Thats when the words "potentially fatal allergy" come in handy. (even if its an exageration) You should read my commentary on getting corn andgluten free tylenol.

I get a lot of "ask your dr" and then from my dr "Just call around."

I also once got a "How did you get this number?" (it was for medical professionals only, LOL, but hey...they got me connected to someone who could answer my question right away.)

I've heard that the new labelling laws do not extend to medicine. And that pharmaceutical companies get more leeway for proprietary formulas, but, I can't verify that.
