  • Patients with ED’s are more susceptible to adverse side effects, especially if they are purging or if they are at a low weight. START LOW AND GO SLOW!
  • Psychotropic medications do not work as well when nutrition status is poor.

  • Patients may begin to experience side effects when they are adequately weight restored possibly due to surge in neurotransmitters
