Side effects are generally similar to other antipsychotics. The drug has a relatively well-tolerated side effect profile, with low propensity for QTc interval changes, weight gain and lipid-related adverse effects.[24] In a 2013 meta-analysis of the efficacy and tolerability of 15 antipsychotic drugs it was found to produce the second least (after haloperidol) weight gain, the least QT interval prolongation, the fourth most extrapyramidal side effects (after haloperidol, zotepine and chlorpromazine) and the sixth least sedation (after paliperidone, sertindole, amisulpride, iloperidone and aripiprazole).[2]
