Compare Flunisolide vs. Allegra

Head-to-head comparisons of medication uses, side effects, warnings, and more.

Key takeaways

Flunisolide and fexofenadine (Allegra) are both used to treat allergy symptoms, but they work in different ways and are used differently. Flunisolide is a corticosteroid nasal spray that you use directly in your nose to reduce inflammation and treat symptoms like congestion and sneezing. It requires a prescription and is used regularly for the best results. On the other hand, fexofenadine is an over-the-counter antihistamine taken orally to block histamine and relieve symptoms like sneezing, runny nose, and itchy eyes. Fexofenadine starts working in about 2 hours and can be taken as needed or regularly. Flunisolide is suitable for children 6 years and older, while fexofenadine can be used by children as young as 2 years, depending on the formulation. Flunisolide may cause nasal burning and stinging, while fexofenadine can cause headaches and dry mouth.
