Quinine sulfate (quinine sulfate) — Uses, Dosage, Side Effects & Safety

Drug class: Antimalarial; Antiprotozoal

Overview

Quinine sulfate is a prescription medication used primarily to treat uncomplicated malaria caused by Plasmodium falciparum, a parasite transmitted by mosquitoes. It is not typically used for the prevention of malaria or for treating severe (complicated) malaria. Quinine works by interfering with the parasite's ability to digest and multiply within red blood cells, ultimately killing the parasite and helping to resolve the infection. It is often used in combination with other antimalarial drugs to improve effectiveness and reduce the risk of resistance. Key points for patients: Quinine sulfate should only be used under medical supervision. It is important to complete the full course of treatment, even if symptoms improve. This medication can cause side effects, some of which may be serious. Notify your healthcare provider if you experience any unusual symptoms.
