Abstract
BACKGROUND Clozapine is the most effective medication for treatment-refractory schizophrenia but is associated with significant adverse drug reactions, including nocturnal enuresis and urinary incontinence. This side effect can be burdensome and lead to medication nonadherence and psychotic relapse. Evidence to guide treatment of clozapine-induced nocturnal enuresis and urinary incontinence is sparse. We therefore aimed to synthesize the evidence base to guide management for clinicians, patients, and their carers. METHODS We systematically searched PubMed, Embase, PsycInfo, CINAHL, and the Cochrane Trial Registry databases from inception to May 2021 for publications on management of clozapine-induced nocturnal enuresis and urinary incontinence using a PROSPERO preregistered search strategy. RESULTS We identified 22 case reports and case series describing 74 patients. Interventions included clozapine dose reduction, nonpharmacological treatment, and pharmacological treatments. Among pharmacological treatments, desmopressin, oxybutynin, trihexyphenidyl, tolterodine, imipramine, amitriptyline, ephedrine, pseudoephedrine, aripiprazole, and verapamil were associated with complete resolution of nocturnal enuresis and urinary incontinence. Balancing evidence for effectiveness against risk of adverse effects, we developed a management framework for clozapine-induced nocturnal enuresis and urinary incontinence. CONCLUSIONS Following assessment of urological, psychiatric, pharmacological, and common comorbid medical issues, first-line treatments should be nonpharmacological, including bathroom alarms, voiding before bedtime, and nocturnal fluid restriction. If these interventions do not provide adequate relief, aripiprazole should be trialed. Desmopressin may be considered for severe refractory cases, but monitoring for hyponatremia is essential.

Abstract
To date, due to the increasing prevalence of psychiatric diseases, the use of antipsychotic drugs has expanded. One of the proven side effects of these drugs is incontinence. Treatment of this complication improves the quality of life in these patients, increases self-confidence, and betters cope with their psychiatric illness. The exact mechanism of this side effect is not fully understood, but various methods have been used experimentally to deal with it. Strategies such as behavior therapy, discontinuation or change of drugs, reducing the dose of drugs, and adding drugs with less incontinence have been used. Each of these methods and studies has different results that need to be summarized to make optimal use of them. Since most of these reports are case reports with a low statistical population, our study has systematically reviewed these studies to find a comprehensive model to deal with this complication.
