Consultant360Topical Treatment for Molluscum Contagiosum in Adults, Children Approved by FDA

Molluscum contagiosum manifests as white, pink, or flesh-colored bumps on the skin.

The FDA has given its nod to cantharidin, the inaugural topical treatment for molluscum contagiosum in both adults and pediatric patients aged 2 years and above, marking a significant advancement in dermatological care.

Key Points:

  • Cantharidin is a topical solution exclusively administered by health care professionals.
  • The approval was based on two double-blind, randomized, placebo-controlled trials involving 528 participants aged 2 to 60 years.
  • 54% of cantharidin-treated subjects achieved complete clearance of molluscum bumps by day 84, in contrast to 13% in the placebo group.

Additional Points:

  • Treatment was given at 21-day intervals, up to a maximum of four applications.
  • Adverse events at the application site encompassed blistering, pain, itching, scabbing, reddening, discoloration, dryness, swelling, and skin erosion.
  • Oral administration is contraindicated due to potential severe or fatal toxicities.


  • Cantharidin offers a promising solution for molluscum contagiosum, with over half of the treated subjects achieving complete clearance, though care must be taken due to potential adverse effects.
