Chemical Cauterisation

Chemical cauterisation plays a major part in the treatment of verrucae. The two agents used at this clinic are Salicylic Acid and Silver nitrate.

This treatment offers minimum discomfort to the patient. As the treatment progresses and the verrucae become shallower there may be some pain. The aim of this treatment is to burn away the verruca and a thin layer of underlying tissue, causing a blister or small wound.

For young children and those whose pain threshold is low, this would be the treatment of choice. The number of treatments varies depending on the depth and size of the verruca. However, it is recommended a course of 3 treatments is initially taken.

Chemical Cauterisation


The verrucae will first need to be debrided by the podiatrist. The area is then masked off with an aperture pad and salicylic acid – or both silver nitrate and salicylic acid – is applied to the verruca within the aperture of this pad. This is then covered by a dry dressing and a deflective pad if needed.

For the most beneficial results, we recommend that the gap between treatments be minimal ie once every week initially. This may be increased to once every two weeks depending on the podiatrist’s assessment of the lesion.

Not generally. The callused skin within a verruca has no nerve endings. However, once the verruca becomes
shallower and the surrounding skin is cauterised, there may be some short-lived discomfort.
