Tolterodine is used to treat overactive bladder (a condition in which the bladder muscles contract uncontrollably and cause frequent urination, urgent need to urinate, and inability to control urination). Tolterodine is in a class of medications called antimuscarinics. It works by relaxing the bladder muscles preventing bladder contraction.

Tolterodine comes as a tablet and an extended-release (long-acting) capsule to take by mouth. The tablet is usually taken twice a day. The extended-release capsule is usually taken once a day with liquids. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take tolterodine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Swallow the extended-release capsules whole; do not split, chew, or crush them.
Keep all appointments with your doctor.
Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.
It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
