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:
- Runny nose
- Itchy nose, throat, eyes, and ears
- Clear drainage from the nose
- Children with perennial allergic rhinitis may also have the following:
- Recurrent ear infections
- Breathing through the mouth
- Poor performance in school
- "Allergic salute." This is when a child rubs his or her hand upward across the bridge of the nose while sniffing. This may cause a line or crease to form across the bridge of the nose.
The symptoms of allergic rhinitis may resemble other conditions or medical problems. Always consult your child's health care provider for a diagnosis.

Preventive measures for avoiding allergic rhinitis include:
- Environmental controls, such as air conditioning, during pollen season

The link between allergic rhinitis and asthma
Controlling asthma may mean controlling allergic rhinitis in some patients, according to allergy and asthma experts. Allergic rhinitis is a common problem that may be associated with asthma.
Guidelines from the World Health Organization recognize the link between allergic rhinitis and asthma. Although the link is not fully understood, one theory asserts that rhinitis makes it difficult to breathe through the nose, which hampers the normal function of the nose. Breathing through the mouth does not warm the air, or filter or humidify it before it enters the lungs, which can make asthma worse.
