Acyclovir and amantadine have had limited use in treating ISSHL, presuming a viral etiology. Two newer agents, famciclovir and valacyclovir, have not yet been reported upon as treatment for sudden hearing loss. They are structurally similar to acyclovir, affecting viral thymidine kinase. They inhibit viral DNA polymerase, preventing viral DNA replication.
