Flonase Nasal Spray
Generic name: fluticasone nasal
Brand names: Flonase Sensimist, Flonase Allergy Relief, Children's Flonase Sensimist, Children's Flonase Allergy Relief
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.
