What is febuxostat?

  • The dose of febuxostat is 80 mg once daily.
  • Depending on your response, your doctor may increase your dose after 2 to 4 weeks, to 120 mg once daily.
  • Always take your febuxostat exactly as your doctor has told you. The pharmacy label on your medicine will tell you how much febuxostat to take, how often to take it, and any special instructions.

How to take febuxostat

  • Take febuxostat at the same time each day. It is best taken in the morning.
  • You can take febuxostat with or without food.
  • Keep taking febuxostat every day, to prevent gout attacks. It may take a few weeks before you experience the full benefits of febuxostat.
  • Limit or avoid alcohol while you are taking febuxostat.
  • If you forget to take your tablet, take it as soon as you remember that day.
  • But, if it is nearly time for your next tablet, just take the next tablet at the right time. Do not take double the amount of tablets.
  • Do not stop taking febuxostat suddenly; speak to your doctor or nurse before stopping.

Special instructions

  • When you first start taking febuxostat, you can still have gout attacks. Keep taking febuxostat, since it takes a while to fully work. Your doctor will prescribe additional medication such as a non-steroidal anti-inflammatory (NSAID) or colchicine to settle the attack.    
  • When taking febuxostat you will need to have blood tests to monitor your liver function and uric acid levels.
