Treatment for both conditions
According to Dr. Grant, the treatment of choice for skin-picking disorder and trichotillomania is a specific psychotherapy known as “habit reversal therapy,” which involves helping the patient gain better self-control. The drawback is that it’s difficult to find someone trained in habit reversal therapy, “who know anything about skin picking and hair pulling,” he said. “That has been a huge challenge in the field.”
In his experience, the medical treatment of choice for skin-picking disorder and trichotillomania is N-acetylcysteine, an over-the-counter amino acid and antioxidant, which has been shown to be helpful at a dose of 2,400 mg per day. “Patients report to me that some of the excoriations clear up a little quicker as they’re taking it,” Dr. Grant said.
There may also be a role for antipsychotic therapy, he said, “but because of the associated weight gain with most antipsychotics we prefer not to use them.”
The opioid antagonist naltrexone has been shown to be effective in the subset of patients with skin-picking or hair-pulling disorders whose parents have a substance use disorder, Dr. Grant said. “The thought is that there’s something addictive about this behavior in some kids. These kids will look forward to picking and find it rewarding and exciting.”
