A member asked:
Will giving antiviral agent like valacyclovir later than 72 hours upon start of herpes zoster still be effective?
A doctor has provided 1 answer
Not usually: Herpes infections can be treated with antivirals such as Acyclovir and valcyclovir, but to really have an impact need to be started within 72 hours. Any later and the symptoms are really not effected much at all.
