Quinine is a medication used to treat malaria and babesiosis. This includes the treatment of malaria due to
Plasmodium falciparum that is resistant to chloroquine when artesunate is not available. While sometimes
used for restless legs syndrome, quinine is not recommended for this purpose due to the risk of serious side effects.
It can be taken by mouth or intravenously. Malaria resistance to quinine occurs in certain areas of the world.
Quinine is also the ingredient in tonic water that gives it its bitter taste.
