Efficacy Study of add-on Therapy With N-Acetylcysteine in Resistant Obsessive-compulsive Disorder

Summary

The primary objective of this study is to determine if N-Acetylcysteine (NAC) has efficacy as an augmentation agent in the treatment of treatment-resistant obsessive-compulsive disorder (OCD). The investigators predict that NAC will reduce OCD symptoms after sixteen weeks of add-on treatment as measured by the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS).
