Tolterodine is used to treat a condition called overactive bladder. Overactive bladder happens when you cannot control your bladder muscle. When the muscle contracts too often or cannot be controlled, you get symptoms of overactive bladder such as:
- not being able to control when to empty your bladder, where you get a strong need to urinate with leaking or wetting incidence (urinary incontinence)
- a strong need to urinate right away (urgency)
- urinating often (frequency)
