Oxybutynin is used in the treatment of overactive bladder (OAB) symptoms. OAB is characterized by a range of urinary symptoms, including frequent urination, an urgent need to urinate, and an inability to control urination.
How Oxybutynin Works Oxybutynin is an antimuscarinic medication. It functions by relaxing the muscles of the urinary bladder, thereby preventing frequent, urgent, or uncontrolled urination.
