What is tafenoquine?
Tafenoquine is an anti-malaria medicine that works by interfering with the growth of parasites in the red blood cells of the human body.
Parasites that cause malaria typically enter the body through the bite of a mosquito. Malaria is common in areas such as Africa, South America, and Southern Asia.
Tafenoquine is used to treat malaria in people who are also using other anti-malaria medications.
Tafenoquine may also be used for purposes not listed in this medication guide.
You should not use tafenoquine if you have a genetic enzyme deficiency called glucose-6-phosphate dehydrogenase (G6PD) deficiency. Your doctor will perform a test to make sure you do not have this condition.
