Daraprim is an antiparasite medicine that helps prevent parasites from growing and reproducing in the body.
Daraprim is used in adults and children to treat or prevent certain types of malaria. However, this medicine is generally not preferred as a medicine to prevent malaria while traveling. When used to treat malaria, this medicine should be used together with a faster-acting anti-malaria medicine such as chloroquine or quinine.
Daraprim is also used to treat toxoplasmosis, an infection caused by the Toxoplasma parasite.
Daraprim may also be used for purposes not listed in this medication guide.
Follow all directions on your prescription label. Your doctor may occasionally change your dose. Do not take this medicine in larger or smaller amounts or for longer than recommended.

The Daraprim dose for treating toxoplasmosis is much higher than the dose for malaria.
Follow your doctor's dosing instructions very carefully.
Your dose may need to be cut in half after you have been taking Daraprim for 1 to 3 weeks (after 2 to 4 days for a child).
