Mefenamic acid triggered autoimmune hemolytic anemia in a child: a rare case report

Autoimmune hemolytic anemia (AIHA) is characterized by the abnormal production of antibodies that bind to antigens on the surface of red blood cells (RBC), resulting in RBC destruction. Here we describe a rare case of mefenamic acid-induced AIHA in a 3-year-old boy who developed acute hemolysis after ingestion of mefenamic acid for febrile illness. The aim is to draw the attention of pediatricians to one of the side effects of mefenamic acid, the drug which is very commonly used as an antipyretic.
