What is the most important information I should know about flavoxate?
You should not use flavoxate if you have bleeding or a blockage in your digestive tract (stomach or intestines), a bladder obstruction, or if you are unable to urinate.
What is flavoxate?
Flavoxate reduces muscle spasms of the bladder and urinary tract.
Flavoxate is used to treat bladder symptoms such as painful urination, frequent or urgent urination, increased night-time urination, bladder pain, and incontinence (urine leakage). These bladder symptoms are often caused by overactive bladder, prostate enlargement, bladder infections, or irritation of the urethra.
Flavoxate will not treat a bladder infection. Infections must be treated with an antibiotic.
Flavoxate may also be used for purposes not listed in this medication guide.
What should I discuss with my health care provider before taking flavoxate?
You should not use flavoxate if you are allergic to it, or if you have:

- stomach or intestinal bleeding; or
- bladder obstruction or if you are unable to urinate.
To make sure flavoxate is safe for you, tell your doctor if you have:
