<<Disclaimer: Verify this information before applying it to your situation.>> Hi I am on yet another medication that is not in any of my books and I always seem to get a quicker response here than on the phone. Since the doctors and pharmacists gave me such trouble last time and you all were so helpful I thought I could try here first. Here's the Q: Does anyone know if Sinuvent is gluten-free? I also remember someone saying Zithromax was GF but I am checking again to make sure. sinuvent seems to be made by We Pharm and Zithromax by Pfizer. thanks in advance. -Aimee
