Meclizine Dosage: Simple Answers for Motion Sickness and Vertigo
If you’ve ever felt queasy on a boat or dizzy after standing up too fast, chances are you’ve heard of meclizine. It’s an over‑the‑counter antihistamine that helps calm the inner ear and reduces nausea. But how much should you actually take? Below is a quick rundown that covers the most common scenarios.
Standard Adult Dose
For most adults, the typical meclizine tablet comes in 25 mg or 50 mg strengths. The usual recommendation is one 25‑mg tablet taken about an hour before travel or when symptoms start. If you need stronger relief, a single 50‑mg tablet works for many people.
Don’t exceed two tablets (100 mg) in a 24‑hour period unless your doctor says it’s okay. Taking more won’t make the effect faster and can increase side effects like drowsiness.
Kids and Teens
Children under 12 should not use meclizine without a doctor’s advice. For kids aged 12‑17, doctors often suggest half an adult tablet (about 12.5 mg) if the medication is needed. Always follow the pediatric dosing instructions on the label or given by your pharmacist.
Special Situations
If you’re pregnant, nursing, or have liver disease, talk to a healthcare professional before reaching for meclizine. Some doctors may lower the dose or suggest an alternative medication.
People who operate heavy machinery or drive should be cautious. Meclizine can cause drowsiness that lasts several hours, so plan your activities accordingly.
How to Take It Properly
Swallow the tablet whole with a glass of water. You don’t need food, but taking it with something light can help if you’re prone to stomach upset.
If you miss a dose and you’re still feeling nauseous, take one tablet as soon as you remember—unless it’s almost time for your next scheduled dose. In that case, skip the missed one; don’t double up.
When to Seek Help
If you notice severe dizziness, vision changes, or an allergic reaction (rash, itching, swelling), get medical help right away. These aren’t normal side effects.
Also, if the medication stops working after a few days, talk to your doctor. Sometimes the body builds tolerance and a different drug works better.
Quick Recap
- Adults: 25‑50 mg once before symptoms, max 100 mg per day.
- Teens (12+): about half an adult tablet if approved.
- Never give to kids under 12 without a doctor.
- Watch for drowsiness—avoid driving until you know how it affects you.
- Missed dose? Take it when you remember unless the next dose is close.
Meclizine works well for many people, but the right dosage makes all the difference. Keep these guidelines handy, read the label, and don’t hesitate to ask your pharmacist or doctor if anything feels unclear. Safe travels and steady balance!
