Analysis of over-the-counter products marketed to treat molluscum contagiosum.

Many over-the-counter (OTC) products are marketed to treat molluscum contagiosum, a common childhood viral infection with an estimated point prevalence of 5%-11%. As optimal treatment has not been defined, a comprehensive internet search was performed to identify OTC products marketed for treating molluscum and to collect information on packaging, ingredients, application instructions, and dosing. Nine OTC products were identified and varied widely in cost, packaging size, and ingredients; six of the nine products contained Thuja occidentalis. Overall, the majority of OTC package labels do not include sufficient information about their plant-based ingredients or appropriate dosing.
