Cinnarizine: What It Is and How It Helps
If you’ve ever felt dizzy on a boat or got sick while traveling, you might have heard of cinnarizine. It’s an antihistamine that doctors use to calm the inner ear and reduce motion‑related nausea. People also take it for vertigo, Ménière’s disease, and other balance problems.
Unlike some allergy pills, cinnarizine works by blocking calcium channels in the brain, which helps steady the signals that tell you when you’re moving. The result is less spinning, fewer headaches, and a calmer stomach.
How to Take Cinnarizine
Most adults start with 25 mg once or twice a day, usually after a meal. Your doctor may adjust the dose depending on how severe your symptoms are. It’s best to take it at the same times every day so your body gets used to the rhythm.
If you’re using it for travel‑related nausea, start the tablet an hour before you begin the journey. That gives the medication time to kick in and keep the queasy feeling away.
Don’t crush or chew the tablets – swallow them whole. If you miss a dose, take it as soon as you remember unless it’s almost time for your next one. In that case just skip the missed pill; don’t double up.
Possible Side Effects
Cinnarizine is generally safe when taken as directed, but some people notice drowsiness, dry mouth, or mild stomach upset. A small number of users report weight gain after several weeks of use – keep an eye on your diet if that happens.
Rarely, the drug can cause low blood pressure or movement‑related tremors. If you feel unusually sleepy while driving or operating machinery, stop what you’re doing and talk to a doctor.
Allergic reactions are uncommon but possible. Look out for rash, itching, swelling of the face or throat, and seek medical help right away if those appear.
Who Should Avoid It
If you have severe liver disease, heart problems, or a history of depression, tell your doctor before starting cinnarizine. The medication can interact with other drugs that affect the brain or heart, such as certain antidepressants and antihypertensives.
Pregnant or breastfeeding women should only use it if a health professional says the benefit outweighs any risk. It’s also not recommended for children under 12 unless a pediatrician specifically prescribes it.
Tips for Getting the Most Out of Cinnarizine
- Take the pill with food to reduce stomach upset.
- Avoid alcohol while on the medication; it can increase drowsiness.
- Stay hydrated, especially if you’re traveling long distances.
- Keep a short diary of when you feel dizzy or nauseous and how the drug helps. It makes follow‑up appointments easier.
Remember, cinnarizine works best when combined with practical steps like looking at the horizon on a boat, getting fresh air, and staying rested.
If your symptoms don’t improve after two weeks or get worse, schedule another check‑up. Adjusting the dose or trying an alternative treatment might be needed.
