Answer

The 2001 AAN practice perameter suggested that the use of acyclovir for the treatment of Bell palsy is only possibly effective and that therapy with this agent alone is not effective in facial recovery. [45] According to the academy's 2012 guidelines, benefit from antivirals has not been established and, at best, is likely to be modest. [6, 8]
