Benzbromarone is mainly used for the treatment of hyperuricemia, gout and gouty arthritis in the non-acute phase. Taking it for three days during this period usually does not cause harm, but if in the acute phase of gout, it may lead to the attack of urinary stones and renal colic and aggravate the condition. When taking benzbromarone, a few patients may experience digestive symptoms such as diarrhea, nausea, stomach discomfort; skin allergy symptoms such as wind mass, rash, itching; liver function abnormalities and other adverse reactions, which require prompt medical attention if the symptoms are severe. If taken during the acute stage of gout, uric acid crystals can be formed due to excessive uric acid in the excreted urine, which can lead to the formation of kidney stones and ureteral stones, further aggravating the condition. In addition, benzbromarone is prohibited for pregnant women, lactating women and patients with moderate to severe renal dysfunction. During oral administration of benzbromarone, liver and kidney functions should be tested regularly, and large amounts of water are required.
