Allergens are substances that are usually proteins or protein-carbohydrate compounds but sometimes are chemicals.
Environmental allergens have been identified and standard allergy testing and treatment is available for them. Knowing your specific triggers is vital to help you control your symptoms. It is possible to reduce symptoms by practicing certain avoidance measures and/or by medication. The common indoor allergens include dust mites, cat, dog, mice, cockroach and mold. Outdoor allergens include mold and pollens.
