Daraprim is a medication used to treat parasitic infections, specifically toxoplasmosis. Pyrimethamine is typically administered in combination with an antibiotic called sulfadiazine. Daraprim contains pyrimethamine, which belongs to a class of drugs known as antiparasitics. It works by killing parasites. Daraprim is available in tablet form and is taken orally.

Daraprim is a medication typically used in adults and children to treat or prevent certain types of malaria. However, it is not the preferred medication for preventing malaria while traveling. When used to treat malaria, Daraprim should be used alongside a faster-acting anti-malaria drug, such as chloroquine or quinine.

Uses and Dosage

Daraprim tablet is typically taken orally once or twice daily, or as directed by your doctor. Take the medication with food to decrease nausea and vomiting. If severe vomiting occurs, your doctor may adjust your dose or direct you to stop taking the medication. Do not take more or less of this drug than prescribed. Do not stop taking it before completing this prescription unless directed to do so by your doctor, even if you feel better. Skipping or changing your dose without approval from your doctor may cause the number of parasites to increase, make the infection more difficult to treat (resistant), or worsen side effects.

The recommended dosage of Daraprim depends on the specific condition being treated, as well as the patient's age, weight, and medical history.

  • For toxoplasmosis, the recommended dosage of Daraprim is typically 50-75 mg per day, taken orally in divided doses for several weeks.
  • For malaria, the dosage may vary based on the severity of the infection and the patient's weight but is typically given in combination with other medications such as artesunate.
