u/Sufficient-Ad-197

Never had a cold sore before but my whole family gets them on mom/dad side. I have always been very cautious about not drinking/eating after any of them, even when they don’t have an outbreak. In April, I had my first cold sore. Tried Abreva and cold sore patches and it went away after 2 weeks. A week later, another one popped up in the same place. It’s been there for a month. Tried 3 different brands of patches & Abreva and still has no sign of going away. My doc prescribed Valacyclovir 3 weeks ago and said to take it before my next flare up. Could I take it now? Nothing else is working.
