Hi, I had gone through your question and understand your concerns. here the problem with diclofenac you should be aware is that the major side effects are kidney failure, gastric perforation or gastritis, so it should be taken until unless it is necessary only. but you didnt mention in your question that for which problem you are on diclofenac. so i suggest to use tab ultracet, which has opiod content which acts centrally to decrease the pain rather than locally and causing side effects like diclo.
