Urispas (flavoxate HCl) is a synthetic urinary tract spasmolytic used to treat bladder symptoms such as 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. It 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.
The dose of Urispas for adults and children over 12 years of age is one or two 100 mg tablets 3 or 4 times a day. This drug is not recommended for children under 12 years of age. Urispas may interact with other bladder or urinary medications such as darifenacin, oxybutynin, tolterodine, or solifenacin.
