"April 29, 2015 -- If you've ever had one (or a dozen) urinary tract infections, you might not be surprised to learn that they're the most common bacterial infections in the United States.
What you might not know is that doctors are running "...
The components of this product, trimethoprim/sulfamethoxazole/phenazopyridine hydrochloride, are indicated in the treatment of urinary tract infections as follows:
Trimethoprim/Sulfamethoxazole is indicated for the treatment of urinary tract infections due to susceptible strains of the following organisms: Escherichia coli, Klebsiella species, Enterobacter species, Morganella morganii, Proteus mirabilis and Proteus vulgaris.
Phenazopyridine Hydrochloride is indicated for the symptomatic relief of pain, burning, urgency, frequency, and other discomforts arising from irritation of the lower urinary tract mucosa caused by infection. The use of phenazopyridine hydrochloride for relief of symptoms should not delay definitive diagnosis and treatment of causative conditions. Because it provides only symptomatic relief, prompt appropriate treatment of the cause of pain must be instituted and phenazopyridine hydrochloride should be discontinued when symptoms are controlled.
Phenazopyridine is compatible with antibacterial therapy and can help to relieve pain and discomfort during the interval before antibacterial therapy controls the infection. Treatment of a urinary tract infection with phenazopyridine hydrochloride should not exceed 2 days. (See DOSAGE AND ADMINISTRATION section.)
