Acute Levetiracetam-Induced Thrombocytopenia in an Anticoagulated Immunocompetent Patient.

Levetiracetam (LEV) is a commonly prescribed anti-seizure medication for the prophylaxis and treatment of focal and generalized seizures. However, a few significant LEV-associated adverse effects have been reported in the literature. Here, we describe a case of significant thrombocytopenia within 24 hours of IV LEV administration for generalized seizures in an anticoagulated immunocompetent patient that completely resolved following discontinuation of the medication.
