خلاصه
Pyrimethamine inhibits parasitic dihydrofolate reductase, and supplemental folic acid can reduce its antiparasitic effect. For toxoplasmosis this may lead to treatment failure. Folinic acid is usually used instead to protect the marrow without blunting efficacy.
معنای این تداخل به زبان ساده
Folic acid and Pyrimethamine can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
