How Vafseo (vadadustat) works
Vafseo (vadadustat) is a hypoxia-inducible factor prolyl hydroxylase inhibitor, or HIF-PHI. It works by keeping the levels of a protein called HIF high enough in the body. This helps raise the amount of erythropoietin (EPO), a hormone that tells your body to make more red blood cells. Making more red blood cells helps treat anemia caused by chronic kidney disease.

Pharmacist tips for Vafseo (vadadustat)

- Take Vafseo (vadadustat) with or without food. If it's hurting your stomach, try taking it with food to help.
- Swallow the Vafseo (vadadustat) tablet whole. Don't crush, cut, or chew it. If you have trouble swallowing tablets, talk to your prescriber.
- Mark your calendar for your blood work appointments while taking Vafseo (vadadustat). These tests are important to make sure the medication is working and is safe for you. The tests will check your hemoglobin levels, iron levels, and liver labs. Your prescriber might change your dose based on your results.
- Check your blood pressure as your prescriber tells you to. Vafseo (vadadustat) can make your blood pressure go up, sometimes to dangerous levels. If your blood pressure stays high, tell your care team. Your prescriber can help manage it, including using blood pressure medications if needed.
- Vafseo (vadadustat) often causes diarrhea. If this happens, make sure to stay hydrated. Ask a healthcare professional if you're considering anti-diarrhea medications to help. Talk to your prescriber if diarrhea doesn't improve or if you feel dizzy or lightheaded.
- Try to avoid alcohol while taking Vafseo (vadadustat). Both the medication and alcohol can raise your risk of serious problems, like stomach and liver damage. Talk to your prescriber about your drinking habits and how to take Vafseo (vadadustat) in a safe way.
- Take Vafseo (vadadustat) at least 1 hour before any products that contain iron. This includes iron supplements and iron-based phosphate binders like Auryxia (ferric citrate) and Velphoro (sucroferric oxyhydroxide). Iron can lower how much Vafseo (vadadustat) your body absorbs. This can make the medication work less well.
- Take Vafseo (vadadustat) at least 1 hour before or 2 hours after taking a phosphate binder that's not iron based. Examples include calcium acetate or sevelamer carbonate (Renvela). Taking them at different times helps Vafseo (vadadustat) get absorbed into the body properly so it can work the way it should.
- Make sure to tell your care team about all the medications you take or plan to take. Some medications can interact with Vafseo (vadadustat) and raise your risk of side effects.

Your care team can suggest changes to your medications to keep you safe if needed.
