Which of the following treatments has the strongest evidence for reducing hair pulling urges in trichotillomania?
The answer is D. Although there is no current universally accepted first-line treatment for trichotillomania, the glutamatergic agent, N-acetylcysteine (NAC), dosed at 1200 mg bid has been demonstrated to be helpful in reducing urges to hair pull. It is generally safe and well-tolerated. The most common side effects are flatulence and bloating. There is no strong evidence for the use of SSRIs in trichotillomania.
