Is valtrex (valacyclovir) or zovirax better for cold sores?

Either: I'm assuming you're talking about oral Valtrex (valacyclovir) and zovirax (not zovirax cream). Both are effective, but Valtrex (valacyclovir) is more convenient, because it doesn't have to be taken as frequently. My favorite way to treat cold sores is to have the patient take 2 grams of Valtrex (valacyclovir) at the very first sign of an outbreak, and then 2 grams 12 hours later. That two-dose course will shorten the duration of infection.

Neither: One med may not necessarily be better than the other. These are both antiviral medications of the same family. Kind of like the antibiotics Amoxicillin and penicillin the both work the same way. Valtrex (valacyclovir) or valcyclovir ends up being converted into zovirax or Acyclovir in your body when metabolized by your kidneys. Valtrex (valacyclovir) may cost more also.
