Vafseo (vadadustat) is a hypoxia-inducible factor prolyl hydroxylase inhibitor (HIF-PHI). It's used to treat anemia in adults with chronic kidney disease (CKD) who are on dialysis. It comes as a tablet that's taken by mouth once a day. Side effects include high blood pressure and diarrhea. This medication is only available as a brand-name version.
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.
The following side effects may get better over time as your body gets used to the medication. Let your healthcare provider know immediately if you continue to experience these symptoms or if they worsen over time.
Contact your healthcare provider immediately if you experience any of the following.

Side effects that usually do not require medical attention (report these to your care team if they continue or are bothersome):
Studies show that Vafseo (vadadustat) works just as well as Aranesp (darbepoetin alfa) for treating people with anemia from CKD on dialysis. In the study, Vafseo (vadadustat) helped raise and keep hemoglobin levels in the target range of 10 g/dL to 11 g/dL. Talk to your prescriber if you have questions about how well Vafseo (vadadustat) works for you.
In a study, Vafseo (vadadustat) started to slowly raise hemoglobin levels on average within a few weeks. But it can take months for levels to reach the target range of 10 g/dL to 11 g/dL and stay within this level. Your prescriber will order regular blood tests to check your hemoglobin levels. This helps them see how well the medication is working for you. Keep taking Vafseo (vadadustat) every day as prescribed, even if your hemoglobin levels don't go up right away. Talk to your prescriber if you have questions about how fast the medication should work.
No. Vafseo (vadadustat) isn't recommended for people with anemia from CKD who aren't on dialysis. In studies, people not on dialysis had a higher risk of life-threatening problems when taking Vafseo (vadadustat) compared to another anemia medication. These risks included death, heart attack, stroke, and serious kidney, liver, and stomach problems. If you aren't on dialysis, talk to your CKD specialist about other treatment options. These can include ESA medications or blood transfusions.
In studies, hair loss wasn't a side effect people had while taking Vafseo (vadadustat). If you notice hair loss, hair shedding, or hair thinning during treatment, tell your care team. They can help figure out what might be causing it.
No, weight gain isn't an expected side effect from Vafseo (vadadustat). If you notice unusual weight gain, talk to your primary care provider. They'll ask you questions to help figure out what might be causing it and help you manage your weight.
If you're pregnant or thinking of getting pregnant, talk to your care team. It's not clear how safe Vafseo (vadadustat) is during pregnancy. Your prescriber can help you understand the risks and benefits of treatment. In general, Vafseo (vadadustat) should only be used during pregnancy if the benefits are greater than the risks.
Don't breastfeed while taking Vafseo (vadadustat) and for at least 2 days after your last dose. We don't know if the medication can get into breast milk and if there could be side effects in your baby if it does. Talk to your prescriber or a lactation consultant about other ways to feed your baby. One possibility is using baby formula instead.
Vafseo (vadadustat) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Vafseo (vadadustat) can raise the risk of serious blood clot problems, which can be life-threatening. These problems can include blood clots, heart attacks, or strokes.
Before you start Vafseo (vadadustat), tell your prescriber about your full medical history. Your risk is higher if you've had heart problems or issues with blood flow to the brain. You shouldn't start this medication if you've had a heart attack or stroke in the last 3 months.
To lower your risk, your prescriber will try to find the lowest dose of Vafseo (vadadustat) that works for you and helps you avoid blood transfusions. They'll also check your hemoglobin levels. This makes sure your levels don't get too high, since that can also put you at risk of clots.
Know the signs and symptoms of a blood clot or related problem. They can happen in the legs, lungs, heart, or brain.
If you notice any signs of a serious blood clot or a problem related to blood clots, get medical help right away.
Although rare, Vafseo (vadadustat) can cause higher liver enzyme levels in your blood. This can be a sign of damage to your liver. In studies, a few people had serious liver problems within the first 3 months of treatment. They didn't have any symptoms, and the liver problems went away after they stopped taking the medication.
Before starting Vafseo (vadadustat), tell your prescriber about your medical history. You'll also need a blood test so they can check your liver function. This medication isn't recommended if you have liver cirrhosis or liver disease.
During treatment, you'll need lab tests done periodically to check for liver problems. If they show liver damage, you might have to stop Vafseo (vadadustat) to prevent further harm.
Watch for signs and symptoms of liver damage while taking Vafseo (vadadustat). Get medical help right away if you feel more tired than usual or have pain in your upper right stomach, low appetite, yellow skin or eyes, or dark urine.
Vafseo (vadadustat) can raise your blood pressure and sometimes make it dangerously high. Before starting this medication, tell your prescriber if you have high blood pressure. They need to make sure it's safe for you. You can't take Vafseo (vadadustat) if your blood pressure isn't well controlled.
While taking Vafseo (vadadustat), regularly check your blood pressure at home. Tell your care team if your blood pressure stays higher than usual. You might need to start a blood pressure medication. Or, your prescriber might need to change your blood pressure medication if you already take one.
Get medical help right away if you have a severe headache, sudden weakness or numbness, blurry vision, chest pain, trouble breathing, nausea, or confusion. These can be signs of dangerously high blood pressure.
Although rare, some people who took Vafseo (vadadustat) had a seizure. Let your prescriber know if you've had a seizure in the past.
Get medical help as soon as possible if you have a seizure or have seizures more often while taking Vafseo (vadadustat). Also look out for a "funny feeling”, headache, confusion, anxiety, or irritability. These can appear before a seizure happens.
In studies, some people taking Vafseo (vadadustat) had damage to their digestive tract. This included ulcers in the esophagus (the tube that connects your throat to your stomach). It also caused damage to the stomach's protective lining. This sometimes led to serious stomach bleeding.
The risk is higher if you've had stomach problems like ulcers before. It's also higher if you take other medications that can irritate the stomach. These include nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen (Advil) or naproxen (Aleve).
Get medical help right away if you have signs or symptoms of esophagus or stomach ulcers or stomach bleeding. Watch for trouble or pain when swallowing, heartburn, or stomach or chest pain. Also be aware if you feel unusually tired or faint. Call 911 right away if you have bloody vomit, bloody or black stools, or severe stomach pain that doesn't go away.
