A. Agranulocytosis: Carbamazepine carries a boxed warning for serious hematologic effects, including agranulocytosis and aplastic anemia. Agranulocytosis is a significant drop in white blood cell count, leading to a high risk of infection.
B. Birth defects: While carbamazepine is associated with birth defects when taken during pregnancy, the boxed warning specifically highlights the risk of severe blood disorders like agranulocytosis.
C. Skin rash: Carbamazepine can cause serious skin reactions, including Stevens-Johnson syndrome and toxic epidermal necrolysis, but the boxed warning focuses more on the hematologic risks.
D. Liver damage: Although carbamazepine can cause liver damage, this is not the primary focus of the boxed warning, which emphasizes hematologic effects.
