herpes simplex
"I am extremely annoyed I was diagnosed with HSV when I was 8. For the past 18 years I've had breakouts on and off. First I was prescribed Famvir then Acyclovir. I haven't had a breakout in over two years. When I unexpectedly had this recent breakout my prescription was expired. I was advised to use Abreva. It stung but helped dry up the blister but made the swelling worse. When my prescription was filled the medicine did its job. However the Abreva burned my lip and I now have a visible scar on my upper lip. I will never again use Abreva"
