Primaquine (Primaquine)


What is primaquine?

Primaquine is a medication to treat or prevent malaria, a disease caused by parasites. primaquine works by interfering with the growth of parasites in the 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.

Vivax malaria is a form of malaria in which parasites travel from the bloodstream into other cells and tissues of the body. This can cause a second infection (relapse) to occur.

Primaquine is used to prevent malaria from coming back in people who have been infected with the vivax form of this disease.

Primaquine may also be used for purposes not listed in this medication guide.

  • you have an autoimmune disorder, such as lupus or rheumatoid arthritis; or

  • you are pregnant or may become pregnant; or

  • you have recently used another malaria medicine called quinacrine or Atabrine.

To make sure primaquine is safe for you, tell your doctor if you have:

  • a genetic enzyme deficiency called glucose-6-phosphate dehydrogenase (G6PD) deficiency;

  • heart disease, heart rhythm disorder (including slow heartbeats);

If you are a woman, keep using birth control after you stop taking primaquine, until you have at least one menstrual period. If you are a man, keep using condoms for at least 3 months after your last dose. Tell your doctor right away if a pregnancy occurs while either the mother or the father is using primaquine.

In addition to taking primaquine, use protective clothing, insect repellents, and mosquito netting around your bed to further prevent mosquito bites that could cause malaria.
