Summary

This trial compares two treatments for common and plantar warts: Microwave Treatment and Cryotherapy. Microwave Treatment uses heat to destroy the wart, while Cryotherapy uses freezing. The study aims to see which method is more effective and safe for patients.

Who is the study for?
This trial is for adults aged 22-64 with at least one significant common wart (3mm-10mm) or plantar wart (3mm-20mm), not mixed. Participants must stop current wart treatments 28 days before, avoid NSAIDs and antihistamines around treatment times, and commit to the study duration without using other wart products.
What is being tested?
The trial compares two treatments for warts: Microwave Treatment using the Swift system versus Cryotherapy. It's a randomized controlled study where participants are assigned to either method without knowing which group they're in but outcomes are assessed blindly.
What are the potential side effects?
Potential side effects of microwave therapy may include discomfort, skin irritation, or swelling at the treatment site. Cryotherapy can cause pain during application, redness, blistering, and possible scarring on the treated area.
