that causes a blister to form on the wart or growth. This action lifts the wart off the skin and after a few days when the blister has dried the wart will come off. The action of cantharidin does not go beyond the epidermal cells, the basal layer remains intact hence no scarring.

How long does it take for cantharidin to work?

A blister will form within 24–48 hours. Over the next few days, the blister will dry and the lesion may fall off. If necessary the blistered lesion can be snipped off near the base (local anaesthetic may be required). Healing is normally complete within 4–7 days.

“The cantharidin causes cells to release an enzyme that breaks down proteins in desmosomal plaques, specific structures involved in cell-to-cell adhesion. That is, it breaks the bonds that hold skin cells together,” explains Dr. Mamelak. The resulting blister forces the wart or skin growth off of the skin.
