Atovaquone/ Proguanil is a generic version of malarone. Reprapog belongs to a group of medicines called antimalarials. It contains two active ingredients Atovaquone & Proguanil Hydrochloride. Reprapog has two uses: to prevent malaria (for children & adults weighing between 11kg & 40kg) & to treat malaria (for children weighing between 5kg & 11kg). Malaria is spread by the bite of an infected mosquito, which passes the malaria parasite (Plasmodium Falciparum) into the bloodstream. Reprapog prevents malaria by killing this parasite. For people who are already infected with malaria, Reprapog also kills these parasites. As well as taking Reprapog, it is very important that you also take steps to avoid being bitten by mosquitoes: use insect repellent on exposed areas of the skin, wear light coloured clothing that covers most of the body, especially after sunset as this is the time when mosquitoes are most active, sleep in a screened room or under a mosquito net impregnated with insecticide, close windows & doors at sunset & consider using an insecticide (mats, spray, plug-ins) to clear a room of insects or to deter mosquitoes from entering the room.
