What are FLONASE® products and how do they work?

Close
Open

FLONASE® products are allergy relief medicines that work right in your nose to help block your allergic reaction at the source to relieve the symptoms that make you uncomfortable.

FLONASE® products act on multiple inflammatory substances, including histamine, prostaglandins, cytokines, tryptases, chemokines and leukotrienes. Most common OTC allergy pills act only on histamine.*

Because of the way it works, it may take several days for FLONASE® products to reach maximum effect. That’s why it’s best to use FLONASE® products once a day, every day, during allergy season. FLONASE® products not only relieve sneezing, itchy nose, runny nose and itchy, watery eyes**, but also relieve nasal congestion.

What happens when you have allergies?

Close
Open

Allergies start when allergens like pollen, pet dander, dust, or mold enter your body. 

When this happens, your body’s natural response is to release multiple inflammatory substances, in order to get rid of the allergens. But it’s these inflammatory substances that cause your allergy symptoms.

Won’t I waste product by priming?

And remember, always point the spray bottle away from your face when priming.
