Malaria prophylaxis in travellers

A clinician considers the places you will visit, the route between them, travel season, trip length, accommodation, activities, age, pregnancy, allergies, medical conditions, and current medicines. Risk can differ between nearby regions, so a country name alone may not give enough detail. Some travellers need prescribed tablets; others may be advised that bite prevention is the main measure.

Prophylaxis does not treat an established malaria infection. It also does not make fever harmless. Mosquito protection includes long sleeves and trousers when practical, repellent on exposed skin, screened rooms, bed nets where appropriate, and limiting outdoor exposure when mosquitoes are active.

Book a travel-health consultation before departure and bring your itinerary, departure date, planned activities, allergies, health conditions, and medicine list. Follow the prescribed timing before, during, and after the trip; the schedule differs by medicine. Use reminders for doses and keep tablets accessible rather than in checked luggage.

If a dose is missed, vomited, or stopped because of a side effect, ask a clinician or pharmacist what to do. Do not double doses unless specifically instructed. Continue bite-avoidance measures throughout the journey and keep a record of the areas visited.

Seek urgent medical assessment for fever, chills, sweats, headache, profound tiredness, confusion, breathing difficulty, repeated vomiting, or yellowing of the skin after travel in a malaria area. Mention the travel dates and destinations and say that malaria exposure is possible, even if you used prophylaxis.

Ask which parts of the itinerary have malaria risk, when to start and stop the medicine, how to handle side effects or missed doses, and which symptoms require immediate help.
