Why acyclovir is not working?
In some cases, herpes flare-ups do not respond to acyclovir, valacyclovir or famciclovir, probably due to resistant forms of HSV-1 and HSV-2. People living with HIV with suppressed immune systems—CD4 counts below 100—who have been on long-term acyclovir have developed drug-resistant herpes.
