Effectiveness
How Hiprex Affects Patients
Taking 1 gram of methenamine hippurate produces an antibacterial effect in the urine after half an hour. Taking 1 gram of this drug twice a day will keep your urine antibacterial for a longer period of time.
How Hiprex works in the body
Methenamine is a drug that works by turning into formaldehyde when in an acidic environment. Formaldehyde is a highly effective bacteria-killer, as it damages proteins and genetic material. Some bacteria can create an alkaline environment, which stops the formaldehyde from working. The salt component of the drug helps keep the environment acidic, so the formaldehyde can do its job.
