Summary
Darifenacin is used to treat overactive bladder symptoms, which include frequent urination, urgency, and incontinence, which is the inability to control urination.
Darifenacin works by blocking certain receptors in the bladder, which helps relax the bladder muscles. This action reduces the urgency and frequency of urination.
The usual starting dose of Darifenacin for adults is 7.5 mg once daily. Your doctor may increase the dose to 15 mg daily if needed. It's taken orally, which means by mouth.
Common side effects of Darifenacin include dry mouth, constipation, and blurred vision. These effects are usually mild and occur in a small percentage of people.
Do not take Darifenacin if you have urinary retention, which is the inability to empty your bladder, or uncontrolled narrow-angle glaucoma, which is increased pressure in the eye. It can also cause heat prostration, which is overheating due to decreased sweating.
