User Reviews for Fleet Phospho Soda

Fleet Phospho Soda (sodium biphosphate / sodium phosphate) for Constipation: Very strong but gentle. Box says wait 30 min to 6 hours. Found from personal experience that you don't take this unless you plan on staying home. It always took 2 hours to work for me so once I took it and then ran some errands, expecting to be home in 45 minutes-plenty of time of course (since it was the only time I ever took it and left home) it started working in 30 minutes as the box said. Once you feel a "gurgling" feeling in your intestines you better get to a bathroom. Fortunately I was close to home but barely made it home since my insides had turned to water. Once it starts working I have a few watery movements over 2 hours then all is well. No cramping, tastes better if diluted with lots of cold water. Drink it as fast as you can.

Fleet Phospho Soda (sodium biphosphate / sodium phosphate): This site provided information not on the bottle. For example, taking it with 4 oz. of water. It was yukky to drink straight.
