International non-proprietary name: Febuxostat

On prescription

Read carefully before use


Febuxostat-NAN 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.

Febuxostat-NAN works by reducing uric acid levels. Keeping uric acid levels low by taking Febuxostat-NAN 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-NAN 120 mg tablets 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-NAN is for adults.

Do not take Febuxostat-NAN

  • If you are allergic to febuxostat or any of the other ingredients of this medicine (listed in section 6).

Warnings and precautions

Talk to your doctor before taking Febuxostat-NAN:

  • If you have or have had heart failure, heart problems or stroke.
  • If you have or have had renal disease and/or serious allergic reaction to Allopurinol (a medication used for the treatment of Gout).
  • If you have or have had liver disease or liver function test abnormalities.
  • If you 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).
  • If you have thyroid problems.

Should you experience allergic reactions to Febuxostat-NAN, 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-NAN.

There have been rare reports of potentially life-threatening skin rashes (Stevens-Johnson Syndrome) with the use of Febuxostat-NAN, 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 must not be restarted on Febuxostat-NAN at any time. If you develop 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 Febuxostat-NAN.

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-NAN, and especially during the first weeks or months of treatment. It is important to keep taking Febuxostat-NAN even if you have a flare, as Febuxostat-NAN is still working to lower uric acid. Over time, gout flares will occur less often and be less painful if you keep taking Febuxostat-NAN 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-NAN for Tumor Lysis Syndrome.

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

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-NAN. In that case your doctor may wish to consider necessary measures:

  • Mercaptopurine (used to treat cancer).
  • Azathioprine (used to reduce immune response).
  • Theophylline (used to treat asthma).

Prevention and treatment of high uric acid levels in patients undergoing cancer chemotherapy

Febuxostat-NAN is available as 120 mg tablet.
Start taking Febuxostat-NAN two days before chemotherapy and continue its use according to your doctor’s advice. Usually, treatment is short-term.
The score line on the 80 mg tablet is only there to help you break the tablet if you have difficulty swallowing it whole.

If you take more Febuxostat-NAN tablets than you should

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-NAN

If you miss a dose of Febuxostat-NAN 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.

If you stop taking Febuxostat-NAN

Do not stop taking Febuxostat-NAN without the advice of your doctor even if you feel better. If you stop taking Febuxostat-NAN 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.
If you have any further questions on the use of Febuxostat-NAN, ask your doctor or pharmacist.
