Flonase is used in adults 18 and older to relieve symptoms associated with allergic rhinitis caused by pollen and other allergens present in the air, such as allergy to pets, dust mites and fungal spores. It relieves symptoms such as sneezing, nasal dripping, itching or nasal congestion, itching and tearing of eyes, up to 24 hours.
It may take 3 or 4 days for the highest level of protection to be achieved. It is therefore important to continue regular use to achieve maximum therapeutic benefit.
You should see a doctor if it gets worse or if it does not improve after 7 days.
