Researchers in Barcelona, Spain retrospectively reviewed the use of antipsychotics in 117,811 patients, of whom 9,855 were given combinations of antipsychotics and 13,763 were given unspecified combinations of drugs. The researchers found that “the scant evidence available regarding the efficacy of combining different antipsychotics contrasts with the high number and variety of combinations prescribed to outpatients.” The study appears in BMC Psychiatry.
