Diabetic ketoacidosis associated with aripiprazole.

Metabolic adverse effects such as hyperglycemia, alterations in insulin sensitivity, and weight gain are known to be potential complications of atypical antipsychotic therapy. In certain cases, hyperglycemia may be so profound that diabetic ketoacidosis (DKA) or hyperosmolar coma may result. Aripiprazole, approved by the United States Food and Drug Administration in 2002, appears to have fewer metabolic adverse effects than other atypical antipsychotics.
