Flavoxate is a urinary antispasmodic (also known as an anticholinergic).

Pronunciation: flay-vox-ate

What are flavoxate’s uses?

Flavoxate is used to treat muscle spasms in the bladder and urinary tract, as it relaxes the smooth muscles in the bladder.

It is taken in tablet form, and is usually prescribed to relieve difficult urination (for example, an overactive bladder where the bladder muscles contract uncontrollably causing frequent urination), as well as side effects of conditions such as prostate, bladder or kidney infection that affect urination.

What dosage should you take?

The typical dose for adults is 200mg three times daily.

Flavoxate is generally not recommended for usage by children younger than 12. However, consult with your doctor and Clicks pharmacist first.
