A Pilot Open-labeled Trial of S-adenosyl Methionine (SAM-e) for Recurrent Abdominal Pain in Children

This pilot study will investigate the efficacy of SAM-e for the treatment of recurrent
abdominal pain in children. This will be an open-labeled study and all participants will
receive SAM-e therapy. Given that SAM-e has been demonstrated to improve symptoms of
depression and pain with minimal side effects as compared to other antidepressant therapy, we
hypothesize that SAM-e will reduce pain symptoms among children with recurrent abdominal
pain.
