Taking febuxostat about a week to lower uric acid, but the specific taking how long can lower uric acid and personal physical condition also has a certain relationship. Febuxostat is a uric acid-lowering drug that can inhibit uric acid synthesis after taking it, and is suitable for the long-term treatment of hyperuricemia in gout patients, and is not recommended for hyperuricemia without clinical symptoms. Generally speaking, if patients with hyperuricemia take it for one week, the level of uric acid in the body will gradually decrease. However, if the patient’s blood uric acid reaches 600-700 μmol/L or higher, the reduction of uric acid level may take longer after taking the drug. In some patients, due to abnormal uric acid excretion, the problem may be partially resolved after taking febuxostat, but the decrease in uric acid will not be particularly significant. The drug is contraindicated in patients being treated with azathioprine and mercaptopurine. Patients can experience adverse reactions such as hearing loss, tinnitus, as well as vertigo when treated with the drug. Note that the drug is not recommended for use in patients with gout during acute attacks. Febuxostat needs to be used under the supervision of a doctor.
