Empiric therapy for encephalitis includes Acyclovir and it should be administered to all patients with suspected encephalitis as early as possible to reduce the risk of neurologic sequelae.  Doxycycline should be added to the empirical regimen if epidemiological or clinical clues suggest rickettsial or ehrlichial infection.  Despite the wide range of viruses that cause encephalitis, specific antiviral agents are generally limited to infections caused by the herpesviridae and human immunodeficiency virus (HIV).  Treatment for other viral encephalitis is largely supportive.
