Febuxostat tablets are drugs that inhibit the production of uric acid and have the effect of lowering blood uric acid, and can be used for the treatment of gout in remission. However, it is generally not recommended to use such drugs during acute attacks of gout, because febuxostat has the effect of dissolving uric acid crystals, which can cause fluctuations in uric acid, resulting in prolonged or aggravated gout attacks. In addition, during the gout remission period, if the first use of febuxostat may also lead to gout attacks, it is generally not necessary to stop the drug at this time, you can add colchicine or non-steroidal drugs to relieve pain. In addition, strict dietary control, such as do not drink alcohol, do not eat food containing too much purine. If necessary, 24h urinary uric acid can be further checked to clarify whether it is suitable to take febuxostat, and if it is the type with impaired uric acid excretion, it needs to be replaced with benzbromarone tablets to continue treatment.
