<<Disclaimer: Verify this information before applying it to your situation.>> Hey all I'm at a loss. Prior to my diagnosis of CD/DH i used Claritin D for my allergies. I switched to Allegra, and began to react. Using process of elimination, It appears to be casein/lactose?? I have to finish the Asthma testing before they'll send me to an allergist, so i have no idea how to go about this other than by eliminating it and then eating some in a month or so. But I can't figure out how to eliminate it. You see: Claritin D's manufacturer won't guarantee that the product is gluten free. Allegra and Allegra D contain lactose Zyrtec contains lactose So. If anybody out there is gfcf and has allergies, could you tell me what you are taking? Thanks.
