Primaquine clears the liver stage of vivax malaria to prevent relapse (check G6PD first). It belongs to the Antimalarial (treatment) group. These treat malaria; the choice depends on the malaria type and region.
Confusion, fits or very high fever (severe malaria — emergency)
Dark urine (possible blood breakdown, esp. G6PD)
Severe rash or allergy
Not a prescription — no dose shown. The right dose of primaquine depends on age, weight, kidney/liver function and the condition, so MedDroid does not show a dose here. Always get your dose from a doctor or pharmacist and the leaflet inside the pack. General educational information only.
Frequently asked questions
Why is primaquine given after other malaria drugs?
In some malaria types (vivax/ovale), the parasite hides in the liver. Primaquine clears these to prevent relapse — but G6PD status must be checked first.
Is malaria treatment different for severe cases?
Yes — severe malaria is treated urgently in hospital, usually with injectable artesunate, then a full oral course.
