Acute
The medications prescribed for acute toxoplasmosis are the following:

Pyrimethamine – an antimalarial medication
Sulfadiazine – an antibiotic used in combination with pyrimethamine to treat toxoplasmosis
Combination therapy is usually given with folic acid supplements to reduce incidence of thrombocytopaenia. Combination therapy is most useful in the setting of HIV. Clindamycin
Spiramycin – an antibiotic used most often for pregnant women to prevent the infection of their children. (other antibiotics, such as minocycline, have seen some use as a salvage therapy). If infected during pregnancy, spiramycin is recommended in the first and early second trimesters while pyrimethamine/sulfadiazine and leucovorin is recommended in the late second and third trimesters. Latent
In people with latent toxoplasmosis, the cysts are immune to these treatments, as the antibiotics do not reach the bradyzoites in sufficient concentration. The medications prescribed for latent toxoplasmosis are:

Atovaquone – an antibiotic that has been used to kill Toxoplasma cysts inside AIDS patients
Clindamycin – an antibiotic that, in combination with atovaquone, seemed to optimally kill cysts in mice

Congenital
When a pregnant woman is diagnosed with acute toxoplasmosis, amniocentesis can be used to determine whether the fetus has been infected or not. When a pregnant woman develops acute toxoplasmosis, the tachyzoites have approximately a 30% chance of entering the placental tissue, and from there entering and infecting the fetus. As gestational age at the time of infection increases, the chance of fetal infection also increases.If the parasite has not yet reached the fetus, spiramycin can help to prevent placental transmission.
Toxoplasmosis is a parasitic disease caused by Toxoplasma gondii, an apicomplexan. Infections with toxoplasmosis are associated with a variety of neuropsychiatric and behavioral conditions. Occasionally, people may have a few weeks or months of mild, flu-like illness such as muscle aches and tender lymph nodes. In a small number of people, eye problems may develop. In those with a weak immune system, severe symptoms such as seizures and poor coordination may occur. If a person becomes infected during pregnancy, a condition known as congenital toxoplasmosis may affect the child.Toxoplasmosis is usually spread by eating poorly cooked food that contains cysts, exposure to infected cat feces, and from an infected woman to their baby during pregnancy. Rarely, the disease may be spread by blood transfusion. It is not otherwise spread between people. The parasite is known to reproduce sexually only in the cat family. However, it can infect most types of warm-blooded animals, including humans. Diagnosis is typically by testing blood for antibodies or by testing the amniotic fluid in pregnant people for the parasites DNA.Prevention is by properly preparing and cooking food. Pregnant people are also recommended not to clean cat litter boxes or, if they must, to wear gloves and wash their hands afterwards. Treatment of otherwise healthy people is usually not needed. During pregnancy, spiramycin or pyrimethamine/sulfadiazine and folinic acid may be used for treatment.Up to half of the worlds population is infected by toxoplasmosis, but have no symptoms.
