Quinamm

Generic name: Quinine (KWYE-nine)
Drug class: Antimalarial quinolines

Usage of Quinamm

Quinine is used to treat malaria caused by Plasmodium falciparum. Plasmodium falciparum is a parasite that gets into the red blood cells in the body and causes malaria. Quinine works by killing the parasite or preventing it from growing. This medicine may be used alone or given together with one or more medicines for malaria.

Quinine should not be used to treat or prevent night time leg cramps. This medicine may cause very serious unwanted effects and should only be used for patients with malaria.

This medicine is available only with your doctor's prescription.
