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

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. ...Read more

Zovirax (acyclovir) vs. Vectavir. Which is better?

Cream or oral?: Vectavir (penciclovir) is a cream for herpes. Zovirax (acyclovir) is available both as a cream and pills to be taken by mouth. Neither cream works very well; if herpes treatment is needed, pills are always best. In other words, Vectavir and Zovirax creams are both poor treatments, but Zovirax pills usually are very effective. ...Read more

Is abreva good for genital herpes?

Not so good: Docosanol (Abreva) has little if any effect against herpes outbreaks. It somewhat inhibits the virus in the lab, but has little benefit in shortening outbreaks. (The same is true for all creams or ointments, such as acyclovir or penciclovir, even though these are far more potent than docosanol against the virus.) Effective treatment requires oral therapy, e.g. valacyclovir or acyclovir. ...Read more

How can reduce transmission of herpes to my bf? I am on Valtrex (valacyclovir) and use latex condoms but there is still risk :(

Low risk: By being on Valtrex (valacyclovir) and using condoms, you're greatly lowering the risk. You can't do much more than that short of abstinence. Keep in mind that he could already have been infected, even if he has no outbreaks. The only way to find out would be with an hsv-2 antibody test. But since you're already taking valtrex, (valacyclovir) i'm not sure the information would help. ...Read more
