Before you can understand how FLONASE works, it’s important to understand what’s going on in your nose.


Allergy Inflammatory Process

  • Every time you’re exposed to one of your nasal allergy triggers (like animal dander, dust mites, or pollen), your body responds by producing inflammatory substances.

  • These inflammatory substances affect the lining of your nose, and then trigger annoying symptoms like nasal congestion, sneezing, and itchy, runny nose.

  • It’s a cycle, or what’s called an inflammatory process—you’re exposed to allergens, your body responds by producing inflammatory substances, and the result can be annoying nasal symptoms.

FLONASE reduces inflammatory reactions that may lead to nasal symptoms such as congestion, sneezing, and itchy, runny nose.

As with many medications, exactly how FLONASE works isn’t entirely understood.


How FLONASE Reduces Inflammation

FLONASE belongs to a class of medications called intranasal corticosteroids that reduce inflammation, therefore, reducing the nasal airway's response to allergens and irritants in the air.


Intranasal Corticosteroid Basics

  • Intranasal corticosteroids are similar to cortisol, which is produced by your own body.
  • Cortisol is the body's way of dealing with inflammation, stress, injury, and infection.
  •  

    Not All Steroids Are Created Equal

  • Anabolic steroids are very different from intranasal corticosteroids.
  • Anabolic steroids are sometimes used inappropriately to increase muscle mass and improve performance.
  • They are synthetic substances related to male sex hormones and if inappropriately used, may produce dangerous, even fatal, side effects.
