Flunarizine: What You Need to Know

If you’ve landed here, chances are you or someone you care about is looking at flunarizine as a migraine option. It’s a calcium‑channel blocker that many doctors prescribe to prevent headaches, but the name can sound intimidating. Let’s break it down into bite‑size pieces so you can decide if it’s right for you.

How Flunarizine Works and Who It Helps

Flunarizine blocks calcium from entering certain brain cells. By doing that, it calms the nerves that can over‑react and spark a migraine. It’s not a rescue pill you take when a headache starts; instead, you take it every day to lower the chance of a migraine hitting.

The drug is most popular in Europe and parts of Asia. In the U.S. it’s less common, but doctors sometimes prescribe it off‑label. It’s also used for vertigo and some movement disorders, though migraine prevention is its main claim to fame.

Dosage, How to Take It, and What to Expect

Typical adult dosing starts at 5 mg once daily, taken with food to avoid stomach upset. Some people need a higher dose (up to 10 mg) if migraines are stubborn, but your doctor will decide based on response and tolerance.

Take the pill at the same time each day—consistency helps keep blood levels steady. If you miss a dose, take it as soon as you remember unless it’s almost time for the next one; then just skip the missed dose. Don’t double up.

Most people notice fewer migraine days after 4–6 weeks. That lag can be frustrating, but it’s normal; the medication needs time to modulate the brain’s calcium channels.

Common Side Effects and Safety Tips

Like any drug, flunarizine has side effects. The most frequent are:

Weight gain – keep an eye on your diet and stay active.
Drowsiness or fatigue – take it with breakfast if you feel sleepy.
Depression or mood changes – tell your doctor right away if you feel down.
Dry mouth – sip water throughout the day.

Rarely, it can cause Parkinson‑like symptoms or severe depression. If you notice tremors, stiffness, or any sudden mood shift, contact a healthcare professional immediately.

Because flunarizine blocks calcium, people with low blood pressure or heart problems should discuss risks with their doctor. It’s also not recommended for pregnant or breastfeeding moms unless the benefits clearly outweigh the risks.

Practical Tips for Getting the Most Out of Flunarizine

Track your migraine frequency in a simple notebook or app. Seeing a clear pattern helps you and your doctor decide if the dose needs adjusting.

Combine the medication with lifestyle tweaks: regular sleep, hydration, and avoiding known triggers like certain foods or bright lights. Flunarizine works best when you give it a supportive environment.

Never buy flunarizine from an unverified online pharmacy. Look for a licensed pharmacy, check the seller’s credentials, and keep a record of the prescription.

Finally, keep follow‑up appointments. Your doctor will want to check blood pressure, weight, and mood after the first month, then periodically thereafter.

Flunarizine can be a game‑changer for chronic migraine sufferers when used correctly. Armed with the right info, you can use it safely and see fewer headache days. If you have more questions, talk to your healthcare provider—they’ll tailor the plan to fit your unique needs.
