How Does Intranasal Allergy Spray Work?

Intranasal allergy spray prevents congestion of the nose and sinuses associated with:

• Seasonal allergic rhinitis
• Perennial allergic rhinitis
• Vasomotor rhinitis

Allergic rhinitis is the irritation and inflammation of the membranes lining the nose triggered by an allergen. Inflammation is caused due to the activation of histamine by the immune system. In some people, the upper airway, which includes the nose, nasal cavity, and pharynx, may overreact to irritants leading to hyperactivity of the airways. 

Intranasal spray blocks the release of histamines and may reduce the hyperactivity of the airways.
