Tolterodine

Tolterodine is used 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.

This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

Before taking tolterodine,

• tell your doctor and pharmacist if you are allergic to tolterodine, fesoterodine fumarate (Toviaz), any other medications, or any of the ingredients in tolterodine tablets or extended-release capsules. Ask your pharmacist for a list of the ingredients.
• tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking or plan to take while taking tolterodine. Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
• tell your doctor if you have or have ever had glaucoma (increased pressure in the eye that may cause vision loss), urinary retention (inability to empty your bladder completely or at all), or gastric retention (slow emptying of your stomach).Your doctor may tell you not to take tolterodine.
• tell your doctor if you or anyone in your family has or has ever had a prolonged QT interval (a rare heart problem that may cause irregular heartbeat, fainting, or sudden death), or if you have or have ever had bladder problems, stomach or bowel problems including problems with constipation, myasthenia gravis (a disorder of the nervous system that causes muscle weakness), or kidney or liver disease..
• tell your doctor if you are pregnant, plan to become pregnant, or are breastfeeding. If you become pregnant while taking tolterodine, call your doctor.
• you should know that tolterodine may make you dizzy or drowsy, or cause blurred vision or other vision problems. Do not drive a car or operate machinery until you know how this medication affects you.

Take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.

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 light, excess heat and moisture (not in the bathroom).

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. https://www.upandaway.org

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 (https://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

In case of overdose, call the poison control helpline at 1-800-222-1222. Information is also available online at https://www.poisonhelp.org/help. If the victim has collapsed, had a seizure, has trouble breathing, or can't be awakened, immediately call emergency services at 911.

Symptoms of overdose may include the following:

• confusion
• dry mouth

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.
