Sir I am taking anti tuberculosis medicines which have increased uric acid level to 10. Which is causing severe pain in my joints. When I consulted doctor handling my tuberculosis case she advised me to take febutaz 40 mg medicine to reduce uric acid level. But after 10 days of treatment I have got no relief. Should I eat febutaz of 80 mg now or to change the medicine? Doctor has advised me to take 40 mg capsule.
