My cold sore is hideous. It's black and thick and nasty. My Doctor prescribed me valtrex for it. Will it help to take it now that it's already scabbed over?
It would depend on how many days you have had the cold sore. If it was your first herpes outbreak, it will more than likely be the most severe. You should now take Valtrex everyday to avoid future outbreaks and/or to make future outbreaks shorter and less potent. For example I had an initial outbreak of herpes zoster (shingles) on my neck 40 years ago. I became really stressed out last July and BINGO got shingles again on my neck but the other side. I shaved around it and got to my doctor asap. It never broke the skin or began weeping liquid. I had been taking Valtrex prophylactically for years but stopped two years ago. I was lucky that the shingles outbreak wasn't worse than it was. Be advised that any open herpetic sore anywhere on your body while weeping or exuding pus will give anyone who comes in contact with it the herpes virus, so be careful now and in the future.
