Fluticasone Propionate - Nose Spray in Gluten-Free Foods, Products, Shopping & Medications Posted February 11, 2011 · Report to Admin Hi Everyone - I am hoping someone can help me with a prescription Nose Spray question. I have been having stomach issues recently and I realized it started around the same time that I began using the new nose spray. I tried contacting the company but have not been able to reach anyone. The medication is generic for Flonase. Product Information: Fluticasone Propionate Manufacturer: Hi.Tech Pharmacal Please let me know if anyone has any information about this drug! Thank you in advance!
