1. What Oxybutynin hydrochloride is and what it is used for
Oxybutynin hydrochloride belongs to two groups of medicines called “antispasmodics” and “anticholinergics”.
Oxybutynin hydrochloride works by helping to reduce the muscle spasms of the bladder. It is these spasms which make you feel that you need to urinate often. Oxybutynin therefore has the effect of relaxing the bladder muscle so the bladder can hold more urine and the frequent urge to urinate is reduced. Oxybutynin hydrochloride Tablets may therefore be used to treat conditions whereby you are unable to control your bladder normally. The reason for this happening may not be known or may be due to a disorder affecting the body's nerves to the bladder.
Oxybutynin hydrochloride can be used in adults and children 5 years or older to treat:
- Loss of control in passing urine (urinary incontinence)
- Increased need or urgency to pass urine
- Night time bedwetting, when other treatments have not worked
2. What you need to know before you take Oxybutynin hydrochloride Do not take Oxybutynin hydrochloride:
- if you are allergic to oxybutynin or any of the other ingredients of this medicine (listed in section 6)
- if you have difficulty passing urine
- if you suffer from a severe condition called ulcerative colitis, or have noticed blood and mucus in your
stools
- if you suffer from a sluggish bowel, are constipated or have a gut problem (your gut is blocked,
perforated or not working properly)
- if you suffer from a condition which causes weak muscles (Myasthenia gravis)
- if you suffer from glaucoma (raised pressure in the eye)
- if you have a heart condition causing a racing or irregular heart beat
- if you have been told that you have a condition where the tissue of the brain is hardening (cerebral
sclerosis)
