An itchy nose is usually caused by allergic rhinitis, which results from inhaling a substance that triggers an allergic reaction. Allergic rhinitis usually develops by age 10. Consult with your child's doctor or an allergist to determine the specific trigger of your child's itchy nose and develop a treatment plan.
Identification
An itchy nose is a common symptom of allergic rhinitis. Other symptoms include a runny nose, congestion and an itchy throat. Your child will probably sneeze frequently. Your child may appear to have a common cold, but will generally feel healthy and not have a fever. Dark circles may be present under your child's eyes.
Cause
Allergies are caused by your immune system's overreaction to a substance that is harmless to most people. The body creates antibodies called immunoglobulin E, which cause a chemical reaction that triggers an allergic reaction. The most common airborne allergens that cause an itchy nose are pollen, mold, animal dander and dust. Pollen is a seasonal allergy that most commonly occurs in the spring, summer and fall. Mold allergies are most noticeable during humid and rainy weather. Mold often grows in rooms where humidity is high, such as bathrooms and basements. Dust and dust mites can be found anywhere. Dust mites live on dead skin cells. If dust mites bother your child's allergies, the itchy nose is probably most bothersome at night when your child is trying to sleep.
Treatment
Once your child has an allergy, he will most likely always be allergic to the substance triggering the systems. Consult with your pediatrician for the best treatment method and before treating your child at home. Antihistamines are frequently used to treat allergic rhinitis and stop or reduce the itchiness of the sinuses. Inhaled corticosteroids or nasal sprays are also used for treatment. If the allergen is hard for your child to avoid, regular injections of the allergen may be given for several months to several years so your child's body gets used to the allergen and no longer has an allergic reaction. Have your child use a saltwater nasal spray to cleanse the sinuses. A steam shower also helps cleanse and loosen mucus so your child can blow allergens out of the sinuses.
Prevention
The best way to prevent an itchy nose is for your child to avoid the allergen. If the allergen cannot be easily avoided, ensure your child takes antihistamines daily with your doctor's approval. If pollen counts are high, keep windows closed and do not place fans in windows. Wash pets frequently and do not allow pets to sleep in your child's room. Keep a dehumidifier in your home to reduce mold and dust. Thoroughly clean your home regularly with diluted bleach and vacuum with a machine that has a high-efficiency particulate air filter. Cover your mattresses with plastic covers and wash your bedding weekly in hot water. Avoid outdoor activities on windy days when pollen is being blown around in the air.
