Routine management of constipation is a critical part of clozapine treatment. There are case reports of fatal ileus related to clozapine therapy.
-The first step is to minimize the use of systemic anticholinergics.
-Docusate should be used routinely. Bulk agents can make constipation worse and should be avoided.
-After docusate, the next agent to add is PEG 3350.
-Lubiprostone, a more expensive agent, can also be tried. It can be used if the combination of docusate + PEG-3350 + a stimulant is not effective.
Up to 30% of patients with treatment-resistant schizophrenia treated with clozapine have residual positive symptoms. Clozapine augmentation is a common approach, but the evidence supporting this practice is limited.
According to the latest evidence, risperidone, lamotrigine, topiramate, or ECT are potential augmenting options.
David N. Osser, MD Associate Professor of Psychiatry Harvard Medical School Brockton Division of the VA Boston Healthcare System First-generation LAIs (haloperidol, fluphenazine) have higher rates of acute extrapyramidal symptoms, tardive dyskinesia and hyperprolactinemia symptoms compared to most second-generation antipsychotics.
