<<Disclaimer: Verify this information before applying it to your situation.>> Hi all. Thanks so very much for all of your help with antibiotics for my sinus problem. Today I went to the doctor and he diagnosed me with a sinus infection, no surprise, and prescribed antibiotics as well as 2 nasal sprays. Suggestions I got from listmates were that the following antibiotics were gf: Zithromax, Cipro, Tequin, Cydamazine, and Biaxin. Most people suggested purchasing A Stokes Guide for Prescriptions, which I will do. Others suggested a salt water or saline nasal flush which I think is kind of gross. But it works I guess. The doc also gave me a sample of Nasonex and told me to buy Neo-Synephrine Mild Spray. ARE THESE GLUTEN FREE? The only questionable ingredient is citric acid. Does anyone know? I will call the company if no one knows offhand. Thanks so very very much!! Joanna
