Can Allopurinol Cause Kidney Damage?
Should not cause kidney problem
allopurinol is a commonly used drug for gout. the side effects are mostly skin reactions. it can cause interstitial nephritis in the kidney. though it is not common.
the dosage of allupurinol is dependent on the kidney functions. in normal functions you can easily take upto 300 mg per day . but in renal failure we do not use more than 100 mg.
febuxostat is another medicine for uric acid with even less side effects.
overall i dont think you need to worry. you can simply continue 100 mg per day.
