How often can you use Flonase nasal spray?

Medically reviewed by Leigh Ann Anderson, PharmD. Last updated on May 13, 2025.

Official Answer by Drugs.com

Flonase (fluticasone propionate) nasal spray is used once per day in both adults and children to provide 24-hour relief from allergy symptoms such as sneezing, runny nose, nasal congestion, and itchy, watery eyes. Nasal steroids like Flonase are most effective when used on a regular basis. It may take 3 to 4 days of regular use for the full effect during allergy season.

Do not use more than:

Studies in adults have shown that the administration of Flonase Allergy Relief once daily in the morning was as effective as a twice daily dosage regimen (one spray in each nostril twice a day), and either regimen was more effective than placebo.

Flonase dosing

Flonase Allergy Relief is used for seasonal and year-round allergies, including tree, grass and weed pollen, mold, dust mites, and pet dander. It helps with both indoor and outdoor allergies.

Adults and children 12 years of age and older

Children 4 to 11 years of age

The growth rate of some children may be slowed, so they should only use Flonase Allergy for the shortest amount of time possible to control symptoms. If your child needs Flonase Allergy for longer than two months per year, talk to your child's doctor for advice.

For children younger than 4 years of age, Children's Flonase Sensimist (fluticasone furoate) is available for children 2 to 11 years age and is given as 1 spray (27.5 mcg/spray) in each nostril once a day. Do not use more than one spray in each nostril per day. If your child still needs treatment after 2 months of use, contact their doctor.

Be sure to refer to the Over-the-Counter (OTC) Drug Facts Labeling, found in the Flonase package, for specific information.

Is over-the-counter Flonase the same as the prescription Flonase?

Yes, over-the-counter (OTC) Flonase Allergy Relief is exactly the same as prescription Flonase - it’s the same medicine, fluticasone propionate, at the same strength and dose. The prescription branded Flonase product is now discontinued in the U.S, but OTC Flonase products, generics, and store brands are available.

Should I keep taking my allergy pill with Flonase?

It depends. You usually don't need to keep taking an oral allergy pill if you are using Flonase Allergy at the right dose. But always follow your doctor's directions.

In studies, Flonase nasal spray at a dose of 200 mcg day used in combination with Zyrtec (cetirizine) allergy pill 10 mg daily was not shown to be more effective than using Flonase alone for nasal or eye allergy symptoms.
