Indications & Clinical Uses

Daraprim 25mg is an antiprotozoal medication used to treat infections caused by parasites that disrupt folate metabolism. It is primarily indicated for the following conditions:

  • Toxoplasmosis: Treats toxoplasmosis, including ocular and congenital infections, and in immunocompromised individuals.
  • Malaria: Used in combination with other antimalarial drugs to treat malaria.
  • Pneumocystis jirovecii pneumonia: Sometimes used in combination therapy for this condition in immunocompromised patients.

How It Works

  • Pyrimethamine works by inhibiting the enzyme dihydrofolate reductase, which is crucial for the synthesis of folate in parasites. By disrupting the folate metabolism, it prevents the parasites from replicating and spreading, thereby treating the infection. This mechanism is specific to the parasites and has a higher affinity for the protozoal enzyme compared to the human enzyme, reducing the impact on the host.

Side Effects

Daraprim 25mg can cause various side effects, ranging from common to serious. Common Side Effects:

  • Nausea and vomiting
  • Diarrhea
  • Anorexia
  • Rash
  • Fever
  • Headache

Serious or Rare Side Effects

  • Bone marrow suppression, leading to anemia, leukopenia, or thrombocytopenia
  • Allergic reactions, including skin rash and angioedema
  • Hepatic toxicity
  • Neurological effects, such as seizures and ataxia
  • Folic acid deficiency, which can be managed with folinic acid supplementation

Precautions & Warnings

Daraprim 25mg should be used with caution and under medical supervision. Important precautions include:

  • Pregnancy: Contraindicated during the first trimester due to potential teratogenic effects.
  • Breastfeeding: Not recommended as pyrimethamine is excreted in breast milk.
  • Bone marrow suppression: Regular blood tests are required to monitor for hematological changes.
  • Folic acid deficiency: Supplementation with folinic acid is necessary to prevent folate deficiency.
  • Epilepsy: Use with caution in patients with a history of seizures.

  • Trimethoprim: Increased risk of hematological toxicity.
