If you’re planning a trip to a malaria‑risk area or have been prescribed mefloquine, you probably have a lot of questions. This guide breaks down the basics: what the drug does, how to take it, what to watch out for, and when to call a doctor. No jargon, just clear answers you can use right away.
Mefloquine is an antimalarial pill that both prevents infection and treats mild cases. It works by stopping the malaria parasite from multiplying in your blood. Because it stays in your system for a long time, you only need to take it once a week for prevention, which is handy for longer trips.
Start the medication at least one week before you enter a malaria‑endemic zone. Take the first dose with a full glass of water, preferably with food to reduce stomach upset. After the initial dose, keep the weekly schedule – same day, same time – until you’ve left the risk area and completed an extra week of treatment.
For treatment, doctors usually give a higher loading dose followed by smaller daily doses for three days. Always follow the exact schedule your prescriber gives you; skipping or doubling a dose can reduce effectiveness and raise side‑effect risk.
Most people tolerate mefloquine well, but some common side effects include nausea, headache, dizziness, and mild insomnia. If these symptoms linger more than a few days or get worse, let your doctor know.
Serious side effects are rarer but need immediate attention: severe anxiety, vivid hallucinations, depression, or sudden changes in mood. Heart palpitations, ringing in the ears, or an upset stomach that won’t go away could also signal a problem. Seek medical help right away if any of these appear.
People with a history of mental health issues, epilepsy, or heart rhythm problems should discuss alternatives before starting mefloquine. The drug can interact with several other medications, especially other antimalarials, certain antidepressants, and some heart medicines. Bring your full medication list to the appointment so your doctor can check for conflicts.
If you’re pregnant or breastfeeding, mefloquine is usually not recommended unless the benefits outweigh the risks. Again, talk to a healthcare professional to weigh the options.
When buying mefloquine online, stick to reputable pharmacies that require a prescription and display their licensing information. Look for reviews that mention reliable shipping and authentic packaging. Avoid sites that offer the drug without a prescription or at prices that seem too good to be true – they could be counterfeit and unsafe.
Bottom line: mefloquine can be a solid choice for malaria prevention when taken correctly and monitored for side effects. Keep a schedule, stay aware of how you feel, and keep the lines of communication open with your doctor. Safe travels!
