摘要
Both dapsone and primaquine are oxidant drugs that can cause hemolytic anemia in G6PD deficiency and methemoglobinemia in other patients. Together the oxidative stress is additive, and the risk of hemolysis is higher.
用白話說明這項交互作用的意義
Dapsone and Primaquine can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
