Denavir (penciclovir): “Finally a medication that truly delivers on its claim! Clears up cold sores within a day or two if caught early, otherwise, still provides relief and shortens duration. This stuff works!!!”

Denavir (penciclovir): “I've gotten cold sores since childhood 40+ years ago. I've tried many remedies, Denavir is by far the best I've ever used, especially when used at the first sign of an outbreak.”

Denavir (penciclovir): “Best cold sore medication ever. I have tried everything, this stops it from growing right away so they don't last near as long.”

Denavir (penciclovir): “Denavir, for me, does not work. It does not stop the cold sore formation and does not heal it quickly. It has taken nearly 2 weeks for my cold sore to heal.”

Denavir (penciclovir): “I get cold sores frequently in fall and winter. Denavir is wonderful! When I use it at the first sign, sometimes it doesn't even develop into a cold sore. I always keep this on hand.”
