Lesinurad may cause serious kidney problems. Tell your doctor if you are being treated with dialysis (treatment to clean the blood when the kidneys are not working well), have received a kidney transplant, or have or have ever had kidney disease. The risk that you will develop serious kidney problems is greater if you are taking lesinurad alone. Lesinurad must be taken in combination with a xanthine oxidase inhibitor such as allopurinol (Lopurin, Zyloprim) or febuxostat (Uloric). If you experience any of the following symptoms, call your doctor immediately: nausea, vomiting, or upper right stomach pain.
Keep all appointments with your doctor and the laboratory. Your doctor may order certain tests before and during treatment to check your body's response to lesinurad.
Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with lesinurad 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 (http://www.fda.gov/Drugs/DrugSafety/ucm085729.htm) to obtain the Medication Guide.
WHY is this medicine prescribed?
Lesinurad is used in combination with a xanthine oxidase inhibitor to treat hyperuricemia (high levels of uric acid) in people with gout (sudden attacks of redness, swelling, pain, and heat in one or more joints) whose disease is not controlled with their current medication. Lesinurad is in a class of medications called selective uric acid reabsorption inhibitors. It works by helping the kidneys to remove uric acid from the body.
HOW should this medicine be used?
Lesinurad comes as a tablet to take by mouth. It is usually taken once daily in the morning with food and water. Take lesinurad at around the same time every day and at the same time that you take a xanthine oxidase inhibitor such as allopurinol (Lopurin, Zyloprim) or febuxostat (Uloric). Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take lesinurad exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Lesinurad controls hyperuricemia in people with gout but does not cure it. Your gout may flare up (intense painful, swelling joint) when you first start taking lesinurad, but do not stop taking it. Your doctor will give you other medications to help prevent gout flares. Continue to take lesinurad even if you feel well or have a gout attack. Do not stop taking lesinurad without talking to your doctor.
