Flavoxate (FX)

Flavoxate is indicated for symptomatic relief of interstitial cystitis, dysuria, urgency, nocturia, suprapubic pain, frequency and incontinence as may occur in cystitis, prostatitis, urethritis, urethrocystitis/urethrotrigonitis.

Flavoxate is generally well tolerated, but can potentially cause, vomiting, upset stomach, dry mouth or throat, blurred vision, eye pain, and increased sensitivity of your eyes to light. Flavoxate is contraindicated in patients who have any of the following obstructive conditions: pyloric or duodenal obstruction, obstructive intestinal lesions or ileus, achalasia, gastrointestinal hemorrhage and obstructive uropathies of the lower urinary tract.
