Sumario: | Perampanel (Fycompa) is a glutamate receptor antagonist known to be a safe, effective, and well-tolerated medication; nevertheless, adverse effects are possible. This case report aims to raise the suspicion of perampanel-induced thrombocytopenia and discuss its possible pathways implicated. Here, we present the case of a 66-year-old female patient with a generalized tonic-clonic seizure initially managed with levetiracetam, valproic acid, and lacosamide; however, the patient continued to have seizures clinically as well as on the electroencephalogram. The patient was initiated on 2 mg of perampanel and reached up to 12 mg within a week, after which the seizure was controlled. Nevertheless, after perampanel initiation, a gradual platelet count reduction was observed. Upon withdrawal of perampanel, the platelet count dramatically improved reaching up to her baseline. Although perampanel is known to be a safe medication, a hematological complication such as thrombocytopenia is possible. The exact mechanism remains unclear. Further studies are required to understand the association between thrombocytopenia and perampanel to identify high-risk populations and prevent this condition sequentially. |
