new concerns about the safety of sodium phosphate bowel preps

There are new concerns about the safety of sodium phosphate bowel preps...Fleet Phospho-soda and Phosphates Solution.

Oral sodium phosphate is better tolerated than PEG solutions (GoLytely, etc). It can also be more effective...especially since patients are more likely to finish oral sodium phosphate regimens.

The problem is that sodium phosphate can cause electrolyte changes and dehydration. This can lead to acute renal failure if calcium and phosphate crystals precipitate in the kidney.
