|Information for patients
FEBUXOSTAT tablets are used to treat gout, which is associated with an excess of a chemical called uric acid (urate) in the body. In some people, the amount of uric acid builds up in the blood and may become too high to remain soluble. When this happens, urate crystals may form in and around the joints and kidneys. These crystals can cause sudden, severe pain, redness, warmth and swelling in a joint (known as a gout attack). Left untreated, larger deposits called tophi (TOE-FI) may form in and around joints. These tophi may cause joint and bone damage. FEBUXOSTAT works by reducing uric acid levels. Keeping uric acid levels low by taking FEBUXOSTAT once every day stops crystals building up, and over time it reduces symptoms. Keeping uric acid levels sufficiently low for a long enough period can also shrink tophi.
|Before Consuming the Medicine
||•If you are allergic (hypersensitive) to febuxostat, the active ingredient of FEBUXOSTAT, or any of the other ingredients in these tablets.
|Drug Special Care
||Tell your doctor before you start to take this medicine:
•If you have or have had heart failure or heart problems
•If you are being treated for high uric acid levels as a result of cancer disease or Lesch-Nyhan syndrome (a rare inherited condition in which there is too much uric acid in the blood)
•If you have thyroid problems
If you are having a gout attack at the moment (a sudden onset of severe pain, tenderness, redness, warmth and swelling in a joint), wait for the gout attack to subside before first starting treatment with FEBUXOSTAT. For some people, gout attacks may flare up when starting certain medicines that control uric acid levels. Not everyone gets flares, but you could get a flare-up even if you are taking FEBUXOSTAT, and especially during the first weeks or months of treatment. It is important to keep taking FEBUXOSTAT even if you have a flare, as FEBUXOSTAT is still working to lower uric acid. Over time, gout flares will occur less often and be less painful if you keep taking FEBUXOSTAT every day.
Your doctor will often prescribe other medicines, if they are needed, to help prevent or treat the symptoms of flares (such as pain and swelling in a joint). Your doctor may ask you to have blood tests to check that your liver is working normally.

It is important that you do not stop taking FEBUXOSTAT unless your doctor tells you to.
Continue to take FEBUXOSTAT every day even when you are not experiencing gout flare or attack.
|Excess Drug Consumption
||In the event of an accidental overdose ask your doctor what to do, or contact your nearest accident and emergency department.
|Forgot Drug Consumption
||If you miss a dose of FEBUXOSTAT take it as soon as you remember unless it is almost time for your next dose, in which case miss out the forgotten dose and take your next dose at the normal time. Do not take a double dose to make up for a forgotten dose.
|Stop Drug Consumption
||Do not stop taking FEBUXOSTAT without the advice of your doctor even if you feel better. If you stop taking FEBUXOSTAT your uric acid levels may begin to rise and your symptoms may worsen due to the formation of new crystals of urate in and around your joints and kidneys.
