Dave, note that I said MOST - Not ALL! There are exceptions to every rule. Having spent 15 years working in the field of medicine, I saw lots of things the average person never, or rarely sees. And, despite many of the more important cells in my aging brain being a bit frazzled, I still can remember most of the pharmacology information I learned way back then. Not much has really changed when it comes to allergic reactions to certain medications.
