Febuxostat is used to lower uric acid levels in people with gout. Febuxostat works by reducing the amount of uric acid made by the body. An increased uric acid level can cause gout.
Because of the risk of very serious heart-related problems and stroke with febuxostat (see also Warning section), febuxostat should be used only after treatment with a medication called allopurinol did not work to lower your uric acid level, caused serious side effects, or is not recommended by your doctor. Febuxostat should be used only if you have symptoms caused by a high blood uric acid level.
Nausea may occur. If this effect lasts or gets worse, tell your doctor or pharmacist promptly.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
Febuxostat may rarely cause serious (possibly fatal) liver disease. It may also cause an increase in liver enzymes. Your doctor will order blood tests to measure these enzymes. Keep all medical/lab appointments. Tell your doctor right away if you develop symptoms of liver disease, including nausea that doesnt stop, stomach/abdominal pain, dark urine, yellowing eyes/skin.
Tell your doctor right away if you have any serious side effects, including: pink/bloody urine, painful urination.
Febuxostat may cause a rash that could be a sign of a severe reaction. Get medical help right away if you develop any rash.
A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: fever, swollen lymph nodes, rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
