What is nonsurgical nail removal?

Nonsurgical (chemical) nail removal is a painless procedure for a fungal nail infection. This technique removes only the diseased and damaged nail, not the healthy part of the nail. It is done in a clinic or your doctor's office. Either the entire nail (avulsion) or part of the nail (debridement) can be removed. This procedure is almost always painless.

Your doctor will first place cloth adhesive tape on the normal skin around the infected nail. A urea ointment is then put directly on the nail surface and covered with plastic and tape. The ointment softens the nail over the next 7 to 10 days. You must keep the nail and dressing dry during this time.

After the nail softens, your doctor removes the treated nail by lifting the nail away from the nail bed or by cutting out the diseased portion of the nail.

Nonsurgical nail removal can be used for severe antifungal infections and on nails that have increased in size due to abnormal growth (hypertrophic). It is rarely necessary.
