2. What is your medicine used for?
Oxybutynin belongs to a group of medicines called antispasmodics, which help relax spasms in
certain types of smooth muscle.
Oxybutynin also belongs to another group of medicines called anticholinergics, which reduce the
effect of acetylcholine, a substance involved transmitting signals between nerves.
You have been prescribed Oxybutynin 5 mg Tablets to treat one of the following bladder problems:
• Difficulty controlling when to pass water (urinary incontinence)
• Needing to pass water very suddenly (urinary urgency)
• Needing to pass water very often (urinary frequency)
These problems can be caused either by spasms of the smooth muscles that control the bladder, or
by signals sent by the nerves in the spine that control these muscles, caused by conditions such as
multiple sclerosis or spina bifida. Oxybutynin 5 mg Tablets can treat both these causes and help
reduce the feeling of urgency and the number of times you need to urinate.
