In this session, we will be discussing the consumer medication information for darifenacin, trade name EnablexTM.

What it’s for & How to take

Darifenacin is used to treat the symptoms of overactive bladder. This medication helps relax the muscles in the bladder, so they do not squeeze too quickly.

Darifenacin will help relax the bladder so that it may fill to a normal level before you feel the urge to urinate. Relaxing the bladder muscles will decrease the feeling that you need to frequently urinate and may decrease bladder leakage.

Darifenacin is usually taken once daily, with or without food, or as directed by your doctor. Swallow this tablet whole, with a full glass of water. Take this medication at the same time each day.

If you forget to take a dose, take it as soon as you remember. If it is near the time of your next dose, skip it and continue with your normal dose time. Do not take a double dose to make up the missed dose.

Your dosage is based on your condition and response to therapy. Your doctor may have you stop the medication for a period of time to see if you need to continue taking it. If the feeling of frequent urination does not improve or gets worse, notify your doctor.
