6.Contents of the package and additional information

Febuxostat Stada tablets contain the active ingredient febuxostat and are 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 sudden and intense pain, redness, heat, and swelling in the joints (this is called gout attacks). If left untreated, large deposits called tophi can form around the joints and inside them. Tophi can damage the joints and bones.

Febuxostat works by reducing the concentration of uric acid. Maintaining low uric acid levels by taking febuxostat once a day slows the formation of crystals and, over time, reduces symptoms. If uric acid levels are kept low for a sufficient period, the size of tophi also decreases.

Febuxostat is for adults.

Do not take Febuxostat Stada

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

Warnings and precautions

Consult your doctor before starting to take febuxostat:

• if you have or have had heart failure, heart problems or stroke
• if you have or have had kidney disease and/or severe allergic reactions to allopurinol (a medicine 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 medicine (see also section 4). Possible symptoms of allergic reactions may be:

• skin rash including severe forms (e.g. blisters, nodules, exfoliative rash that causes 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.

Stevens-Johnson syndrome

Rare cases of life-threatening skin eruptions (Stevens-Johnson syndrome) have been reported with the use of febuxostat. These initially appear on the trunk as red spots in the shape of a target or circular spots that often have 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 evolve into generalized blisters or skin peeling.

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

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 medicines 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 medicine 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 medicines to prevent or treat symptoms of gout attacks (such as joint pain and swelling).

In patients with very high uric acid levels (e.g. those undergoing chemotherapy for cancer), treatment with medicines to reduce uric acid levels may lead to the accumulation of xanthine in the urinary tract, with the possible formation of 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 medicine to children under 18 years of age, as the safety and efficacy have not been established.

Other medicines and Febuxostat Stada

If You Forget to Take Febuxostat Stada

If You Interrupt Treatment with Febuxostat Stada

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 level may increase again, and symptoms may worsen due to the formation of new urate crystals in the joints and kidneys.
