Although compulsive sexual behavior disorder (CSBD) is a relatively common disorder with an estimated prevalence of at least 3%, clinicians currently have limited evidence and no FDA-approved drugs to guide their treatment of this condition. N-acetylcysteine (NAC), an amino acid that seems to restore extracellular levels of glutamate in the nucleus accumbens, has previously demonstrated efficacy in treating multiple psychiatric disorders, including substance use disorders and putative behavioral addictions. However, no study has assessed the use of NAC (or any other glutamatergic agent, for that matter) in the treatment of CSBD. Here, we present data from a case series of 8 male patients with CSBD treated with NAC in routine clinical practice in a specialty outpatient clinic. Of these 8 patients, all of whom had previously been treated for CSBD with medications, therapy, or both, 5 had marked clinical improvement (>35% improvement on a modified version of Yale-Brown Obsessive Compulsive Scale) on NAC, and 3 showed minimal or no improvement (<15%). These findings suggest that NAC may be a potentially promising, well-tolerated treatment option for patients with CSBD, including those who have failed more traditional therapies.
