Zenfab 40mg Tablet 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 that can appear around your joints leading to painful and swollen joints. This medicine helps to keep uric acid levels low.
Zenfab 40mg Tablet 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 liver function abnormalities, nausea, joint pain, and rashes. You may experience a temporary increase in the gout symptoms (rapid onset of severe pain, warmth, and redness in the joint) when you first start taking the medicine. However, do not stop taking the medicine. Your doctor may suggest some painkillers and additional medicines to help reduce or prevent these symptoms. 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.
