NICE Clinical Guideline NG123 (2019): Urinary incontinence and pelvic organ prolapse in women: management
|Before initiating treatment a thorough investigation of the underlying cause of incontinence should be carried out and drug treatments should be reviewed 4 weeks after starting. If there is no or suboptimal improvement or intolerable adverse effects change the dose, or try an alternative antimuscarinic drug, and review again 4 weeks later.
Thereafter, treatments should be reviewed annually, or every 6 months if patient is over 75 years.
Pelvic floor muscle training. NICE recommends a trial of supervised pelvic floor muscle training of at least 3 months' duration as first-line treatment to women with stress or mixed UI, comprising at least 8 contractions performed 3 times per day.

|Research has shown that concordance after 3 years is less than 10% regardless of class of drug use with little to differentiate treatment options (Shamliyan T, et al. Benefits and harms of pharmacologic treatment for urinary incontinence in women. A systemic review. Ann Intern Med 2012; 156:861-74)
NICE advises that some adverse effects are indications that treatment is having effect and that they may not see full benefits for 4 weeks.
If first treatment for OAB or mixed UI is not effective or not tolerated, offer another drug with the lowest acquisition cost.
Aim to avoid additional antimuscarinic drugs particularly in elderly and patients with dementia due to risk of delirium. See muscarinic load below.
As per NICE guideline [NG123] April 2019 -
When offering anticholinergic medicines to treat overactive bladder, take account of the woman's:
•coexisting conditions (such as poor bladder emptying, cognitive impairment or dementia)
•current use of other medicines that affect total anticholinergic load
•risk of adverse effects, including cognitive impairment
For women who have a diagnosis of dementia and for whom anticholinergic medicines are an option, follow the recommendations on medicines that may cause cognitive impairment in the NICE guideline on dementia.
