Xerese cream contains a combination of acyclovir and hydrocortisone. Acyclovir is an antiviral medicine.

It reduces the actions of chemicals in the body that cause inflammation.

Herpes infections are contagious and you can infect other people, even while you are being treated with Xerese. Acyclovir and hydrocortisone will not prevent the spread of genital herpes. Avoid sexual intercourse or use a latex condom to prevent spreading the virus to others.
Xerese is for use for cold sores on the lips and around the mouth. This medication will not treat herpes lesions that affect the genitals or the eyes.
