You may experience gout flare when you first start taking Febuxostat, as the urate crystals start to dissolve and are “shed” into the blood stream again as uric acid. This shows that the drug is working, and these will soon become less frequent over time with regular use of Febuxostat. To prevent this, your doctor may prescribe other medicines, such as non-steroidal anti-inflammatory drugs (NSAIDs) or colchicine with Febuxostat for the first 6 months.

Your doctor will perform blood tests before and after you start taking Febuxostat to monitor uric acid levels and side effects. Do come back to the hospital for regular follow-ups and blood tests as instructed by your doctor.
There are a number of lifestyle changes that help to reduce the risk of having a gout attack.

Your doctor, specialty nurse, or pharmacist will advise you about the changes which could benefit you.
