Question
A patient of vivax malaria was treated with the standard dose of chloroquine. After 6 weeks he reported back with a relapse. Which drug will you use to treat the relapse episode: *1 pointA. ChloroquineB. PrimaquineC. Pyrimethamine + sulfadoxineD. Mefloquine
Solution
The correct drug to treat the relapse episode of vivax malaria is Primaquine (Option B). This is because Primaquine is effective against the dormant liver stage of the parasite (hypnozoites) which is responsible for relapses in vivax malaria. Chloroquine is typically used for the initial treatment, but if the patient relapses, it indicates that there are still dormant parasites in the liver, which Chloroquine cannot eliminate.
