Art, you said it better than I could.

Big ditto!

Even us allied health care professionals can get in trouble when we think we know as much as the doctor does.

I've been shocked at finding out that a few pharmacists self-treat with rx meds without a physician's prescription because they "know as much as he/she does." Not only is that ill-advised, it's also illegal.

One thing the practice of pharmacy has taught me is to respect medications. They are not candy, folks. Let the prescriber be the one to make the judgment call. (That's what he/she pays those exorbitant malpractice fees for!)
