G6PD and G6PD deficiency: Several studies have shown that primaquine (PMQ) is effective in killing P. falciparum gametocytes [10–12], with a single dose of PMQ (0.25 mg/kg), administered without testing for glucose-6-phosphate dehydrogenase (G6PD) deficiency, effectively clearing P. falciparum gametocytes while minimizing the severe complications associated with G6PD deficiency [13].
