Molluscum Contagiosum
Molluscum contagiosum is a common, contagious skin infection caused by the molluscipoxvirus. There are currently no FDA-approved therapies for molluscum, and upon seeking treatment, caregivers are faced with potentially painful in-office, dermatologist-administered physical procedures or cantharidin, or recommended off-label prescriptions and over-the-counter products. More than half of the patients diagnosed with molluscum are untreated and over 30% of those treated receive an off-label prescription with no molluscum indication or proven clinical efficacy. The average time to resolution is 13 months, however, some children experience lesions that may not resolve in 24 months.
