Hiprex 20 Tablets

Information 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. Hiprex is an antibiotic that stops the growth of bacteria in urine. Hiprex also contains an ingredient that helps to make the urine acidic. When the urine is acidic, Hiprex turns into formaldehyde to kill the bacteria.Warnings 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.
