I shall try to answer, but what I am really hoping for is that a person who knows her/his stuff will step in, call me on my shallow perception, and offer an answer in depth. Here is my understanding: there are two types of mono-amine oxidase inhibitors (MOA-I), type A and type B. Type A interacts with the medications in the patent medicines such as Day-Quil and Sudafed. Type B does not. Eldepryl (Selegiline) is a selective MOA-I, type B only, when taken in small quantities. Ten mg per day is considered a small quantity. In larger quantities, it loses its selective property and becomes both A and B. Therefore, it may become dangerous, so the warning is necessary. Eldepryl and Demerol - still a potentially deadly no-no!!! So -FWIW...there's a bit more of the story.
