Abstract
Adderall (dextroamphetamine/ amphetamine) is a psychostimulant medication approved by the United States Food and Drug Administration for the treatment of attention deficit hyperactivity disorder. This medication is usually well tolerated with minimal side effects. We report a case of a 12- year-old girl who was prescribed Adderall by her primary care physician to treat her attention deficit hyperactivity disorder and who subsequently developed trichotillomania. A short time following the initiation of the medication, the patient's family members noticed the patient displaying unusual hair-pulling behavior. The patient was referred to a psychiatrist for an evaluation of trichotillomania. Following a thorough evaluation, the decision was made to discontinue the Adderall and switch the patient to guanfacine. The urge to pull her hair along with her anxiety dissipated following this change. Close followup was maintained for over a year with both the psychiatrist and the primary care physician, and during this time the patient did not display any unusual hair pulling behaviors. This case appears to display a very unusual side effect of Adderall.
