About Hyperphosphatemia

Your healthcare provider prescribed AURYXIA because you have a high amount of phosphorus in your blood. This condition is called hyperphosphatemia (HI-per-FOZ-fa-TEE-mee-uh).

Phosphorus plays an important role in your body’s ability to function. Most of the phosphorus found in our bodies is present in our bones and comes from the food we eat. Our bodies need phosphorus to maintain our bones, teeth, nerve function, and muscles.

  • When your kidneys are healthy, they know how much phosphorus your body needs and are able to remove the extra phosphorus that is ingested from the foods you eat
  • When you have chronic kidney disease (CKD), your kidneys don’t work as well at removing phosphorus on their own. As a result, phosphorus levels in the blood rise
  • When your phosphorus levels are too high, you develop hyperphosphatemia (high phosphorus)

The Importance of “Getting to Goal”

If you have hyperphosphatemia and CKD and are on dialysis, the goal should be getting your phosphorus levels towards a normal range.

Talk with your healthcare team about how you can take control of your phosphorus levels.

People living with hyperphosphatemia may have symptoms like:

  • Itching
  • Nausea
  • Vomiting
  • Muscle or bone pain
Even if you don’t have symptoms, it is still important
to manage your hyperphosphatemia.

Ways to Manage High Phosphorus

Talk to your doctor

Taking a phosphate binder, like AURYXIA, and working with a dedicated healthcare team may help you reach your phosphorus goal.

Follow a
prescribed diet

Work with your healthcare team on taking your medication consistently and establishing a kidney-friendly diet. Learn how a dietitian can help in the Dietitian Discussion Guide (PDF).

Make healthy
lifestyle choices

Not smoking, staying active, and following a low-phosphorous diet can all be beneficial for your health, and may help manage your hyperphosphatemia.


Dialysis can help you to filter out excess waste from your blood, including phosphorus.
