Medicine Overview of Febus 80mg Tablet

Introduction

Febus 80 is a medicine used to treat and prevent gout. Gout happens when there is too much uric acid in your body and it forms into crystals which can appear around your joints leading to painful and swollen joints. This medicine helps to keep uric acid levels low. Febus 80 can be taken with or without food. You should keep taking it as recommended by your doctor even when you are not having a gout attack. If you stop, your symptoms may get worse because of the formation of more crystals in your joints. You can help yourself by making some changes to your diet (eg. avoiding alcohol and non-vegetarian foods) and drinking plenty of fluids. Some of the common side effects of this medicine are headache, diarrhea, nausea, skin rash and a temporary increase in gout symptoms (rapid onset of severe pain, warmth, and redness in the joint). However, do not stop taking it. Your doctor may advise you some painkillers and additional medicines to help you reduce or prevent these symptoms. Rarely, some people may get a severe allergic reaction (difficulty in breathing, hives, swelling of face and throat, weakness) which may need urgent medical attention. Also, tell your doctor right away if you get any symptoms of liver disease like persistent nausea, dark urine or yellowing of the eyes or skin. Before taking this medicine, let your doctor know if you have any heart problems, stroke, thyroid problems, or kidney or liver problems. If you are pregnant or breastfeeding, this medicine is best avoided. Check with your doctor. You will need regular blood tests while taking this medicine to check that your liver is working properly.

Precaution

Evaluate risks and benefits when prescribing febuxostat or continuing treatment.
