Acyclovir and Hydrocortisone

Overview

Acyclovir and hydrocortisone is a topical combination medicine that is dispensed in the form of a cream and is used for the treatment of painful, unsightly vesicles (cold sores) around the lips, mouth, nose, and nasal septum.

The medication will not cure the herpes simplex virus that causes the vesicles to develop, but it may help the sores to heal more quickly and it can also relieve the itching, tingling, pain, and discomfort that they cause to sufferers.

Acyclovir is an antiviral agent that treats the virus and works to prevent it from spreading. Hydrocortisone is a steroid preparation that aids the healing of the skin and relieves the pain and inflammation caused by the sores when they emerge.

This medication is known under the brand name Xerese in the U.S. and is available only on prescription from a doctor or other health professional.
