G6PD and malaria: Other studies on SLD-PQ to date have focused on the safety of the WHO-recommended dose of 0.25 mg/kg of SLD-PQ, which was demonstrated to be safe in Senegal, when given with artemether-lumefantrine, dihydroartemisinin-piperaquine, or artesunate-amodiaquine to 54 phenotypically G6PD-d patients with malaria [21]; in Tanzania, when given with artemether-lumefantrine to 33 phenotypically G6PD-d patients with malaria [22]; and at the Thai-Myanmar border, when given with dihydroartemisinin-piperaquine to 124 phenotypically G6PD-d individuals in a mass drug administration campaign [23].
