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.

VIRAL INFECTIONS. Viruses can promote worsening of ms, even a full blown relapse. Sounds like you recently had labor and delivery, and pregnancy is protective, but breastfeeding is not so protective, and you may indeed have an emerging relapse or progressive symptoms. The long and short here is the need to see a neurologist and restart a potent disease modifying drug. Do not worry about which viral drug is used. Read more...

I've been having cold sores for about 2 months and been taking acyclovir and then Valtrex (valacyclovir) should I see an infectious disease doctor?
