Ycanth is indicated for the treatment of molluscum contagiosum, a common viral skin infection that causes small, flesh-colored bumps, particularly in children and immunocompromised individuals.
Cantharidin, the active ingredient, causes acantholysis (separation of epidermal cells) leading to blister formation beneath the molluscum lesion. This process helps detach and eliminate the infected tissue.
Ycanth is applied in a healthcare setting and washed off after a specified time. Common side effects include blistering, redness, and temporary skin discoloration at the application site. It should not be used near the eyes, mouth, or genital area. Only a healthcare professional should apply this medication.
