Sulfadoxine — Uses, Dosage, Side Effects & Safety
Drug class: Antimalarial, Sulfonamide Antibiotic
Overview
Sulfadoxine is an antimalarial and sulfonamide antibiotic most commonly used in combination with pyrimethamine to treat and prevent malaria, especially in regions where malaria is resistant to other medications. It works by stopping the growth of the malaria parasite in the blood, helping to clear the infection and prevent its spread. This medication is also sometimes used for the prevention of malaria in travelers or in mass drug administration campaigns in high-risk areas. It is important to take the full course of treatment, even if you start to feel better, to ensure the infection is completely cleared. Key points: Sulfadoxine is not effective against all types of malaria and should only be used under medical supervision. It is usually given with pyrimethamine and is not suitable for people with sulfa allergies.
