About Viostat 40 Tablet

Viostat 40 Tablet is used to prevent severe gout attacks or flares. Gout is a chronic condition caused by the deposition of uric acid crystals in the joints. It is characterised by intense pain and swelling at the affected joints.

Viostat 40 Tablet contains febuxostat, which works by inhibiting the enzyme xanthine oxidase (an enzyme that helps your body produce uric acid), thereby reducing the level of uric acid in your body. Thus, it reduces the inflammation caused by uric acid crystals in affected joints.

The common side effects of Viostat 40 Tablet include nausea, rash, dizziness, diarrhoea, pain, and localised swelling due to fluid retention in tissues (oedema). Most of these side effects of Viostat 40 Tablet do not require medical attention and typically resolve on their own over time. However, if the side effects persist, contact your doctor.

Take this medication by mouth with or without food as directed by your doctor. The dosage is based on your medical condition and response to treatment.

Diet & Lifestyle Advise

  • Include more glucosamine, chondroitin sulfate, vitamin D, and calcium-enriched supplements. Turmeric and fish can also help reduce inflammation in the tissue.
  • Please avoid heavy exercise, as it may exacerbate your joint pain and arthritis. Instead, you can engage in low-impact aerobic movements, such as walking on a treadmill or swimming. You can also strengthen your muscles by lifting light weights.
  • Your sitting posture is important, especially when you have pain and inflammation. Try to sit as little as possible and only for a short duration of time. Long-term immobility is harmful in conditions like arthritis. Use a back support, such as a rolled-up towel, to minimise pain at the curve of your spine. Keep your knees and hips at a right angle. You can also use a footrest if required.
  • Avoid a high purine-rich diet, including organ meats (kidneys, liver, and sweetbreads) and oily fish (sardines, anchovies, and herring).
  • Limit meat in favour of plant-based proteins, such as beans and legumes.
  • Eat complex carbohydrates, such as whole-grain bread, fruits, and vegetables, rather than sugary sweets and refined carbohydrates like white bread.
  • Avoid drinking beer and alcoholic beverages, and drink plenty of water or other nonalcoholic beverages.
