Malaria Prophylaxis

Key takeaways

• The correct option depends on exact destination, season, rural exposure, resistance and access to medical care.
• Medicines start before exposure and continue afterwards for different periods, making itinerary and adherence important.
• Prophylaxis is not fully protective; any fever during or after travel needs urgent malaria testing.

The listings below are not suitable for every itinerary or traveller; pregnancy, age, kidney health and psychiatric history affect selection.

Choosing a medicine

Atovaquone–proguanil has a short post-travel course but kidney and cost considerations. Doxycycline also prevents some other infections but causes photosensitivity and is unsuitable in pregnancy and young children. Mefloquine is taken weekly but avoided with certain psychiatric or seizure histories.

Bite prevention and planning

Use effective repellent, long clothing, screened or air-conditioned rooms and an insecticide-treated net where needed. Start travel-health review early enough to test tolerance and arrange vaccines. Emergency standby treatment is not a routine substitute for prophylaxis or diagnosis.

When to seek urgent care

Seek urgent medical assessment for any fever during or after malaria-risk travel, especially with confusion, jaundice, breathing difficulty, fainting, repeated vomiting or severe weakness.
