Methenamine Hippurate
INFORMATION ABOUT METHENAMINE HIPPURATE
Methenamine Hippurate Uses
Methenamine Hippurate is used in the treatment of urinary tract infections (UTIs).
How Methenamine Hippurate works
Methenamine Hippurate helps prevent urinary tract infections by converting into formaldehyde, a substance that kills bacteria, when the urine is sufficiently acidic. The hippurate component helps maintain the acidic environment needed for this conversion. This targeted action in the urinary tract reduces the risk of developing resistance and is effective in preventing recurring infections.
