Ideally by avoidance
Allergens include dust mites, pet dander
, molds, and seasonal pollens.
Avoidance is the best strategy, but is not always practical (ex. Outdoor pollens). Medicines can be helpful including nasal steroid sprays and oral antihistamines. Allergy shots help induce tolerance to allergens in appropriate patients. An allergist can help diagnose and treat your child's allergies.
