About
What is Toxoplasmosis?
Toxoplasmosis is a serious, sometimes fatal infection caused by the Toxoplasma gondii (T. gondii) parasite, one of the most common parasites in the world. While many people in the U.S. may carry the parasite, only a small number will develop active infection.¹
The parasite can cause:
- A serious brain disease that can possibly lead to death in people with weakened immune systems, such as those living with HIV/AIDS
- Infections in the eye that can lead to blindness
- Miscarriage or stillbirth in women that are pregnant
- Developmental abnormalities and/or birth defects in babies as a result of exposure to the parasite before they are born
Taking DARAPRIM
DARAPRIM and a sulfonamide work together to block folic acid synthesis in the parasite, which interferes with parasite reproduction in your body.
DARAPRIM may cause folate deficiency which can lead to blood toxicity. Leucovorin (Folinic Acid) may be prescribed to help counter this effect.
At the first appearance of a skin rash you should stop use of DARAPRIM and seek medical attention immediately. Other symptoms that may be early indications of serious disorders include sore throat, paleness, and purple spots on skin or swollen tongue. DARAPRIM should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. The most common side effects that may occur with DARAPRIM include allergic reactions, blood disorders (including neutropenia or a low level of neutrophils, a white blood cell important to fight off infections), tongue changes, blood in the urine, heart rhythm disorders, anorexia and vomiting.

Taking DARAPRIM may result in allergic reactions that can be severe (such as Stevens-Johnson syndrome, toxic epidermal necrolysis, erythema multiforme, and anaphylaxis). Symptoms of an allergic reaction or the severe reactions may include: fever, body aches, facial or tongue swelling, skin pain, peeling of skin, blisters on your skin and mucous membranes, itching, rash, red itchy welts, wheezing, asthma symptoms, or dizziness or feeling faint. At the first appearance of a skin rash or any of the above symptoms, stop the medication and immediately seek medical attention. Other signs and symptoms of serious disorders may include sore throat, paleness, tongue changes, and purple skin color.
Make sure to tell your healthcare provider if you have any heart conditions, especially if you experience irregular heartbeat.
