Urispas reduces muscle spasms of the bladder and urinary tract.

Urispas 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.

Urispas will not treat a bladder infection. Infections must be treated with an antibiotic.

Urispas may also be used for purposes not listed in this medication guide.

You should not use Urispas if you have bleeding or a blockage in your digestive tract (stomach or intestines), a bladder obstruction, or if you are unable to urinate.

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 Urispas 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 Urispas at room temperature away from moisture, heat, and light.

You should not use Urispas 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 Urispas is safe for you, tell your doctor if you have:

• glaucoma; or

• urination problems.
