What should a health care provider prescribe for malaria?

Any drugs taken for malaria chemoprophylaxis should be used in conjunction with personal protective measures to prevent mosquito bites (see Chapter 3).
How does primaquine help with malaria?
Primaquine is used in three major ways to prevent malaria: 1) as a primary chemoprophylactic agent: 2) for prevention of relapse due to liver stages of P. vivax or P. ovale infection (primaquine anti-relapse therapy [PART]): 3) in the treatment regimen of confirmed bloodstream infections with P.vivax or P.ovale infection as radical cure to prevent relapse. See adverse effects section for information on the need to test for glucose-6-phosphate dehydrogenase (G6PD) levels prior to use of primaquine.

Is atovaquone a prophylactic drug?
Atovaquone-proguanil is a fixed drug combination of atovaquone and proguanil in a single tablet. The two components are synergistic, inhibiting electron transport and collapsing mitochondrial membrane potential. Atovaquone-proguanil is effective as a causal ( acting at the liver stage) as well as a suppressive (acting at the blood stage) prophylactic agent. Atovaquone-proguanil must be taken daily, and it is essential that it be taken with a fatty meal - due to poor oral absorption otherwise, with associated diminished efficacy. Because of its causal effects, atovaquone-proguanil can be discontinued one week after departure from a malaria-endemic area. The elimination half-life of atovaquone-proguanil is 2 to 3 days in healthy adults, but only 1 to 2 days in children aged 6 to 12 years#N#Footnote#N#29. There are limited off-label data available that show that shorter prophylaxis courses with atovaquone-proguanil may be effective#N#Footnote#N#30#N#Footnote#N#31.
