Key takeaways
Flonase (fluticasone) and flunisolide are both corticosteroid nasal sprays used to treat allergy symptoms like congestion, sneezing, and runny nose. Flonase is available both over-the-counter and by prescription, while flunisolide is only available with a prescription. Flonase can be used by people as young as 2 years old, whereas flunisolide is approved for use in individuals 6 years and older. Flonase comes in two formulations: Flonase Allergy Relief and Flonase Sensimist, with the latter being a gentler mist. Flunisolide, on the other hand, is only available in one formulation. Flonase typically requires once daily dosing, while flunisolide is usually taken twice daily. Both medications can cause side effects like nosebleeds and slowed growth in children, but flunisolide has a higher incidence of nasal burning and stinging.
