Therefore, standard dosages of MB appear to be safe in G6PD‐deficient African populations with predominantly class III G6PD deficiency. Introduction Malaria remains the most important parasitic disease and is globally responsible for 300–500 million fever episodes and 1.5–2.7 million deaths per year WHO 1997. Patients with severe G6PD deficiency should not take primaquine; unfortunately at this stage there are no alternative drug regimens available. G6PD deficiency is restricted to certain populations or segments of populations; therefore it may be that not every person requiring primaquine will be tested for their G6PD status, only those considered high risk for potential deficiency.

G6PD deficiency is a genetic condition that is caused by an alteration a mutation or a change in the G6PD gene. This mutation prevents the production of the normal enzyme. The mutation is passed on in families in an X-linked recessive pattern. If primaquoine phosphate is used, CDC recommends a dose of 30 mg base by mouth daily for 14 days. Because both tafenoquine and primaquine can cause hemolytic anemia in persons with glucose-6-phosphate-dehydrogenase G6PD deficiency, persons must be screened for G6PD deficiency prior to starting these drugs. Screening for G6PD deficiency thus seemed pointless and was not routinely done by the US Army until about 2006. During the 1960s, primaquine therapy against relapse was routinely administered without knowing G6PD status of the patient. Providers were warned to be alert to the risk of haemolytic anaemia and to stop dosing with onset of signs.
