Auryxia and Entereg

• Generic Name: ferric citrate
• Dosage Forms: tablet, coated
• Other Brand Names: 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.

Entereg (alvimopan) reduces certain side effects of narcotic medicines that are often used to prevent pain caused by surgery. Narcotic medicine can cause stomach pain, bloating, nausea, vomiting, and constipation. These side effects can delay recovery in patients undergoing gastrointestinal surgery.

Entereg helps prevent these side effects without reducing the pain-relieving effects of the narcotic.

Entereg is used to help restore normal digestive functioning after surgery to remove a portion of your intestine. This medicine is available only under a special program for short-term use (no more than 15 doses). You must be registered in the program and understand the risks and benefits of taking this medicine.
