Q: What is acyclovir?
A: Acyclovir is a prescription antiviral drug that targets the herpes virus. Acyclovir can help minimize outbreaks of genital herpes and reduce the risk of spreading genital herpes to others. In addition, acyclovir promotes healing of chicken pox, shingles (herpes zoster), and cold sores (herpes labialis).
Q: What different formulations of acyclovir are available?
A: Acyclovir is sometimes sold under the brand name Zovirax. Acyclovir capsules, liquid, and tablets are used to treat genital herpes. Acyclovir ointment is prescribed to treat initial outbreaks of genital herpes and some herpes simplex infections of the skin and mucous membranes. Acyclovir cream is prescribed for cold sores on the lips and face only.
Q: Will Acyclovir cure my genital herpes?
A: No. Acyclovir does not cure genital herpes. In fact, there is no known cure for genital herpes. However, acyclovir can reduce the frequency of genital herpes outbreaks. During an outbreak of genital herpes, acyclovir provides pain relief and speeds up healing.
Q: Can acyclovir help me avoid giving genital herpes to my partner?
A: When used daily (as opposed to only when an outbreak occurs), acyclovir can reduce the risk of spreading genital herpes to your partner. Along with a daily dose of acyclovir, always use latex condoms to minimize the risk of spreading genital herpes. To reduce the chance of infecting your partner, avoid intercourse and other sexual contact while you have sores or any other symptoms of a genital herpes outbreak.
