  • DSM-IV diagnosis of Rett's disorder or childhood disintegrative disorder
  • Presence of extreme aggression or self-injury
  • Currently taking an effective psychotropic drug
  • Currently using other medications that may be unsafe to take with atomoxetine (e.g., potent CYP 2D6 inhibitors, intravenous albuterol, monoamine oxidase [MAO] inhibitors)
  • Inability to swallow study medication
  • Presence of a medical condition that would make treatment with atomoxetine unsafe (e.g., unstable hypertension or cardiac disease, asthma requiring frequent treatment with albuterol, narrow angle glaucoma, pregnancy, etc.)
  • Mental age of less than 18 months
  • Previous adequate trial of atomoxetine
  • Previous evidence of hypersensitivity or an allergic reaction to atomoxetine
  • Clinically significant abnormalities in laboratory measures indicating an undiagnosed medical condition as determined by the study physician in discussion with the participant's primary care physician
  • Clinically significant abnormalities on ECG as determined by a pediatric cardiologist
  • Pregnant
  • Initiation of a new psychosocial intervention within 90 days prior to starting study medication. Participants who have recently had a significant change in their psychosocial interventions will not be eligible until this intervention has been stable for 90 days in order to avoid confounding results of the study. Stable interventions (e.g., speech and occupational therapy) will be allowed to continue during the course of the study. Minor changes in ongoing treatment (e.g., missed therapy sessions due to holiday/vacation planned break in therapy due to school holidays) will not be considered significant
