Oxybutynin is used to treat urination problems such as passing urine too frequently, leaking urine, an inability to control or "hold" urination or an urgent need to pass urine. Urination problems such as these are often due to an overactive bladder. Oxybutynin helps to reduce the number of toilet visits and the urge to urinate. It also helps the bladder to hold urine better.
