What is Coartem?

Coartem contains a combination of artemether and lumefantrine. Artemether and lumefantrine are anti-malaria medicines that interfere with the growth of parasites in the red blood cells of the human body. Malaria is caused by parasites that enter the body through the bite of a mosquito. Malaria is common in areas such as Africa, South America, and Southern Asia.

Coartem is used only to treat malaria. Do not use this medicine to prevent malaria.
