What is Urispas?

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.
