Mefloquine: What It Is and When to Use It

If you’re traveling to a region where malaria is common, you’ve probably heard of mefloquine. It’s an antimalarial pill that helps stop the parasite before it makes you sick. Doctors usually prescribe it for short trips (like a few weeks) or for long stays in places where other malaria drugs don’t work well.

What makes mefloquine different is that you can take it once a week, instead of daily. That convenience is great, but the drug also has a reputation for causing some nervous system reactions. Knowing how to use it right can keep the good parts outweighing the bad.

How to Take Mefloquine Correctly

First, start the medication before you leave. Most guidelines say take the first dose at least two weeks before you get to the malaria‑risk area. That gives your body time to adjust and lets you spot any early side effects.

After the initial dose, keep taking a pill once a week while you’re in the endemic zone. When you leave, continue the weekly dose for four weeks. Skipping a dose can lower protection, so set a reminder on your phone or keep the pill bottle where you’ll see it daily.

Swallow the tablet with a full glass of water. Don’t crush, chew, or split it—those actions can change how the drug is absorbed and may increase side effects.

Alcohol can make the nervous side effects worse, so it’s safest to avoid drinking while you’re on mefloquine. Also, tell your doctor about any other medicines you’re taking, especially antidepressants, antiepileptics, or other antimalarials. Interactions can happen and may need dose adjustments.

Possible Side Effects & When to Call a Doctor

Most people experience mild symptoms like nausea, headache, or trouble sleeping. Those usually fade after a few days. If they stick around or get worse, note them down and contact a healthcare professional.

What many travelers worry about are the neuro‑psychiatric effects: vivid dreams, anxiety, or mood swings. If you notice extreme agitation, depression, or thoughts of harming yourself, seek medical help right away. Those reactions are rare, but they’re serious enough to stop the drug.

Skin rash, joint pain, or dizziness can also show up. Again, if they’re severe or don’t improve, get checked out. Some people develop a seizure‑type reaction, which is an emergency.

Before you start, ask your doctor if you have a history of psychiatric illness or epilepsy. Those conditions can raise the risk of serious side effects, and an alternative antimalarial might be safer.

Bottom line: mefloquine can be a solid choice for malaria protection when you follow the schedule, stay aware of how you feel, and keep an open line with your doctor or pharmacist. With the right precautions, you’ll spend less time worrying and more time enjoying your trip.
