Daraprim is an antiparasite medicine that helps prevent parasites from growing and reproducing in the body.

Daraprim is used in adults and children to treat or prevent certain types of malaria. However, this medicine is generally not preferred as a medicine to prevent malaria while traveling. When used to treat malaria, this medicine should be used together with a faster-acting anti-malaria medicine such as chloroquine or quinine.
