Febuxostatcontains the active ingredient febuxostat and is used to treat gout, which is associated with an excess of a chemical compound called uric acid (urate) in the body. In some people, uric acid accumulates in the blood to the point where it cannot be dissolved. When this occurs, urate crystals form both inside and around the joints and kidneys. These crystals can cause a sudden and intense pain, redness, heat, and swelling in the joints (known as a gout attack). If left untreated, large deposits called tophi can form around the joints and inside them. Tophi can damage the joints and bones.

Febuxostatacts by reducing the concentration of uric acid. Maintaining a low concentration of uric acid by takingfebuxostat once a day slows the formation of crystals and, over time, reduces symptoms. If the concentration of uric acid is kept low for a sufficient period, the size of the tophi also decreases.

Febuxostat is for adults..

Do not take Febuxostat:

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

Warnings and precautions

Consult your doctor or pharmacist before starting to take febuxostat:

• if you have or have had heart failure or other heart problems
• if you have or have had kidney disease and/or severe allergic reactions to allopurinol (a medication used to treat gout)
• if you have or have had liver disease or liver function abnormalities
• if you are being treated for high uric acid levels due to Lesch-Nyhan syndrome (a rare genetic disorder in which there is too much uric acid in the blood)
• if you have thyroid problems

If you experience allergic reactions to febuxostat, stop taking this medication (see also section 4).

Possible symptoms of allergic reactions may include:

• skin rash, including severe forms (e.g. blisters, nodules, exfoliative rashes that cause itching), itching
• swelling of the limbs or face
• difficulty breathing
• fever with enlarged lymph nodes
• also severe allergic reactions that can be life-threatening, associated with cardiac arrest.

Your doctor may decide to permanently discontinue treatment with febuxostat.

Rare cases of life-threatening skin eruptions (Stevens-Johnson syndrome) have been reported with the use of febuxostat, initially appearing on the trunk as red spots in the shape of a bull's-eye or circular spots often with a blister in the center. It may also include ulcers in the mouth, throat, nose, genitals, and conjunctivitis (red and swollen eyes). The rash may progress to generalized blisters or skin peeling.

If you have developed Stevens-Johnson syndrome with the use of febuxostat, do not restart treatment at any time. If you develop a rash or these symptoms on your skin, go to your doctor immediately and tell them that you are taking this medication.

If you experience a gout attack (a sudden onset of intense pain accompanied by sensitivity, redness, heat, and swelling of a joint), wait for the attack to subside before starting treatment with febuxostat.

Some people may experience a gout attack when starting certain medications that control uric acid levels. Not everyone experiences these attacks, but they can occur even while taking febuxostat, especially during the first weeks or months of treatment. It is essential to continue taking febuxostat daily, as this medication continues to act to reduce uric acid levels. If you continue to take febuxostat, gout attacks will become less frequent and less painful.

If necessary, your doctor will prescribe other medications to prevent or treat gout attack symptoms (such as joint pain and swelling).

In patients with very high uric acid levels (e.g. those undergoing chemotherapy for cancer), treatment with medications to reduce uric acid levels may lead to the accumulation of xanthine in the urinary tract, potentially forming stones, although this has not been observed in patients treated with febuxostat for tumor lysis syndrome.

Your doctor may perform blood tests to check that your liver is functioning normally.

Children and adolescents

Do not administer this medication to children under 18 years of age, as the safety and efficacy have not been established.

Febuxostat with other medications

Inform your doctor or pharmacist if you are taking, have taken recently, or may need to take any other medication, including those purchased without a prescription.

It is especially important to inform your doctor or pharmacist if you are taking medications containing any of the following substances, as they may interact with febuxostat, and your doctor may need to take special measures:

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

If you forget to take Febuxostat

If you forget a dose of febuxostat, take it as soon as you remember, unless it is almost time to take the next one; in that case, skip the missed dose and take the next one at the usual time. Do not take a double dose to compensate for the missed doses.

If you interrupt treatment with Febuxostat

Although you may be feeling better, do not stop taking febuxostat unless your doctor tells you to. If you stop taking febuxostat, your uric acid concentration may increase again, and symptoms may worsen due to the formation of new urate crystals in the joints and kidneys.

If you have any other questions about the use of this medication, ask your doctor or pharmacist.
