A member asked:
Is abreva and denavir (penciclovir) the same?
A doctor has provided 1 answer
Different: While they are both topical treatments for cold sores (herpes simplex), they are different medications. They both may shorten the duration of an active cold sore outbreak somewhat, but through different mechanisms. Abreva has an advantage in that it is available without a prescription.
