Lesinurad/allopurinol - oral
Lesinurad/allopurinol - oral
One ingredient in this combination product, lesinurad, has caused very serious kidney problems. Tell your doctor right away if you notice any signs of kidney problems, such as lower back pain, nausea/vomiting, painful/difficult urination, change in the amount of urine.
This medication is a combination of 2 ingredients: lesinurad and allopurinol. 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.
