Meclizine 25 mg dosage for adults?

Meclizine 25 mg can be used for different indications, and the dose varies by condition.

- Motion sickness (OTC): 25–50 mg by mouth about 1 hour before travel. You may take another dose the next day if needed, but do not exceed 50 mg in 24 hours.

- Vertigo or dizziness (often Rx): typically 25–100 mg per day in divided doses. Common starting regimens are 25–50 mg every 6–8 hours, up to a total of 100 mg per day. Your clinician may adjust this based on your symptoms and tolerance.

Important notes:
- Drowsiness is common; avoid driving or operating heavy machinery until you know how it affects you.
- Avoid alcohol and other sedatives while taking meclizine.
- If you are pregnant, nursing, have glaucoma, an enlarged prostate, ulcers, or if you’re elderly, talk to a healthcare provider before use.
- If symptoms persist beyond a few days, worsen, or you’re considering a higher dose, consult a clinician.

If you’d like, tell me your indication (traveling, vertigo, etc.), and I can tailor the guidance more specifically. This information is general and not a substitute for medical advice.
