Common Questions and Answers about Acyclovir vs famciclovir


Avatar n tn The antiviral medications available to treat genital herpes are acyclovir, famciclovir (Famvir), and valacyclovir (Valtrex). Acyclovir has the most data on the safety of use in pregnancy. A registry of over 1000 pregnant women who were exposed to acyclovir during early pregnancy suggests that acyclovir is probably safe as there were no increases in birth defects.
Avatar m tn Before the acyclovir I was on 500 mg of Valtrex once daily but my insurance made me change to acyclovir. So far it has not. The Valtrex was working well and so was the acyclovir (I was having outbreaks about every other month) until about 2 months ago. When you say HIV is a long shot risk (a very long shot) how concerned should I be? I assume you mean that it is unlikely that I have HIV? How reliable is the type of HIV test I took?
Avatar n tn as you may know, such infections are more common in diabetics than people without diabetes. None of the antiherpes drugs (acyclovir, valacyclovir, famciclovir) will interfere with your diabetes drugs. Presumably you are on acyclovir now? If not, get a prescription right away; it will help speed healing of your herpes. All three drugs are equally effective in preventing future outbreaks; the differences are in dosing frequency and cost.
Avatar n tn You're right that suppressive therapy isn't used as often for oral vs genital herpes. That's because most people with recurrent oral herpes don't have as frequent outbreaks as genital HSV-2; and oral herpes usually isn't associated with the psychological/social stress of genital, so people's thresholds for effectiveness, cost, and convenience are different. But it works just fine--although the dose for effective suppression is higher than for genital HSV-2.
