Daprodustat

Using daprodustat increases the risk that blood clots will form in or move to the legs, lungs, or brain. Tell your doctor if you have or have ever had heart disease and if you have ever had a stroke. Call your doctor immediately or get emergency medical help if you experience any of the following symptoms: pain, tenderness, redness, warmth, and/or swelling in the legs; coolness or paleness in an arm or leg; shortness of breath; cough that won't go away or that brings up blood; chest pain; sudden trouble speaking or understanding speech; sudden confusion; sudden weakness or numbness of an arm or leg (especially on one side of the body) or of the face; sudden trouble walking, dizziness, or loss of balance or coordination; or fainting. If you are being treated with hemodialysis (treatment to remove waste from the blood when the kidneys are not working), a blood clot may form in your vascular access (place where the hemodialysis tubing connects to your body). Tell your doctor if your vascular access stops working as usual.

Your doctor will adjust your dose of daprodustat so that your hemoglobin level (amount of a protein found in red blood cells) is just high enough that you do not need a red blood cell transfusion (transfer of one person's red blood cells to another person's body to treat severe anemia). If you receive enough daprodustat to increase your hemoglobin to a normal or near normal level, there is a greater risk that you will have a stroke or develop serious or life-threatening heart problems including heart attack, and heart failure. Call your doctor immediately or get emergency medical help if you experience any of the following symptoms: chest pain, squeezing pressure, or tightness; shortness of breath; nausea, lightheadedness, sweating, and other early signs of heart attack; discomfort or pain in the arms, shoulder, neck, jaw, or back; or swelling of the hands, feet, or ankles.

Keep all appointments with your doctor and the laboratory. Your doctor will order certain lab tests to check your body's response to daprodustat. Your doctor may decrease your dose or tell you to stop using daprodustat for a period of time if the tests show that you are at high risk of experiencing serious side effects. Follow your doctor's directions carefully.

Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with daprodustat and each time you refill your prescription. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website (https://www.fda.gov/Drugs/DrugSafety/ucm085729.htm) to obtain the Medication Guide.

Talk to your doctor about the risks of taking daprodustat.

Daprodustat is used to treat anemia (a lower than normal number of red blood cells) in people with chronic kidney failure (condition in which the kidneys slowly and permanently stop working over a period of time) who have been receiving hemodialysis for at least 4 months Daprodustat is in a class of medications called HIF PH inhibitors. It works by increasing the hormone, erythropoietin, needed by the body to produce more red blood cells.

Daprodustat comes as a tablet to take by mouth. It is usually taken with or without food one time a day. Take daprodustat at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take daprodustat 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 will likely have to adjust your dose of daprodustat periodically based on your lab work.

Daprodustat controls anemia but does not cure it. Continue to take daprodustat even if you feel well. Do not stop taking daprodustat without talking to your doctor.

This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
