WHY is this medicine prescribed?
Vadadustat is used for treatment of anemia of chronic disease (low red blood cells caused by inflammation from having a disease for longer than 3 months) due to chronic kidney disease (CKD) in adults who have been on dialysis for at least 3 months. Vadadustat is in a class of medications called hypoxia-inducible factor prolyl hydroxylase (HIF PH) inhibitors. It works by increasing the production of red blood cells.
HOW should this medicine be used?
Vadadustat comes as a tablet to take by mouth. It is usually taken with or without food once a day. Take vadadustat at around the same time every day. It can be taken without regards to dialysis schedule. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take vadadustat exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Swallow the tablets whole; do not split, chew, or crush them.
Your doctor may adjust your dose of vadadustat based on your lab results. Your dose will not be increased more frequently than every 4 weeks but may be decreased sooner based on results.
Vadadustat controls anemia but does not cure it. Continue to take vadadustat even if you feel well. Do not stop taking vadadustat without talking to your doctor.

What should I know about STORAGE and DISPOSAL of this medication?
Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. https://www.upandaway.org
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet.
