About This Medication
What the Medication is Used For

- known hypersensitivity to tolterodine L-tartrate or any of the other ingredients in DETROL LA.

Warnings and Precautions
DETROL LA may have an effect on the electrical activity of the heart. This effect can be measured as a change in the electrocardiogram (ECG). It is important to follow the instructions of your doctor with regard to dosing or any special tests. In very rare cases, drugs with an effect on the ECG can lead to disturbances in heart rhythm (arrhythmias/dysrhythmias). These heart rhythm disturbances are more likely in patients with risk factors, such as heart disease, or in the presence of certain interacting drugs. If you experience any symptoms of a possible heart rhythm disturbance, such as dizziness, palpitations (sensation of rapid pounding, or irregular heart beat), fainting, or seizures, you should stop taking DETROL LA and seek immediate medical attention.

- you are pregnant, or trying to become pregnant
- you are breastfeeding your child

- you have stomach problems affecting passage and digestion of food
- you have liver problems
- you have kidney problems
- you are taking medication bought without a prescription. They may affect your condition, or how DETROL LA works for you.
- you are a female or are over 65 years in age; you have a disorder known as Long QT Syndrome; a heart disease; a history of stroke or brain hemorrhage; a personal history of fainting spells; a family history of sudden cardiac death at <50 years; electrolyte disturbances (e.g., low blood potassium levels); an eating disorder or are following an extreme diet; diabetes, especially with associated nerve disorders
