What is XERESE?
- XERESE is a prescription medicine used in people 6 years of age and older to shorten the healing time of cold sores (herpes labialis) and lower the chance of a cold sore becoming worse (ulcerating).
- XERESE is not a cure for cold sores.
- It is not known if XERESE is safe and effective in children less than 6 years of age.
What should I tell my healthcare provider before using XERESE?
Before using XERESE, tell your healthcare provider about all of your medical conditions, including if you:
- become sick very easily (have a weak immune system)
- are pregnant or plan to become pregnant. It is not known if XERESE will harm your unborn baby.

Tell your healthcare provider about all the medicines you take, including prescription and over-thecounter medicines, vitamins, and herbal supplements.
How should I use XERESE?
- Use XERESE exactly as your healthcare provider tells you to use it.
- Use XERESE as soon as you have the first symptom of a cold sore such as itching, redness, burning or tingling or when the cold sore appears.
- Apply XERESE over the affected area, including the outer edge of the cold sore.
- Do not rub the cold sore because this may cause the cold sore to spread to other areas around your mouth, or make your cold sore worse.
- Do not cover the cold sore or the area around the cold sore with a bandage.
- Do not use other skin products (such as make-up, sun screen or lip balm) or other skin medicine on the cold sore or the area around the cold sore.
