Methenamine
"Hiprex is amazing! I suffered for years with chronic UTI's and was constantly on antibiotics which made me feel even worse. I tried everything from ural sachets to cranberry tablets and nothing helped until I tried hiprex. As long as you take the recommended 2 tablets each day (one in morning, one at night) it works! The only downside is the taste of the tablets but I found taking it with some food helps mask the taste."
