Valproate Induced Hyperammonemic Encephalopathy.

Valproate is a commonly prescribed anticonvulsant drug. It has a potential to cause hyperammonemia even in the presence of normal liver function tests. This hyperammonemic state can lead to encephalopathy referred as Valproate induced hyperammonemic encephalopathy (VHE). Here we present a case of valproate induced hyperammonemic encephalopathy in a young male caused by initiation of valproate therapy.
