Before Using fesoterodine
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For fesoterodine, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to fesoterodine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals.
