What should you know about Lariam malaria prophylaxis?

Lariam is the brand name commonly used for mefloquine, a medicine taken to reduce the chance of malaria during exposure in areas where it is suitable. Choice depends on the destination, local resistance patterns, trip length, other medicines and your health history. It does not replace measures that prevent mosquito bites, and no tablet removes every possibility of infection. Malaria can become serious, so fever during or after travel needs medical attention even if prophylaxis was taken.

Book a travel-health consultation early enough to review the itinerary and start any recommended medicine as directed. Tell the clinician about anxiety, depression, psychosis, seizures, heart rhythm problems, pregnancy plans, allergies and all medicines or supplements. Take doses on the prescribed schedule and follow instructions about food and water. Use repellent, long clothing, screens or nets where practical, and check what to do if a dose is missed or vomiting occurs.

Stop and seek urgent medical advice for severe mood or behaviour changes, hallucinations, a seizure, fainting, chest palpitations, severe dizziness or an allergic reaction. During travel or after returning, urgent assessment is needed for fever, chills, headache, confusion, breathing difficulty or marked weakness. Do not self-treat a suspected malaria illness with leftover tablets.

Is mefloquine appropriate for my destination and medical history? When should I begin and stop it? What alternatives fit my itinerary? Which symptoms mean I should stop the medicine or seek emergency care?
