Indications
Denavir cream (penciclovir) is a prescription medication used to treat cold sores (herpes labialis) caused by the herpes simplex virus. Penciclovir belongs to a class of medications known as antivirals. It works by preventing the herpes virus from multiplying, thereby reducing the duration of outbreaks and easing symptoms like tingling, itching, redness, and swelling.
Denavir can be used to treat cold sores on the lips that are caused by the herpes simplex virus. It is for adults and children who are at least 12 years old. It is not a cure for herpes and cannot prevent the spread of the virus to others. Patients should consult with their healthcare provider for more information about using Denavir cream for cold sores.
