1. Following liquid nitrogen treatment, it is usual to experience pain for a few minutes. If the pain is severe, you should take a mild pain medication such as Tylenol in the appropriate dosage.
2. Within the first 24 hours following treatment, the area may develop a brown, black, or red crust, or it may blister. The blister may contain clear fluid or blood and may appear as a purplish grape-like lesion. If it is uncomfortable, you may carefully pierce it with a sterilized needle.
3. After the blister or crust forms, (usually in a week), apply a topical antibiotic (polysporin/bacitracin) to the area twice a day for the next three weeks.
4. The crust usually peels off after two or three weeks. If residual wart, actinic keratosis, etc. is present after the peeling, more treatment will be needed.
5. If there are any questions following cryotherapy, you should EMAIL staff@cdermatology.com.
