What is oxybutynin?
Oxybutynin reduces muscle spasms of the bladder and urinary tract.
Oxybutynin is used to treat symptoms of overactive bladder, such as frequent or urgent urination, incontinence (urine leakage), and increased night-time urination.
Oxybutynin is also used in children at least 6 years old with overactive bladder related to a neurologic condition such as spina bifida.
You should not use oxybutynin if you have untreated or uncontrolled narrow-angle glaucoma, a blockage in your digestive tract (stomach or intestines), or if you are unable to urinate.
Before using oxybutynin, tell your doctor if you have glaucoma, liver or kidney disease, an enlarged prostate, myasthenia gravis, ulcerative colitis, a blockage in your stomach or intestines, or a stomach disorder such as gastroesophageal reflux disease (GERD) or slow digestion.
Avoid becoming overheated or dehydrated during exercise and in hot weather. Oxybutynin can decrease perspiration and you may be more prone to heat stroke.
