Why is premaquine not good for haemolytic patients?

G6PD: Primaqunie will cause red cells to hemolyze if the person has g6pd deficiency. Other patients with hemolysis from some other cause can take it.

Beacause: It causes hemolysis or destruction of red blood cells specially people with g6pd deficiency. Hemolytic anemia due to any disease or cause is already destroying rbcs. If you give primaquine, you double or triple the destruction and can have life threatening anemia. It also causes methemoglobinemia. Thanks.
