What is allergic rhinitis?

Allergic rhinitis, also known as hay fever, is a condition in which inflammation occurs inside the nose. The inflammation is caused by an allergen (a substance that causes an allergic reaction). The most common allergens that cause allergic rhinitis are dust mites, pollen, pet dander, or mold.

When you breathe in an allergen (via mouth or nose), your body reacts to it by releasing a natural chemical called histamine, which causes mucous membranes in the throat, eyes, and nose to become inflamed and itchy to remove the allergen from the body. 

Allergic rhinitis is not the same as infectious rhinitis (common cold). Also, allergic rhinitis is not contagious. 

Causes of allergic rhinitis

 Some of the common allergens include: 

  • Pollen 
  • Dust mites 
  • Animal dander 
  • Molds 
  • Cat saliva 
  • Work-related allergens (wood dust, latex, or flour dust)

How cetirizine helps to control the effect of allergic rhinitis, use, and dosage

Cetirizine belongs to the antihistaminic class of medication. This class of drugs works by blocking the action of the natural chemical histamine.
