How Beconase Works and Why It Can Treat Nonallergic Nasal Allergies
Beconase Uses for Non-Allergic Nasal SymptomsSometimes, people have year-round nasal symptoms (such as nasal congestion, runny nose, or itchy nose) that are not caused by allergens. This is called non-allergic rhinitis or vasomotor rhinitis. It is caused by expansion (dilation) of the nasal blood vessels, which fills the nasal lining with fluid. Inflammation may also play a key role. Sometimes, certain problems (such as infections or exposure to irritants such as smoke) can cause or worsen non-allergic rhinitis.
Beconase AQ is approved to treat non-allergic rhinitis. Although it is not exactly clear how or why the drug works for non-allergic rhinitis, studies have shown that it is an effective treatment.
As mentioned, allergies occur when the body's immune system reacts to a normally harmless substance -- one that does not bother most people. These immune system reactions are known as inflammations and involve several different types of cells and several different chemicals in the body.
Beconase is a corticosteroid, or simply "steroid" for short. Steroids can have many different effects in the body, including anti-inflammatory effects. They decrease inflammation by limiting the body's ability to produce an immune system reaction. Steroids can be effective for treating conditions such as allergies. However, long-term use can cause bothersome and sometimes serious side effects, and this limits the usefulness of many steroids. Because Beconase is a nasal spray, its effects are generally limited to the nose. This helps prevent many of the long-term side effects of steroids.
It is not known exactly how Beconase works for non-allergic rhinitis.
Many cases of nasal polyps are related to chronic inflammation caused by nasal allergies. Beconase AQ works to treat nasal polyps by decreasing inflammation.
