What are some of the most common adverse reactions associated with cantharidin?

Warts And Molluscum

White anth, as many of you know, is a vesicin agent, and therefore blistering is a potential adverse event that we see just from the medication use on its own. With any clinical trial we do investigate and we study any unwanted adverse events such as blistering, but also pain and itch and discomfort at the treated site. So those are other potential adverse events that could be seen. What we did not see is significant scarring in the study and for the patients that were enrolled with higher Fitzpatrick types in skin of color, there was not an increased amount of adverse events regarding post inflammatory hyper or hypopigmentation that was not noted to be an outlier.
