Brand names: Denavir
Denavir cream is used to treat recurrent cold sores on the lips and face. It works by interfering with the growth of the herpesvirus responsible for the sores.
You should begin applying Denavir at the first hint of a developing cold sore. The drug will not cure herpes, but it will reduce pain and may speed healing.
Check with your doctor if your cold sore does not improve or becomes worse. You could have an infection.
Avoid using Denavir cream in or near the eyes; it can irritate them. Apply it only to sores on the lips and face.
Reactions to Denavir are quite rare. If any develop or change in intensity, inform your doctor as soon as possible. Only your doctor can determine if it is safe for you to continue using Penciclovir.
If you have ever had an allergic reaction to any of the ingredients in Denavir, you should not use Penciclovir.
It is not known whether Denavir is effective for people with weak immune systems.
No interactions with Denavir cream have been reported.
The effects of Denavir during pregnancy have not been adequately studied. If you are pregnant or plan to become pregnant, inform your doctor immediately. Researchers do not know whether Penciclovir will appear in breast milk after external application. For safety's sake, your doctor may advise you to discontinue breastfeeding your baby until your treatment with Denavir is finished.
ADULTS AND CHILDREN 12 TO 17 YEARS OLD

The safety and effectiveness of Penciclovir in children less than 12 years old have not been established.
There have been no reported overdoses of Penciclovir. Even if the cream is accidentally swallowed, it is unlikely to cause a harmful reaction.
