Fesoterodine is used to treat overactive bladder (bladder function disorder that causes a sudden or frequent urge to urinate).
This medicine calms and relaxes the bladder. It reduces the number of toilet visits and the urge to urinate.
Take Fesoterodine exactly as directed by your doctor or according to the instructions on the label. Do not take more or less than instructed by your doctor.
You may take this medicine with or without food. Try to take it at the same time each day.
If you are taking the extended-release or prolonged-release type of tablet (usually labeled as "XL" or “ER”), swallow it whole. Do not divide, chew or crush the tablet.
The dose of Fesoterodine will be decided by your doctor. Your doctor will advise you on the treatment timeframe depending on the type and severity of your condition.
Take the missed dose as soon as you remember. If it is almost time for your next dose, skip the missed dose and return to your normal dosing schedule.
