1. What Febuxostat cinfamed is and what it is used for

This medicine contains the active substance febuxostat and is used to treat gout, a condition associated with excess of a chemical compound in the body called uric acid (urate). In some people, uric acid accumulates in the blood to the point where it can no longer dissolve. When this occurs, urate crystals form both within and around joints and in the kidneys. These crystals can cause sudden and severe pain, redness, warmth, and swelling in the joints (known as gout attacks). If left untreated, large deposits called tophi may form around and within the joints. Tophi can damage joints and bones.

This medicine works by lowering the concentration of uric acid. Keeping uric acid levels low by taking Febuxostat cinfamed once daily helps prevent 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.

This medicine is for use in adults.

2. What you need to know before taking Febuxostat cinfamed

Do not take Febuxostat cinfamed:

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

Warnings and precautions

Talk to your doctor or pharmacist before taking Febuxostat cinfamed:

• 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 impaired liver function.
• if you are being treated for high levels of uric acid due to Lesch-Nyhan syndrome (a rare inherited condition in which there is too much uric acid in the blood).
• if you have thyroid problems.

If you experience allergic reactions to Febuxostat cinfamed, stop taking this medicine (see also section 4). Possible symptoms of allergic reactions may include:

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

Rare cases of life-threatening skin rashes (Stevens-Johnson syndrome) have been reported with the use of febuxostat. These rashes typically begin on the trunk as reddish, target-shaped spots or circular lesions, often with a blister in the center. They may also include mouth ulcers, throat, nose, genital sores, and conjunctivitis (red, swollen eyes). The rash may progress to widespread blistering or skin peeling.

If you have developed Stevens-Johnson syndrome while using febuxostat, you must never restart treatment with Febuxostat. If you develop a rash or these skin symptoms, seek immediate medical attention and inform your doctor that you are taking this medicine.

If you experience a gout attack (sudden, intense pain accompanied by tenderness, redness, warmth, and swelling in a joint), wait until the attack subsides before starting treatment with febuxostat.

Some people may experience a gout attack when beginning treatment with medicines that control uric acid levels. Not everyone experiences these attacks, but they may occur even while taking febuxostat, especially during the first weeks or months of treatment. It is important to continue taking febuxostat even if you have a gout attack, as this medicine continues to work to reduce uric acid. With daily use of febuxostat, gout attacks will become less frequent and less severe over time.

If needed, your doctor may prescribe additional medicines to prevent or treat symptoms of gout attacks (such as joint pain and swelling).

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

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

If you stop taking Febuxostat cinfamed

Even if you feel better, do not stop taking febuxostat unless instructed by your doctor. If you stop taking febuxostat, uric acid levels may rise again, and symptoms may worsen due to the formation of new urate crystals in the joints and kidneys.
