When I started prophylactic treatment with acyclovir, I saw a reduced occurrence for a few months, then they came back to about 4-5 outbreaks/year. I recently switched prophylactic medication from acyclovir to
famciclovir, and had a 18-month period free from outbreak. Come yesterday, I had another terrible outbreak (worse than usual)... will these become more commonplace now? Is this a sign of HSV-resistance to the drug? Are there any other courses of action I can consider?
