Is duct tape effective for treating warts?
* Clinical question
Is duct tape an effective treatment for common viral warts in adults?
* Bottom line
No--occlusion with duct tape was no more or less effective than occlusion with moleskin. The low success rate overall argues against any effect for occlusion.
Level of evidence
1b: Individual randomized controlled trial (with narrow confidence interval)
Randomized controlled trial (single-blinded)
Previous small studies have suggested that duct tape is at least as effective as cryotherapy for the treatment of common viral warts. However, in the most widely reported study, blinding was uncertain and follow-up incomplete.
In this study, 90 adults with 126 warts were randomized to occlusive therapy with either duct tape or moleskin. Blinding was accomplished by having the duct tape applied to the interior (adhesive) side of the moleskin, keeping the external surface identical in both groups. The protocol involved shaving the wart with a scalpel, applying the pad for a week, then debriding it lightly with an emery board and reapplying the pad for I additional week. This was repeated for a total of 2 months or until the wart resolved.
Patients were called 6 months later to see if the wart had recurred. Groups were similar at baseline (mean age=54 years, 72% male) and analysis was by intention to treat; 5 patients in each group were lost to follow-up. At the end of the initial 2-month treatment period, there was no difference in the likelihood of wart resolution (21% vs 22%) or recurrence.
