Unraveling the complexity: Case reports of drug-induced hemolytic anemia due to ceftriaxone

Drug-induced hemolytic anemia (DIHA) is a rare but significant condition characterized by the premature destruction of red blood cells (RBCs) triggered by certain medications. Ceftriaxone, a commonly used antibiotic, has been linked to DIHA, presenting diagnostic challenges due to its diverse clinical manifestations. This study examines three cases of DIHA caused by ceftriaxone therapy at our center. The patients presented with symptoms such as fatigue, jaundice, and dark urine following ceftriaxone therapy. Laboratory tests indicated hemolytic anemia with decreased hemoglobin, elevated lactate dehydrogenase, and positive direct antiglobulin tests. Immunohematological workups confirmed ceftriaxone-induced antibodies targeting RBCs and guided management strategies, including discontinuation of ceftriaxone, supportive therapy, and corticosteroids. Timely diagnosis and collaboration between clinicians and laboratory specialists are crucial for optimal patient outcomes.
