Different medicines may do this in different ways and sometimes it's a combination of medicines that can make the problem worse. This is more likely for older people or those who are taking a lot of medicines.
For example, medicines may:
- Increase urine production (eg, diuretics – also called water pills).
- Relax the the bladder which leads to urinary retention, or difficulty in starting to pee or straining while peeing.
- Relax the muscle at the outlet of the bladder which may cause leaking when coughing, sneezing or laughing.
- Relax the urethra leading to frequent peeing.
- Cause coughing which can cause stress incontinence.
