Why malaria pills matter
Malaria is a life-threatening parasitic disease transmitted by Anopheles mosquitoes, present across sub-Saharan Africa, South and Southeast Asia, and parts of the Americas. Unlike most vaccine-preventable travel illnesses, there is no malaria vaccine approved for Canadian travellers. Prevention relies entirely on prescription antimalarial medication plus mosquito-bite avoidance.
Getting the right medication matters — both for effectiveness and tolerability. Here's how the three main options compare.
Malaria medication comparison
| Medication | Start before travel | Continue after | Approx cost | Best for |
|---|---|---|---|---|
| Malarone (atovaquone-proguanil) | 1–2 days | 7 days | $2–$8/tablet | Short trips, sensitive travellers |
| Doxycycline | 1–2 days | 4 weeks | $0.50–$1/tablet | Budget, longer trips |
| Mefloquine | 2–3 weeks | 4 weeks | $5–$10/tablet (weekly) | Long trips, weekly dosing |
Malarone (atovaquone-proguanil) — first-line for most travellers
Malarone is the most commonly prescribed antimalarial for Canadian travellers. It is well-tolerated, requires only 7 days post-trip (vs 4 weeks for alternatives), and has a convenient daily dosing schedule. Generic atovaquone-proguanil is medically identical to Malarone brand but significantly less expensive.
Cost: Brand Malarone $5–$8/tablet | Generic $2–$4/tablet
Not ideal for: Very long trips (4+ months) where doxycycline is more cost-effective
Doxycycline — budget-friendly for longer trips
Doxycycline is the most affordable antimalarial option, making it well-suited for extended travel (months vs weeks). It requires sun protection (increases photosensitivity) and should be taken with food to minimize GI upset. Women may be more prone to yeast infections during extended use.
Cost: $0.50–$1/tablet | $15–$30/month typical
Not suitable for: Children under 8, pregnancy or breastfeeding
Mefloquine — for long trips where weekly dosing is preferred
Mefloquine is taken once weekly and has the convenience of fewer doses on a long trip. However, it must be started 2–3 weeks before travel (to establish protective levels and identify any side effects early) and has a neuropsychiatric side-effect profile that makes it inappropriate for travellers with a history of depression, anxiety, or psychiatric conditions.
Not suitable for: Anyone with history of depression, anxiety, seizures, or psychiatric disorders
