question: Hi, My name is Vinood, 40 years age. The past three days I am using colchicine 0.5 bis. but have still some pain in my foot.  Also i use captopril 25mg for hypertension.   Can i use diclofenac 50 mg to ease the pain faster? Also i have been prescribed allopurinol 300mg. this i should use when the pain is over and then stop with colchicine.  Can i use all these drugs concomittant? Does the allopurinol have interaction with captopril?  regards, Vinood
