80 mg and 120 mg film-coated tablets
1. What Febuxostat Krka is and what it is used for
Febuxostat Krka tablets contain the active substance febuxostat and are used to treat gout, which is associated with an excess in the body of a chemical substance called uric acid (urate). In some people, the amount of uric acid builds up in the blood and can become too high to still be soluble. When this occurs, urate crystals can form in and around joints and kidneys. These crystals can cause sudden, severe pain, redness, heat, and swelling in a joint (this is called a gout attack). If this is not treated, larger deposits called tofi can form in and around joints. These tofi can damage joints and bone tissue.
Febuxostat Krka works by lowering uric acid levels. By taking Febuxostat Krka once every day, uric acid levels are kept low, which prevents the formation of crystals, and over time the symptoms decrease. By keeping uric acid levels low enough for a long time, tofus can also be reduced.
Febuxostat Krka 120 mg tablets are also used to treat and prevent high levels of uric acid in the blood, which may occur when starting chemotherapy for blood cancer.
When chemotherapy is given, the cancer cells are destroyed, and therefore the uric acid levels in the blood rise unless the production of uric acid is prevented.
Febuxostat Krka is used in adults.
2. What you need to know before using Febuxostat Krka
Do not use Febuxostat Krka
- if you are allergic to febuxostat or any of the other ingredients of this medicine (listed in section 6).
Warnings and cautions
Talk to your doctor or pharmacist before taking Febuxostat Krka:
- if you have or have had heart failure, heart problems, or strokes,
- if you have or have had kidney disease and/or a severe allergic reaction to allopurinol (a medicine used to treat gout ),
- if you have or have had liver disease or abnormal liver values,
- if you are treated for high uric acid levels due to Lesch-Nyhan syndrome (a rare hereditary condition that causes too much uric acid in the blood),
- if you have thyroid problems.
If you get an allergic reaction to Febuxostat Krka, stop taking this medicine (see also section 4). Possible symptoms of an allergic reaction are:
- rash including severe forms (eg blisters, lumps, itchy and scaly rash), itching
- swelling in the legs or face
- breathing difficulties
- fever with enlarged lymph nodes
- but also severe life-threatening allergic conditions with cardiac and circulatory arrest.
Your doctor may decide to permanently discontinue treatment with Febuxostat Krka.
There have been rare reports of life-threatening skin rash ( Stevens-Johnson syndrome) associated with the use of febuxostat. These first appear as reddish dots or round spots, often with a blister in the middle, on the torso. It can also include sores in the mouth, throat, nose, genitals, and eye inflammation (red and swollen eyes). The rash can develop into blisters over large areas of skin detachment.
If you have had Stevens-Johnson syndrome after using febuxostat, you must never use Febuxostat Krka again. If you get a rash or these skin symptoms, contact your doctor immediately and tell them that you are taking this medicine.
If you have a gout attack right now (sudden onset of severe pain, tenderness, redness, heat, and swelling in a joint), wait until the gout attack has subsided before starting treatment with Febuxostat Krka for the first time.
In some people, gout attacks may flare up when they start taking certain medications that control the levels of uric acid. Not everyone gets attacks, but you can get an attack even if you take Febuxostat Krka, and especially during the first weeks or months of treatment. You must continue to take Febuxostat Krka even if you have an attack, as Febuxostat Krka still works by lowering the uric acid level. Over time, gout attacks will occur less frequently and be less painful if you continue to take Febuxostat Krka every day.
Your doctor will often prescribe other medicines, if needed, to help prevent or treat the symptoms of seizures (such as joint pain and swelling).
Treatment of patients with very high urate levels (eg patients undergoing chemotherapy for cancer) with uric acid lowering drugs may lead to an increase in urinary tract xanthine and possible stones, although this has not been observed in patients treated with febuxostat for tumor lysis syndrome.
Your doctor may ask you to provide blood tests to check that your liver is functioning normally.
