Aripiprazole, sold under the brand name Abilify among others, is an atypical antipsychotic. It is recommended and primarily used in the treatment of schizophrenia and bipolar disorder. Other uses include as an add-on treatment in major depressive disorder, tic disorders, and irritability associated with autism. According to a Cochrane review, evidence for the oral form in schizophrenia is not sufficient to determine effects on general functioning. Additionally, because many people dropped out of the medication trials before they were completed, the overall strength of the conclusions is low.
Side effects include neuroleptic malignant syndrome, a movement disorder known as tardive dyskinesia, and high blood sugar in those with diabetes. In the elderly there is an increased risk of death. It is thus not recommended for use in those with psychosis due to dementia. It is pregnancy category C in the United States and category C in Australia, meaning there is possible evidence of harm to the fetus. It is not recommended for women who are breastfeeding. It is unclear whether it is safe or effective in people less than 18 years old.
