A Retrospective Review of Oral N-Acetylcysteine for Habit-Driven Cutaneous Disorders.

Oral N-acetylcysteine (NAC) has shown efficacy for debilitating habit-driven and neuropsychiatric disorders in small, mostly adult studies. We retrospectively evaluated the therapeutic use and safety of oral NAC in 93 children from the Children's Hospital of Philadelphia. This study supports the use of oral NAC for habit-driven skin, hair, and nail abnormalities in pediatric patients.
