    Abstract

    OBJECTIVE: To report the use and subsequent failure of the bladder-selective agent tolterodine, to treat clozapine-induced nocturnal enuresis in an adolescent patient with psychotic illness. CASE SUMMARY: A 16-year-old Hispanic girl was admitted to the state psychiatric hospital with a diagnosis of bipolar disorder with psychotic features. Clozapine therapy was initiated, and after three months of treatment the patient began experiencing episodes of nocturnal enuresis. The bladder-selective agent tolterodine was tried and subsequently failed to resolve the enuresis episodes. Desmopressin was initiated, which resulted in amelioration of symptoms. DISCUSSION: This is the first published report of using tolterodine to treat clozapine-induced nocturnal enuresis. Several methods to decrease clozapine-induced urinary incontinence have been used and typically include the addition of agents with high anticholinergic properties. Tolterodine is a bladder-selective anticholinergic agent indicated for the treatment of urinary urge incontinence and may be employed as a treatment for antipsychotic-induced incontinence. CONCLUSIONS: Nocturnal enuresis is an adverse effect that infrequently occurs with use of clozapine therapy. Although tolterodine was ineffective in our patient to treat clozapine-induced nocturnal enuresis, further trials are required to appropriately evaluate the effectiveness of tolterodine to treat this adverse drug reaction.
