What Is Potassium Phosphate?

Phosphorus is a naturally occurring substance that is important in every cell of the body. Phosphorous is contained in all potassium dihydrogen phosphate;body cells and is used for growth and repair of cells and tissues.

Potassium phosphate is used to treat or prevent hypophosphatemia (low blood levels of phosphorus). Potassium phosphate is sometimes added to intravenous (IV) fluids given to people who cannot eat or drink anything.

Potassium phosphate and sodium phosphate may also be used for purposes not listed in this medication guide.

You should not use potassium phosphate if you have low levels of calcium, or high levels of potassium or phosphorus in your body.
