It's weird. I have herpes type 1, which is cold sores, not genital warts. The thing is, I had a genital outbreak of it. My boyfriend had a cold sore, or really just the beginnings of one as I didn't notice until the next day, and we were...intimate. I started breaking out a while later, but it came with an allergic reaction I started having to antibiotics I was on. I went to the er because of the reaction and I asked about the break out down south because it didn't look like hives. They said it was folliculitis...inflamed hair follicles. It wasn't going away, so I went to my ob/gyn. She wasn't sure, so she took a swab. Sure enough, she called me and said it was odd, but possible obviously, gave me Valtrex. I was told since it wasn't genital herpes, it would probably never break out down there again that way. It's been over 2 years since then, never happened again until the other day. A small area broke out in a few tiny sores. My Valtrex is expired, but I took one anyway. How dangerous is it to take an expired Valtrex?
