USES: This medication is used to treat "cold sores/fever blisters" (herpes labialis). It can speed up healing of the sores and decrease symptoms (such as tingling, pain, burning, itching). Penciclovir belongs to a class of medications known as antivirals. It works by stopping the growth of the virus. This medication does not cure herpes, and it does not prevent passing the infection to someone else. It does not prevent future occurrences.

HOW TO USE: Use this medication at the first sign of infection (such as tingling, burning, redness, or sores). Wash your hands with soap and water before and after applying this medication. Clean and dry the affected areas before applying the medication. Apply a thin layer of penciclovir cream to completely cover the area of the cold sore or the area of tingling/itching/redness/swelling, and rub in gently. Apply the cream every 2 hours (except during sleep) for 4 days or as directed by your doctor.Apply to skin only.
