" Urinary Incontinence "

Excerpt:

Pharmacologic causes

Many medications directly or indirectly contribute to urinary

incontinence. They must always be considered as the cause of new-onset

urinary incontinence, especially in elderly persons where polypharmacy

is often encountered.13,14

•Medications with anticholinergic properties or side effects including

antipsychotics and antidepressants can cause urinary retention and

thus overflow incontinence.

•Alpha-adrenergic agonists can cause urinary retention and thus

overflow urinary incontinence.

•Alpha-antagonist cause urethral relaxation and thus urinary incontinence.

•Diuretics can overwhelm bladder capacity causing urinary incontinence

in elderly persons.

•Calcium channel blockers decrease smooth muscle contractility in the

bladder causing urinary retention with overflow incontinence.

•Sedative-hypnotics can cause functional urinary incontinence by

causing immobility secondary to sedation.

•ACE inhibitors can exacerbate urinary incontinence by effects of

diuresis as well as side effect of cough with relaxation of pelvic

floor musculature.

•Anti-parkinson medications can cause urinary urgency and constipation.
