Common Uses of Dimenhydrinate

Dimenhydrinate is prescribed to treat several conditions, including:

• Sea and air sickness
• Meniere's disease
• Vestibular and labyrinth disorders (dizziness, nausea, vomiting)

Note: It does not treat symptoms caused by anticancer chemotherapy. The active substance, Dimenhydrinate, works by blocking histamine H1-receptors and m-cholinergic receptors in the central nervous system. It also calms hyperactive labyrinth function.

Benefits include reduced dizziness, antiemetic effects, mild sedation, and minor anti-allergic properties. Effects typically begin within 20-30 minutes and last 4-6 hours.

Dosage and Administration

Follow these guidelines for safe use:

• Motion sickness prevention: Take 30 minutes before travel
• Adults/teens (14+): 50-100 mg
• Children (2-6 years): 25-50 mg
• Children (7-14 years): 50 mg

For vestibular disorders, adults may take 50-100 mg every 4 hours (max 400 mg/day). Children require dose adjustment. Always take with a full glass of water and follow your doctor's instructions precisely.
