Final answer:
The treatment for toxoplasmosis involves antiparasitic drugs, specifically a combination of pyrimethamine, sulfadiazine, and folinic acid, with spiramycin used for pregnant women in their first trimester.
Step-by-step explanation:
The medical treatment for toxoplasmosis is with antiparasitic drugs. Specifically, a combination of pyrimethamine, sulfadiazine, and folinic acid is recommended for six weeks to treat neurotoxoplasmosis caused by Toxoplasma gondii infections. Long-term maintenance doses may be necessary to prevent recurrence. For pregnant women in their first trimester, spiramycin is used instead to reduce the risk of transmission because it does not cross the placenta.
