Frequently Asked Questions

  1. What is Daraprim, and what does it treat?

    Daraprim, known by its generic name pyrimethamine, is an antiparasitic medication. It’s primarily used to treat toxoplasmosis, a serious infection caused by the Toxoplasma parasite. This condition can occur in the body, brain, or eyes and is particularly dangerous for people with HIV infection. Daraprim is also used to treat and prevent certain types of malaria, although it’s usually not the first choice for malaria prevention in travelers.

  2. How should Daraprim be taken?

    Daraprim should be taken by mouth, following your doctor’s instructions closely. It’s recommended to take this medication with food to decrease the likelihood of nausea and vomiting. Dosage is determined based on the infection being treated, the patient’s medical condition, age, and response to treatment. It’s crucial to maintain a constant level of the drug in your body for it to be most effective, so regular intake as prescribed by your doctor is important.

  3. What are the common side effects of Daraprim?

    While Daraprim can be an effective treatment, it does come with potential side effects. Common issues include vomiting, loss of appetite, and in some cases, allergic reactions like hives, difficulty breathing, and swelling of the face, lips, tongue, or throat. More serious side effects can include signs of blood problems (easy bruising or bleeding, high fever, severe tiredness), sore throat, and severe skin reactions. If you face any side effects, consult your doctor right away.

  4. Can Daraprim be used during pregnancy?

    Daraprim should be used during pregnancy only if clearly needed and directed by a doctor due to potential risks to the unborn baby. In some cases, it’s given to pregnant women to treat toxoplasmosis after evaluating the risks and benefits.

  5. Is it safe to breastfeed while taking Daraprim?

    Daraprim can pass into breast milk and may cause side effects in a nursing infant. Discuss with your doctor whether you should either discontinue the drug or stop breastfeeding.

  6. What if I miss a dose or overdose?

    If you miss a dose, take it as soon as you remember unless it’s almost time for your next dose. In the case of an overdose, seek emergency medical attention. Symptoms of overdose might include stomach pain, vomiting, or convulsions.

  7. What should be avoided while taking Daraprim?

    Patients should follow their doctor’s advice regarding any restrictions on food, beverages, or activity while taking Daraprim. It’s also crucial to avoid skipping doses or stopping the medication without your doctor’s approval, as this could increase parasite resistance and make the infection more difficult to treat.

  8. How does Daraprim work?

    Daraprim works by preventing parasites from producing necessary proteins, thus stopping their growth and reproduction within the body. It targets the parasites while sparing human cells, making it an effective treatment against infections like toxoplasmosis and malaria.
