N-acetylcysteine (NAC) is a precursor to the aminoacid cysteine, a modulator of the glutamatergic system and has role in oxidative stress. 2 It has been shown that NAC is effective in various psychiatric problems especially in OCD and related disorders. 2–5 Here we report two cases with trichotillomania who were treated with NAC successfully. Case reports Our frst case was a 11-year-old girl with symptoms of eyebrow and eyelash picking for six months. After 3months of treatment wth risperidone (2,5mg/day) and fuoxetine (20mg/day) due to side-effects and low compliance NAC 600 mg/day monotherapy was started. The maintenance NAC dose was 1200mg/day. Her baseline and 2-months duration endpoint Clinical Global impression scale disease severity (CGI-S) score was 5 (markedly ill) and 1 (Normal, not at all ill) respectively. Our second case was a 16-year-old male patient with complaints of hair pulling for 2months. Due to experience adverse effects with fuoxetine 20mg/day NAC (600mg/day) was started as a monotherapy. The maintenance NAC dose was 1200mg/day. His baseline CGI-S score was 5. After 2months of NAC treatment, fnal score was 2 (borderline ill). Both of the cases responded well without any adverse effect. Conclusıon Although a recent study in pediatric trichotillomania, NAC showed no superiority over placebo in a randomized controlled add- on- trial; 2 symptom reductions are reported with NAC use pediatric case reports. 6,7 Our cases tolerated and responded well to NAC monotherapy. This report shows that NAC may be a safe choice in treatment of pediatric trichotillomania. Pharmacologic modulation of the glutamate system may prove to be useful in the control of other obsessive compulsive and related behaviors. Acknowledgments None.
