Flavoxate

Flavoxate reduces muscle spasms in the bladder and urinary tract.

Flavoxate is used to treat bladder symptoms like painful urination, frequent or urgent urination, needing to urinate more at night, 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.

Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended.

Your doctor may occasionally change your flavoxate dose to make sure you get the best results.

Call your doctor if your symptoms do not improve, or if they get worse.

If your doctor has also prescribed medicine to treat a bladder infection, use that medicine for the full prescribed length of time. Your symptoms may improve before the infection is completely cleared. Skipping doses may also increase your risk of further infection that is resistant to antibiotics.

Store flavoxate at room temperature away from moisture, heat, and light.

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.

You should not use flavoxate if you are allergic to it, or if you have:

• blockage in your digestive tract (stomach or intestines);
• 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:

• glaucoma; or
• urination problems.
