There is no such list is why you can't find it. The problem is that the chemical makeup of the various sulfonomides is not all the same. (there are vaious search engines that will give you the chemical diagram of sulfa drugs and the various other substances so that you cna see the differences) And so people who are allergic to one composition may not be allergic - or as allergic - to others. As a result, you will see that any drugs which are related at all to sulfa drugs will ahve the caution on the label or in the text information. I am allergic to sulfa drugs but the allergy is digestive/gastric in nature not hives or some other reaction. So the issue with me is do I need this specific drug enough to warrant seeing if I have a reaction? And if I do, is it something I can wait out and possibly get over or so strong that I can't continue with the medication? For example, my internist really wanted me on Diovan HCT. It has the sulfa drug caution. We discussed it and I decided to try it. Sure enough, a good bit of gastric distress but I kept at it and in time it went away. Now I have no problem with that particular drug. So that's how I handle the drug issue.
With fooRAB, it's not so bad but I do sometimes have gastric distress that's not traceable to anything else and sometimes get the odd welt on my face that I am certain is related to this. However, neither has been severe enough to make me search out the exact culprit and eliminate it.
Bottom line is you just have to read labels. And even then you might not catch all of them.
