<<Disclaimer: Verify this information before applying it to your situation.>> For all of you fellow allergy sufferers, there is relief. I just spoke with Patty Johnson at Hoechst Marion Roussel [(816) 966-5000], the drug company that makes Allegra and Allegra D. Both medications (12 hour pills) are "free from wheat, oats, rye, barley and spelt grains. They do contain corn starch." Since I haven't been able to get confirmation on the gf status on Claritin D (I've seen a lot of contradictory info), Allegra D is the next best choice for me. Not as powerful or quick acting as Claritin D, but it definitely helps when the pollen count goes up. KEEP IN MIND - THIS IS PRESCRIPTION MEDICATION - SO SPEAK TO YOUR DOCTOR FIRST. Everybody handles medication differently.
