My mother takes waffarin and her doctor prescribed allopurinol. I am reading it interacts with blood thinners. Should she take it? She also takes colchicine, fluvastatin, furosemide, a 81 mg aspirin, klorcon, carbonyl iron, flonase, tramadole, multi vitamin and vitamin D. I feel like allopurinol may be a problem for her. She will be 84 in August.
