Lesinurad: Uses, Side Effects

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. 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.

Important Information

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.

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.
