Fesoterodine Fumarate Information

Fesoterodine (fes oh ter' oh deen) Toviaz®

Fesoterodine 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). Fesoterodine is in a class of medications called antimuscarinics. It works by relaxing the bladder muscles to prevent urgent, frequent, or uncontrolled urination.

Fesoterodine comes as an extended release (long-acting) tablet to take by mouth. It is usually taken with or without food, once a day. Take fesoterodine at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take fesoterodine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor. Swallow the tablets whole with plenty of liquid; do not split, chew, or crush them. Your doctor may start you on a low dose of fesoterodine and increase your dose if your symptoms are not controlled. Talk to your doctor about how fesoterodine works for you Your symptoms should begin to improve during the first few weeks of your treatment with fesoterodine.

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom). Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website ( for more information if you do not have access to a take-back program. It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach.

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.

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.
