Pyrimethamine is an antiparasite medicine that helps prevent parasites from growing and reproducing in the body.

Pyrimethamine is used together with other medicines to treat or prevent certain types of malaria. However, pyrimethamine is generally not preferred as a medicine to prevent malaria while traveling.

Pyrimethamine is also used to treat toxoplasmosis, an infection caused by the Toxoplasma parasite.
