How It Works
Anticholinergic medications block nerves that control bladder
muscle contractions and allow for relaxation of the bladder smooth muscle.
These actions work together to help control
urinary incontinence.
Why It Is Used
Anticholinergic medications are used to treat urge incontinence,
also called overactive bladder.
How Well It Works
A recent study showed an 85% reduction in urge incontinence using
anticholinergic medication and behavioural techniques, compared with 72% and 57%
reduction after using only anticholinergic medications or behavioural
techniques. In other words, using anticholinergic medication and behavioural
techniques together reduces urge incontinence better than either treatment used
alone.1
Side Effects
Side effects are common and include:
- Dry mouth, nose, and throat.
-
Dizziness, drowsiness, and confusion.
- Decreased sweating and skin
rash.
- Nausea and constipation.
- Eye pain.
-
Rapid heartbeat.
Extended-release formulas and the Oxytrol skin patch may have fewer
side effects than anticholinergic medications that are taken several times a
day.
See Drug Reference for a full list of side effects. (Drug
Reference is not available in all systems.)
What To Think About
These medications may reduce the amount you sweat, which in hot
weather could lead to heat exhaustion. Be careful about being physically active
in hot conditions.
Avoid alcoholic beverages while taking anticholinergic medications,
because they can increase the depressive effects of alcohol. Anticholinergic
medications may cause drowsiness or blurred vision that could interfere with
your ability to drive or to operate machinery. They may cause your eyes to
become more sensitive to light. If this occurs, wear sunglasses to reduce eye
discomfort. If you develop diarrhea while taking an anticholinergic medication,
stop taking it and call your doctor. You may need to be checked for partial
intestinal blockage.
Before taking medications for urinary incontinence, talk to your
health professional about the following:
- Can your incontinence be
treated with behavioural or exercise therapy before trying medications?
Behavioural or exercise therapy, such as bladder training or pelvic floor
(Kegel) exercises, is non-invasive, can be done at home, is inexpensive, has no
side effects, and does not limit future therapy options if it is not
successful.
- How much experience does your health
professional have in treating incontinence? Some health professionals do
not realize the impact that urinary incontinence can have on a person's life
and may disregard your concerns.
- Could any of the
medications you are taking for another condition be causing your
incontinence? Some medications cause the body to produce greater amounts
of urine, which may contribute to incontinence problems. Take water pills or
diuretics when you will easily be able to get to a bathroom.
