Read this Patient Information before you start taking FAMVIR and each time you get a refill. There may be new information. This information does not take the place of talking with your healthcare provider about your medical condition or treatment.
What is FAMVIR?
Famvir is a prescription antiviral medicine used to:
- treat outbreaks of cold sores (fever blisters) in healthy adults
- treat outbreaks of genital herpes in healthy adults
- decrease the number of outbreaks of genital herpes in healthy adults
- treat outbreaks of herpes simplex lesions in or around the mouth, genitals, and anal area in people infected with HIV
- treat shingles (herpes zoster) in adults with normal immune system
It is not known if FAMVIR is safe and effective in children younger than 18 years of age.
FAMVIR is not a cure for herpes. It is not known if FAMVIR can stop the spread of herpes to others. If you are sexually active, you can pass herpes to your partner even if you are taking FAMVIR. Herpes can be transmitted even if you do not have active symptoms. You should continue to practice safer sex to lower the chances of spreading genital herpes to others. Do not have sexual contact with your partner during an outbreak of genital herpes or if you have any symptoms of genital herpes. Use a condom made of latex or polyurethane when you have a sexual contact. Ask your healthcare provider for more information about safer sex practices.
Who should not take FAMVIR?
Do not take FAMVIR if you are allergic to any of its ingredients or to Denavir® (penciclovir cream). See the end of this Patient Information leaflet for a complete list of ingredients in FAMVIR.
