What is allergic rhinitis?

Rhinitis is a reaction that occurs in the nose when airborne irritants (allergens) trigger the release of histamine. Histamine causes itching, inflammation, and the production of fluid or mucous in the fragile linings of the nasal passages, sinuses, and eyelids.

What are the causes of allergic rhinitis?

The most common causes of allergic rhinitis are:

• Pollen (for example, tree, grass, or weed)
• dust mites
• Pattern
• cockroach excrement
• animal dander
• tobacco smoke

What are the symptoms of allergic rhinitis?

The following are the most common symptoms of allergic rhinitis. However, each child may experience symptoms differently. Symptoms may include:

• Sneeze

• Itchy nose, throat, eyes and ears
• nosebleeds
• clean drainage from the nose
• Children with perennial allergic rhinitis may also have:

• "Allergic salute." This is when a child rubs their hand up the bridge of their nose while sniffing. This can cause a line or wrinkle to form along the bridge of the nose.
