No evidence that chloroquine or hydroxychloroquine induce hemolysis in G6PD deficiency
Hydroxychloroquine and chloroquine have come under intense scrutiny over the past six months as they have been proposed as treatments for COVID-19. It is widely quoted and stated that the 4-aminoquinolines chloroquine and hydroxychloroquine cause oxidant hemolysis in glucose-6-phosphate dehydrogenase (G6PD) deficiency, yet there is no convincing evidence for this claim, and there is substantial evidence against it. X-linked G6PD deficiency is the most common human enzymopathy.
