Flavoxate is used to relieve painful, frequent, or nighttime urination and urgency that may occur with infections of the prostate, bladder, or kidneys. The drug works by relaxing the muscles involved with urination. However, flavoxate is not an antibiotic; it does not cure infections.
This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.
Flavoxate comes as a tablet. Flavoxate usually is taken three or four times a day. This drug may be taken with or without food. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take flavoxate exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.
