Flavoxate

Flavoxate is used to treat overactive bladder (a condition in which the bladder muscles contract uncontrollably and cause frequent urination, urgent need to urinate, and inability to control urination) relieve painful, frequent, or nighttime urination and urgency that may occur with infections of the prostate, bladder, or kidneys. Flavoxate is in a class of medications called antimuscarinics. It works by relaxing the bladder muscles. However, flavoxate is not an antibiotic; it does not cure infections.
