What is the most important information I should know about tafenoquine?

You should not use this medicine 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.

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.

What should I discuss with my healthcare provider before taking tafenoquine?

You should not use tafenoquine if:

  • you have a genetic enzyme deficiency called glucose-6-phosphate dehydrogenase (G6PD) deficiency; or
  • you are allergic to tafenoquine or similar medicines (such as primaquine).

Do not breast-feed while using tafenoquine, if your baby has G6PD deficiency (or has not been tested for it). If the baby does have G6PD deficiency, you should also not breast-feed for at least 3 months after your last dose of tafenoquine.

You may need to have a negative pregnancy test before starting this treatment.

Do not use tafenoquine if you are pregnant. It could harm the unborn baby. Use effective birth control to prevent pregnancy while you are using this medicine and for at least 3 months after your last dose.

Tell your doctor right away if you become pregnant.

  • a mental illness; or
  • liver or kidney disease.
