Read all of this leaflet carefully before
you start taking this medicine because it
contains important information for you.
- Keep this leaflet. You may need to read it
- If you have any further questions, ask
your doctor or pharmacist.
- This medicine has been prescribed for you
only. Do not pass it on to others. It may
harm them, even if their signs of illness

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.

6. Contents of the pack and other information

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.

1. What Febuxostat is and what it is
used for

Your doctor may ask you to have blood tests
to check that your liver is working normally.

Febuxostat tablets contain the active
substance febuxostat and 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
may form in and around joints. These tophi
may cause joint and bone damage.

Children and adolescents
Do not give this medicine to children under
the age of 18 because the safety and
efficacy have not been established.

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 is for adults.
2. 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 6).

levels as a result of Lesch-Nyhan syndrome
(a rare inherited condition in which there is
too much uric acid in the blood)
• If you have thyroid problems.
Should you experience allergic reactions to
Febuxostat, stop taking this medicine

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 skin.
If you have developed Stevens-Johnson
Syndrome with the use of febuxostat, you

If you stop taking Febuxostat
Do not stop taking Febuxostat without the advice

this medicine, ask your doctor or pharmacist.

Febuxostat 120 mg film-coated tablets are
also used to treat and prevent high blood
levels of uric acid that may occur when you
start to receive chemotherapy for blood
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.
