What is Allopurinol-Lesinurad used for?

Allopurinol-Lesinurad is a combination medication. It works by decreasing the amount of uric acid your body makes, and by helping the kidneys get rid of uric acid. Increased uric acid levels can cause gout attacks. This combination medication is used to lower uric acid when allopurinol alone has not worked well enough. This effect helps prevent gout flares/attacks.

How should I take Allopurinol-Lesinurad?

Take this medication by mouth with food as directed by your doctor, usually once daily in the morning with a full glass of water (240 milliliters). Drink plenty of fluids (at least 8 full glasses a day) while taking this medication to help it work better, unless otherwise directed by your doctor.

If you are switching from taking lesinurad or allopurinol to this combination product, be sure to stop taking the other lesinurad or allopurinol product to avoid taking too much medication(s) and increasing the risk of side effects.

You may have more gout attacks for several months after you start taking this medicine while your body gets rid of extra uric acid. Do not stop taking this medication if you have a gout flare/attack. This medication is not for treating gout attacks. Your doctor may prescribe other medication (including colchicine, NSAIDs such as ibuprofen, naproxen, or indomethacin) to prevent or treat a gout attack while you are taking this medication. Continue to take lesinurad/allopurinol and your prescribed medicines for gout attacks as directed by your doctor. Tell your doctor if your condition does not get better or if it gets worse.
