Flavoxate 200 mg is a bladder-muscle relaxant used for relief of urinary symptoms such as:
- Urgency and frequent urination
- Painful urination
- Night-time urination
- Bladder spasms or urge incontinence
It may be used when symptoms occur with cystitis, prostatitis, or urethritis, but it is
not an antibiotic and does not treat a urinary infection itself.
