What is lesinurad?

Lesinurad helps the kidneys remove uric acid from the body. Lesinurad is used together with other medicines that can cause the body to produce less uric acid.

Lesinurad is used as part of a combination of medicines to treat high levels of uric acid in your blood, also called hyperuricemia (HYE-per-URE-i-SEE-mee-a). High levels of uric acid can lead to a condition called gout.

Lesinurad should be used together with allopurinol (Zyloprim) or febuxostat (Uloric). Lesinurad should not be used alone.

Lesinurad may also be used for purposes not listed in this medication guide.


You should not use lesinurad if you have severe kidney problems, or if you are on dialysis or have received a kidney transplant.

Lesinurad can cause kidney failure, especially if you take it without your other prescribed medications. Call your doctor right away if you urinate less than usual or not at all, or if you have swelling in your feet or ankles, or shortness of breath.

Before taking this medicine

You should not use lesinurad if you are allergic to it, or if:

  • you have severe kidney disease;

  • you are on dialysis;

  • you received a kidney transplant;

  • you have Lesch-Nyhan syndrome (a genetic condition that increases uric acid levels in the blood); or

  • you have tumor lysis syndrome (rapid breakdown of cancer cells).

To make sure lesinurad is safe for you, tell your doctor if you have ever had:

It is not known whether this medicine will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant.

Lesinurad can make birth control pills less effective. Ask your doctor about using a non hormonal birth control (condom, diaphragm with spermicide) to prevent pregnancy.

Other forms of hormonal contraception (injections, implants, skin patches, vaginal rings, and certain intrauterine devices) may not be effective enough to prevent pregnancy during your treatment with lesinurad.

It is not known whether lesinurad passes into breast milk or if it could harm a nursing baby. Tell your doctor if you are breast-feeding a baby.

Lesinurad is not approved for use by anyone younger than 18 years old.

How should I take lesinurad?

Follow all directions on your prescription label. Do not use lesinurad in larger or smaller amounts or for longer than recommended.

Use all medications as directed by your doctor. Read the medication guide or patient instructions provided with each medication. Do not change your doses or medication schedule without your doctor's advice.

Lesinurad should be given in combination with other uric acid medication and it should not be used alone. Lesinurad is more likely to cause kidney failure if you take this medicine without your other prescribed medication.

Lesinurad works best if you take it with food and water. Take lesinurad in the morning with your other medicine to control uric acid.

Drink at least 2 liters (68 ounces) of liquids every day to keep your kidneys working properly.

Gout symptoms may get worse when you first start taking lesinurad. Even if you have a gout flare-up, keep using the medication as directed.

Call your doctor if your gout symptoms do not eventually improve.

You may need medical tests to check your kidney function before and during treatment with lesinurad.

Store at room temperature away from moisture, heat, and light.

What happens if I miss a dose?

Skip the missed dose if morning has already passed. Do not take lesinurad later in the day. Wait until the next day to take your next scheduled dose. Do not take extra medicine to make up the missed dose.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.

What should I avoid while taking lesinurad?

Avoid becoming dehydrated while taking lesinurad. Call your doctor if you have ongoing vomiting or diarrhea, or if you are sweating more than usual. Dehydration could lead to kidney failure.
