Hematological Toxicity of Antiepileptic Drugs
Summary
Antiepileptic drugs (AEDs) are central to the management of seizure disorders but carry a recognised risk of haematological toxicity. This encompasses disturbances in blood cell lineages—red cells, white cells and platelets—and impairments of coagulation pathways. Clinical presentations range from mild thrombocytopenia or isolated neutropenia to severe bone marrow suppression manifesting as pancytopenia. Mechanistic studies have identified direct drug effects on precursor cells within the bone marrow, immune‐mediated destruction, and interference with intracellular signalling that governs cell survival and apoptosis. Valproic acid is frequently implicated in coagulopathies and thrombocytopenia, while carbamazepine has been shown to trigger platelet apoptosis via kinase modulation. Less common but serious adverse events include agranulocytosis, aplastic anaemia and hypofibrinogenaemia. Vigilant monitoring of full blood counts and coagulation profiles remains essential, with prompt dose adjustment or drug withdrawal upon detection of significant abnormalities. Understanding these toxicities is vital not only for optimising antiepileptic therapy but also for minimising bleeding risks in perioperative settings and improving long‐term outcomes for patients worldwide.

Hematological Toxicity of Antiepileptic Drugs publication trend
The graph below shows the total number of articles in hematological toxicity of antiepileptic drugs across all publications each year (not limited to Nature Index journals).
Technical terms
Thrombocytopenia: A reduction in circulating platelet count below normal limits, increasing bleeding risk.
Pancytopenia: Concurrent deficiency of red cells, white cells and platelets, often indicating bone marrow failure.
Coagulopathy: Impairment of the blood clotting process, which may result from factor deficiencies or platelet dysfunction.
Platelet apoptosis: Programmed cell death of platelets, leading to their premature removal from circulation.
Protein kinase A (PKA): An enzyme that regulates cell survival signalling; its inhibition can trigger platelet apoptosis.
