What should you know about electrocautery machine for warts?

The machine sends electrical energy through a treatment handpiece. The clinician selects settings and applies the tip to the wart after cleaning and numbing the skin. Heat can destroy the visible wart and help control bleeding at the treatment site. The treated area may form a crust or shallow wound while it heals.

Warts are caused by a viral infection in the skin, so removing the visible tissue does not always prevent another wart from appearing. A clinician may choose electrocautery, freezing, a prescription treatment, or another method based on the wart’s location, thickness, number, and your health.

Tell the clinician about poor circulation, diabetes, reduced immunity, medicines that affect bleeding, and any implanted electrical device. Do not shave, scratch, or share towels and nail tools over the wart. After treatment, keep the site clean and covered as advised, avoid picking the crust, and wash your hands after touching the area.

Seek advice if pain, swelling, warmth, or drainage increases, or if the wound bleeds repeatedly. Fever, spreading redness, or difficulty using the affected hand or foot warrants prompt review. Have a wart reassessed if it changes, bleeds without injury, or fails to behave like the diagnosis given.

Ask how the diagnosis was made, why electrocautery is preferred, whether a sample is needed, and how the treatment may affect nearby nails or sensitive skin. Clarify wound care, return-to-activity guidance, recurrence, and alternatives such as cryotherapy or prescription treatment.
