Penciclovir belongs to the family of medicines called antivirals. Antivirals are used to treat infections caused by viruses. Usually they work for only one kind or group of virus infections.
Topical penciclovir is used to treat the symptoms of herpes simplex virus infections around the mouth (cold sores). Although topical penciclovir will not cure herpes simplex, it may help relieve the pain and discomfort and may help the sores heal faster.
