Taking uric acid-lowering drugs as prescribed by the doctor normally will not damage the kidneys, but if you take a large amount of drugs for a long time, it may damage the kidneys.
Uric acid-lowering drugs include drugs that inhibit uric acid synthesis, such as allopurinol and febuxostat, as well as drugs that promote uric acid excretion, such as benzbromarone. After entering the body, the above drugs are mainly excreted through the liver or kidneys, which may cause slight damage to the kidneys, but when taken in accordance with the doctor’s instructions, they generally do not have any effect.
Prolonged use of large quantities of uric acid-lowering drugs, especially in patients with underlying kidney disease, may cause damage to liver and kidney function, so liver and kidney function should be regularly monitored during the use of the drug.
In the process of taking uric acid-lowering drugs, any discomfort, you should stop the drug in time and go to the regular hospital, complete the relevant examination, under the guidance of the doctor for symptomatic treatment.
