E-mail: Kristina.langholz@gmail.comAbstractThe ability of Plasmodium vivax to relapse is a challenge to its management. Primaquine is the only drug licensed for the eradication of hypnozoites. We report the case of a non-immune traveller, who required high dosage primaquine treatment to obtain radical cure of vivax malaria, emphasizing the importance of country-specific and weight-based dosing of primaquine.
