Drug-induced immune hemolytic anemia occurs when certain medications trigger antibodies to attack red blood cells. Drugs that impair metabolism of folic acid or interfere with absorption of vitamin B12 may induce megaloblastic anemia.
Management first begins by withdrawing the causative agent (may involve changing to another medication). Depending on the type, severity, and bodily systems involved, treatment may include pharmacotherapy such as glucocorticoids, erythropoietin-stimulating agents (ESAs) and other drugs, recombinant erythropoietin, careful monitoring, and transfusion.
