticeable in the first 1–2 weeks of treatment and then gradually diminish.

Ensure hydration: Dehydration can worsen headaches; drink an appropriate amount of water during the day, and avoid drinking large amounts before bed to prevent nocturia from interfering with sleep.

Avoid triggers: Reduce caffeine and alcohol intake, maintain a regular schedule, and avoid staying up late and prolonged eye strain.

Symptomatic treatment: For mild to moderate headaches, analgesics such as acetaminophen may be used as directed by a doctor; if the headache is severe, persistent, or accompanied by nausea and vomiting, seek medical attention promptly.

II. Managing Drowsiness

Drowsiness mainly manifests as next-morning grogginess and slowed reactions, and is closely related to insufficient time in bed.

Ensure adequate time in bed: Ensure at least 7 hours in bed after dosing; less than 7 hours significantly increases the risk of next-day drowsiness.

Fix the dosing time: Take the medication at the same time every night to help the body establish a rhythm and reduce residual effects.

Drive with caution: During the initial treatment period or dose adjustment period, avoid driving, operating machinery, or working at heights; resume only after confirming there is no residual drowsiness.

Avoid additive factors: Do not drink alcohol during treatment, and do not use it with other sedative medications to avoid worsening drowsiness.

III. Managing Fatigue

Fatigue is often related to sleep quality, residual drug effects, and daily rhythm.

Assess sleep quality: If fatigue persists, check for insufficient sleep, fragmented sleep, or comorbid other sleep disorders.

Moderate activity: Regular aerobic exercise during the day (such as walking or jogging) can help improve daytime energy, but avoid vigorous exercise within 3 hours before bed.

Adjust diet: Avoid high-sugar, high-fat diets that cause daytime drowsiness, and avoid overeating at lunch.

Record and follow up: If fatigue persists for more than 2–4 weeks or significantly affects daily life, follow up to assess whether the dose needs adjustment.

IV. General Principles

Most side effects diminish with continued treatment; observe patiently in the early stage and do not rush to stop the medication.

Do not increase or decrease the dose on your own; any adjustment requires a doctor's guidance.

If abnormal sleep-walking, severe drowsiness, or mood changes occur, stop the medication immediately and seek medical attention.
