Management of Urinary Retention in Patients Requiring Multiple Anticholinergic Medications

Assessment and Prioritization

The American Academy of Child and Adolescent Psychiatry recommends discontinuing or reducing the anticholinergic medication used for managing side effects of other drugs, while maintaining those essential for treating the underlying disorders, when a patient develops urinary retention while on multiple anticholinergic medications 1
Determine which anticholinergic medications are treating primary conditions versus those managing side effects of other medications, to prioritize medication adjustment 1

Consider gradual tapering of anticholinergic medications rather than abrupt discontinuation to avoid withdrawal symptoms or rebound worsening of symptoms 1
For patients with overactive bladder requiring anticholinergic therapy, consider switching to a beta-3 adrenergic receptor agonist which has less risk of urinary retention 2

Monitor post-void residual urine volume to assess for improvement after medication adjustments, as recommended by The Journal of Urology 3
Exclude or treat constipation, which can exacerbate urinary retention and is a common side effect of anticholinergic medications, according to The Journal of Urology 3

Patients with neurogenic lower urinary tract dysfunction may require specialized management approaches, including possible intermittent catheterization, as suggested by Praxis Medical Insights 2

Regularly assess the continued need for anticholinergic medications through periodic drug holidays, as recommended by The Journal of Urology 3
Evaluate bladder function periodically, especially in patients with chronic indwelling catheters or those requiring intermittent catheterization, according to Praxis Medical Insights 2
