Comments from related studies:
From this study (1 day ago):
I have been diagnosed with IBS, but I have reason to believe that maybe taking Allopurinol for the last 8 years for Gout may have some effect on my condition. I understand that 300 mg may be too strong for me. My last uric acid level was 3.1 which is in the normal range...should I reduce my amount of the medication to 1/2? Also, I have not been taking the medication after a meal, but at night before I go to bed. Any advice.
