Hiprex (methenamine hippurate) 


Hiprex is used for conditions like- 

  • Urinary Tract Infections (UTIs): Used to prevent and treat urinary tract infections by stopping the growth of bacteria in the urine. 
  • Chronic UTIs: Helps in the long-term prevention of recurrent urinary tract infections. 

Dosage and Administration 

  • Take Hiprex tablets with a full glass of water to help ensure proper absorption and effectiveness. 
  • Swallow the tablets whole; do not crush, chew, or break them. 
  • Adhere strictly to the prescribed dosage and timing as advised by your doctor. 
  • Take the medication at the same times each day to maintain an even level in your bloodstream. 
  • Maintain an acidic diet (e.g., cranberry juice, vitamin C supplements) to enhance the effectiveness of Hiprex. 
  • Avoid missing doses; if you miss a dose, take it as soon as you remember unless it is almost time for the next dose. 
  • Do not take two doses at the same time to make up for a missed dose. 
  • Do not take antacids containing sodium bicarbonate or other alkaline substances as they can reduce the effectiveness of Hiprex. 

Mechanism of Action 

Hiprex works by being converted to formaldehyde in acidic urine, which is toxic to bacteria. This action helps to prevent the growth of bacteria in the urinary tract, reducing the risk of infections.
