Early treatment with IV acyclovir is recommended for infants in this exposure category who develop varicella despite VZIG prophylaxis.
However, if the case is particularly severe, the doctor may prescribe an antiviral medication such as acyclovir which, if given at the beginning of the outbreak, may help clear things up faster.
Antiviral pills such as acyclovir (Zovirax), famciclovir, (Famvir), and valacyclovir (Valtrex) can cancel an outbreak and help prevent recurrent outbreaks.
Acyclovir (Zovirax) is the drug of choice for herpes infection and can be given intravenously or taken by mouth.
Acyclovir is effective in treating both the primary infection and recurrent outbreaks.
