I use fluticasone proprionate nasal spray for winter allergy relief. This was recommended by my pharmacist but I was told to not use it for more than 3 days. The Drugs.com page for fluticasone proprionate says it is for non-allergic rhinitis, but the bottle says "allergy relief nasal spray", and to use daily (2-4 weeks) for maximum relief. Can someone please explain these discrepancies.
