What Febuxostat is and what it is used for

Febuxostat contains the active substance febuxostat and is 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
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.
Febuxostat 120 mg is also used to treat and prevent high blood levels of uric acid that may occur when
you start to receive chemotherapy for blood cancers.
When chemotherapy is given, cancer cells are destroyed, and uric acid levels increase in the blood
accordingly, unless the formation of uric acid is prevented.
Febuxostat is for adults.


What you need to know before you take Febuxostat

Do not take Febuxostat:
 if you are allergic to febuxostat or any of the other ingredients of this medicine (listed in section
Warnings and precautions
Talk to your doctor before taking Febuxostat if you
 have or have had heart failure or heart problems
 have or have had renal disease and/or serious allergic reaction to Allopurinol (a medication used
for the treatment of Gout)
V1.1 – Change of Ownership

have or have had liver disease or liver function test abnormalities
are being treated for high uric acid levels as a result of Lesch-Nyhan syndrome (a rare inherited
condition in which there is too much uric acid in the blood)
have thyroid problems.

Should you experience allergic reactions to Febuxostat, stop taking this medicine (see also section 4).
Possible symptoms of allergic reactions might be:
 rash including severe forms (e.g. blisters, nodules, itchy-, exfoliative rash), itchiness
 swelling of limbs or face
 difficulties in breathing
 fever with enlarged lymph nodes
 but also serious life threatening allergic conditions with cardiac and circulatory arrest.
Your doctor might decide to permanently stop treatment with Febuxostat.
There have been rare reports of potentially life-threatening skin rashes (Stevens-Johnson Syndrome)
with the use of febuxostat, appearing initially as reddish target-like spots or circular patches often with
central blister on the trunk. It may also include ulcers in the mouth, throat, nose, genitals and
conjunctivitis (red and swollen eyes). The rash may progress to widespread blistering or peeling of the
If you have developed Stevens-Johnson Syndrome with the use of febuxostat, you must not be restarted on febuxostat at any time. If you developed a rash or these skin symptoms, seek immediate
advice from a doctor and tell that you are taking this medicine.
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
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).
In patients with very high urate levels (e.g. those undergoing cancer chemotherapy), treatment with
uric acid-lowering medicines could lead to the build-up of xanthine in the urinary tract, with possible
stones, even though this has not been observed in patients being treated with febuxostat for Tumor
Lysis Syndrome.
Your doctor may ask you to have blood tests to check that your liver is working normally.
Children and adolescents
Do not give this medicine to children under the age of 18 because the safety and efficacy have not
been established.
Other medicines and Febuxostat
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other
medicines, including medicines obtained without a prescription.
It is especially important to tell your doctor or pharmacist if you are taking medicines containing any
of the following substances as they may interact with Febuxostat and your doctor may wish to
consider necessary measures:
 Mercaptopurine (used to treat cancer)
 Azathioprine (used to reduce immune response)
 Theophylline (used to treat asthma).

doctor will have prescribed the strength most suitable for you.
The usual dose is one tablet daily.
Continue to take Febuxostat every day even when you are not experiencing gout flare or attack.
Prevention and treatment of high uric acid levels in patients undergoing cancer chemotherapy
The usual dose is one 120 mg film-coated tablet daily.
Start taking Febuxostat two days before chemotherapy and continue its use according to your doctor’s
advice. Usually treatment is short-term.
Method of administration

In the event of an accidental overdose ask your doctor what to do, or contact your nearest accident and
emergency department.
If you forget to take Febuxostat
If you miss a dose of Febuxostat take it as soon as you remember unless it is almost time for your next

If you stop taking Febuxostat
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.
