Citalopram (Celexa) has limited efficacy in the management of repetitive behaviors in children and adolescents with ASDs, and is more likely to be associated with side effects. It may be beneficial in the treatment of other associated symptoms. *There are currently no published studies of citalopram in adults with ASDs.
Citalopram may have favorable responses for a range of symptoms, including repetitive behaviors and preoccupations, aggression, anxiety, and disturbed mood.
Dosages range from 5 to 40 mg/day.
Side events may include increased energy, impulsiveness, decreased concentration, hyperactivity, stereotypy, diarrhea, insomnia, or dry or itchy skin (“pruritic”).
