Answer

Answer

For dapsone, the dosage is 100 mg daily by mouth if it is administered alone. If dapsone is given with pyrimethamine (plus leucovorin), the dosage is 50 mg of dapsone daily by mouth with 50 mg of pyrimethamine weekly and 25 mg of leucovorin weekly. Dapsone with pyrimethamine (plus leucovorin) provides protection against T gondii infection, but not other bacterial infections.
