Hyperammonemia manifests clinically as mild cognitive impairment to coma and even death. It happens due to both hepatic metabolic disorders or non-hepatic causes. Perampanel is an antiepileptic drug metabolized by hepatic enzymes.We here report a patient of CNS lupus who presented with NCSE and developed hyperammonemia after receiving the loading dose of perampanel. No definite mechanism has been able to explain the correlation between perampanel and hyperammonemia. The blood ammonia levels came down to the normal range after stopping the medication. However, even after the stoppage of perampanel and normalization of ammonia, her condition and NCSE remains the same. We suggest serum ammonia levels should be done before starting perampanel in any patient with a constant monitoring of ammonia levels at regular intervals. However, more cases are required to understand the mechanism of action, risk factors and establish monitoring protocols in patients for perampanel therapy.
