Urispas (flavoxate HCl) is a synthetic urinary tract spasmolytic used to treat bladder symptoms such as frequent or urgent urination, increased nighttime 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 is not an antibiotic, and does not cure infections. Urispas is available in generic form. Common side effects of Urispas include:

  • nausea,
  • vomiting,
  • dry mouth,
  • headache,
  • drowsiness,
  • dizziness,
  • spinning sensation,
  • blurred vision,
  • nervousness, and
  • fever.
