How does this medication work? What will it do for me?
Tolterodine belongs to a group of medications known as antispasmodics and anticholinergics. It is used to treat people with overactive bladders who have symptoms including frequent urination, urgency, or involuntary loss of urine. Tolterodine helps these symptoms by preventing contractions or spasms of the bladder.
Relief from symptoms may not be seen until about 2 weeks after starting treatment with tolterodine, and more improvement is seen after 8 weeks.
