What is Flonase?

Flonase is a nasal spray containing fluticasone propionate. Fluticasone propionate is a corticosteroid that reduces inflammation in the lining of the nose.

Flonase Nasal Spray is used to treat nasal congestion, sneezing, runny nose, and itchy or watery eyes caused by seasonal or year-round allergies.

Flonase Allergy Relief is for use in adults and children who are at least 4 years old and is available without a prescription. Children's Flonase Allergy Relief contains the same medicine and is also for ages 4 and older.

Flonase Sensimist contains fluticasone furoate rather than fluticasone propionate and is approved for use in adults and children 2 years of age and older. Children's Flonase Sensimist is also for ages 2 and older. In Flonase Sensimist labeling, relief of itchy, watery eyes applies to ages 12 and older.

The brand-name prescription version of Flonase nasal spray has been discontinued in the United States. Generic fluticasone propionate nasal spray is still available by prescription, and over-the-counter Flonase products and store brands remain on the market.

Some products sold under the Flonase brand name are not nasal sprays and do not contain fluticasone. Flonase Headache & Allergy Relief caplets contain acetaminophen, chlorpheniramine, and phenylephrine, and Flonase Nighttime Allergy Relief tablets contain triprolidine. Check the active ingredients on the carton before use.

How should I use Flonase Nasal Spray?

Use Flonase exactly as directed on the label, or as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets.

Do not share this medicine with another person, even if they have the same symptoms you have. Sharing a bottle can spread germs.

Your dose will depend on the fluticasone brand or strength you use, and your dose may change once your symptoms improve. Follow all dosing instructions very carefully.

  • A child using the nasal spray should be supervised by an adult.

Read and carefully follow any Instructions for Use provided with your medicine. Ask your doctor or pharmacist if you do not understand these instructions.

Shake the bottle before each use. Flonase Allergy Relief should be shaken gently, and Flonase Sensimist should be shaken vigorously.

Use this product only once a day and do not use more than directed. Avoid getting the spray in your eyes or mouth.

If you switched to fluticasone from another steroid medicine, you should not stop using it suddenly. Follow your doctor's instructions about tapering your dose.

Storage differs between products. Store Flonase Allergy Relief and Children's Flonase Allergy Relief between 4°C and 30°C (39°F and 86°F). Store Flonase Sensimist between 15°C and 30°C (59°F and 86°F), and do not refrigerate or freeze it.

Throw the bottle away once you have used the number of sprays stated on the carton, even if there is still liquid in the bottle. The correct amount of medicine in each spray cannot be assured after the labeled number of sprays has been used. Bottle sizes vary between products and pack sizes, ranging from 30 to 144 metered sprays.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.

An overdose of Flonase is not expected to produce life-threatening symptoms. Using more than the recommended dose, or using it for longer than directed, may increase the chance of corticosteroid-related side effects such as cataracts or glaucoma, adrenal gland problems, an increased risk of infection, sores inside the nose, or slower growth in children.

Avoid getting the spray in your eyes or mouth. If this does happen, rinse with water.

Avoid being near people who are sick or have infections. Call your doctor for preventive treatment if you are exposed to chickenpox or measles.

What other drugs will affect Flonase?

Tell your doctor or pharmacist about all your other medicines, especially:

  • an antifungal medicine, such as ketoconazole tablets;
  • an antiviral medicine to treat hepatitis C or HIV/AIDS, such as ritonavir; or
  • another steroid medicine for asthma, allergies or skin rash.
