Some warnings and precautions to be aware of with this drug include the following:
- This medication should only be used on the lips or the skin around the mouth. Do not use it in the mouth, nose, or eyes, or on the genitals. Xerese should not be used to treat genital herpes.
- Xerese works best when started at the first signs of a cold sore. Try to use the medication at the earliest signs of an outbreak.
