Febuxostat can treat gout and is very effective for people with hyperuricemia who suffer from gout. Long-term use of febuxostat can cause side effects on the body, affecting kidney function, liver function, and in some people, nausea, vomiting, excessive stomach acid, mouth ulcers, gastroesophageal reflux, abdominal pain, bloating, and indigestion. In severe cases, this can lead to damage to the blood and lymphatic system, idiopathic thrombocytopenic purpura, anemia, and abnormal white blood cells. Fibrates should not be taken together with azathioprine, cholecalciferol, mercaptopurine, etc. The dosage should be strictly in accordance with medical advice, preferably not in large quantities for a long time, and the dosage needs to be reduced after the symptoms are relieved. To reduce the side effects, pay attention to the diet during the drug, eat less spicy and stimulating food, and drink more water, which can eliminate toxins from the body.
