FDA Issues Safety Warning for Sodium Phosphate for Constipation

The US Food and Drug Administration (FDA) is warning about possible harm from exceeding the recommended dose of over-the-counter (OTC) sodium phosphate products to treat constipation.

There have been reports of severe dehydration and changes in serum electrolyte levels from taking more than the recommended dose of OTC sodium phosphate products, resulting in serious adverse effects on organs, such as the kidneys and heart, and in some cases resulting in death.
