<<Disclaimer: Verify this information before applying it to your situation.>> Researching Pain killers can be a real pain! 5/17/95 I spoke with Donna Marie Valentine R.N. @ Whitehall Laboratories (maker of Advil, 800-322-3129) medical division. Ms. Valentine said " Advil is not made consistently from one source. The COMPANY CAN NOT VERIFY THAT ADVIL IS GLUTEN FREE. Because they use various vendors, some who use wheat derivative binders. The good news is that ORUDIS ( a Ketoprofen, similar to ibuprofen) IS VERIFIABLY GLUTEN FREE, the binder is corn based, according to Ms. Valentine. ***It is becoming clear that some action needs to be taken in regards to the FDA requiring clear labeling for GF. I dream that someday, there will be a GF identification marker on all products & pharmaceuticals, similar to that of Kosher labeling.
