Has anyone here had allergic reactions to Concerta?

Added 12 Feb 2011:

The following side effects are listed under the drug Concerta extended release ON THIS SITE. No mention is made under the "side effects" for this medication that they may be caused by a possible allergy to polyethylene glycol and "inactive" ingredient in this product.

I think that the FDA should require labeling and package inserts CLEARLY state this possibility, and which ingredient(s) may be responsible, so that people having similar reactions can start to identify which ingredients they may be causing their reactions, and can proactively investigate these ingredients in the medicines they are taking. If they require cigarettes be labeled in this manner, they should require labeling cautions of other harmful ingredients that are ubiquitous (as polyethylene glycol is) in many medicines in the same way.

**** Please leave your comments on this labeling issue, since it has the potential to be a life threatening allergic response. I intend to follow up on these concerns of me and others with the FDA to see if I can get the labeling requirements for this ingredient changed for the good of all. ****
