IMPORTANT SAFETY INFORMATION

Hiprex® (methenamine hippurate tablets USP)

WHAT IS HIPREX USED FOR?

Hiprex® (methenamine hippurate tablets USP) are used to prevent or control recurring urinary tract infections caused by certain bacteria.  Hiprex is not used to treat an active infection; Hiprex should only be used after the infection has been treated with other antibiotics.

WHEN SHOULD I NOT TAKE THE DRUG?

You should not take Hiprex if you are allergic to methenamine hippurate, formaldehyde, or any of the other ingredients in the drug, or if you are taking a sulfonamide drug.

You should not take Hiprex unless your doctor has confirmed that your infection is caused by bacteria that is susceptible to Hiprex.  Hiprex is effective only against bacterial infections in the urinary tract.  It will not work for other types of bacterial infections or for viral infections (such as the common cold or flu).  Unnecessary use of Hiprex can lead to its decreased effectiveness and the development of antibiotic-resistant bacteria.

You should not take Hiprex if you have kidney failure, severe liver insufficiency, or you are severely dehydrated.

WHAT WARNINGS SHOULD I KNOW ABOUT HIPREX?

Large doses of Hiprex (8 pills/day for 3-4 weeks) can cause bladder irritation, painful and frequent urination, cause protein to leak into the urine, and cause blood in the urine.

You should also be aware that taking Hiprex before a bacterial infection has been confirmed increases the risk of developing drug resistant bacteria.

When taking Hiprex:

Hiprex should only be used to treat bacterial infections.  Hiprex will not treat a viral infection (such as the common cold)

WHAT SHOULD I TELL MY HEALTHCARE PROVIDER?
