Verrutop has been regularly used in a number of European settings for several years and whilst much of the published clinical data spans all aspects of HPV wart therapy from a dermatological perspective there have been a number of standalone reports looking specifically at ano-genital warts which bolster the specific use of Verrutop in this field.
The most recent study, a single blinded RCT post-dates the publication of the EADV Position document.
Verrutop has an impressive and increasing range of clinical studies to support its introduction.
