Generic Name: ferric citrate (FER ik SIT rate)
Brand Name: Auryxia

Medically reviewed on May 2, 2018

What is Auryxia?

Auryxia contains iron that binds to the phosphates you take in through food, which helps your body absorb fewer phosphates. This can lower the amount of phosphorus (a mineral) in your blood.

Auryxia is used to control phosphorus levels in adults with chronic kidney disease who are on dialysis.

Auryxia is also used to treat iron deficiency anemia in adults with chronic kidney disease who are not on dialysis.

Auryxia may also be used for purposes not listed in this medication guide.
