Preventing Malaria Using Daily Medications

When traveling to malaria-endemic regions like Sub-Saharan Africa or South Asia, taking daily medications like atovacone proguanil, doxycycline, or primaquine can prevent Plasmodium falciparum infections. Atovacone proguanil inhibits liver stage development and is well-tolerated but not suitable for pregnant individuals. Doxycycline prevents malaria post-liver stage and is ideal for those at risk of tick-borne infections. Primaquine prevents hypnozoites in vivax malaria but requires G6PD testing; adherence is crucial for efficacy.
