Denavir is a topical antiviral medication used for recurrent cold sores (herpes labialis) on the lips and face in otherwise healthy adult patients. It is applied externally on the lips and face. It is not indicated for internal use on mucous membranes inside the mouth, nose, genital or rectal areas.

Denavir Side Effects:

Denavir has been shown to heal cold sores on average in four and a half days. It has also been shown to reduce the lesion pain by about one-half-day when compared to placebo. However, always consult with your physician or dentist for information on your particular situation.

Apply Denavir every two hours during waking hours for four days to your cold sore with your finger or a cotton swab. Wash hands with soap and water to prevent it from coming into contact with your eyes or other areas to prevent irritation and to prevent spread of the herpes virus.
