What should you know about malaria prophylaxis?

Malaria prophylaxis combines prescribed preventive medicine with bite protection chosen for your destination and health needs. It reduces risk but does not replace care if fever or other symptoms develop during or after travel.

The right plan depends on the countries and regions visited, season, length and style of travel, local parasite resistance, and your medical history. Options may include a prescribed antimalarial tablet schedule, insect repellent, long clothing, screened rooms, and bed nets. Different medicines have different precautions, interactions, and timing around travel, so a medicine used by another traveller may not suit you.

Book a travel health consultation early enough to review your itinerary, allergies, pregnancy or pregnancy plans, kidney or liver conditions, mental health history, and regular medicines. Follow the selected schedule precisely and ask what to do after a missed dose or vomiting. Use repellent and physical barriers consistently, especially from dusk through dawn when some malaria-carrying mosquitoes are active. Keep seeking medical advice if you become unwell after returning.

Seek urgent medical assessment for fever, chills, headache, marked weakness, confusion, breathing trouble, or repeated vomiting during travel or after returning from a malaria area. Tell the clinician where you went and which preventive medicine you took. Do not self-treat a new fever with leftover tablets.

Ask which destinations on your route carry malaria risk, when to start and stop the medicine, whether your regular medicines interact with it, and which side effects need prompt help.
