Valacyclovir
"I have HSV 2 since about 22 and at about age 26 Valtrex became available. I have taking 1 gram daily (somewhat consistent) until about about 2.5years ago. It was great, and I didn't have one single outbreak in almost 14 years, nor did my two long term ex's get the virus. Unfortunately, I developed an allergic reaction from long term use, and can no longer tolerate it without major skin rash, major itching, hypersensitivity and also had some hair thinning. I'm trying Famvir, but so far I'm back to having outbreaks. I have gone on and off the medicine 6-7 times and within weeks have had negative symptoms, which subside within days of discontinuing. "
