A misguided reaction to foreign substances by the immune system, the body system of defense against foreign invaders, particularly pathogens (the agents of infection). The allergic reaction is misguided in that these foreign substances are usually harmless. The substances that trigger allergy are called allergen. Examples include pollens, dust mite, molds, danders, and certain foods.

Treatment varies with the severity and type of allergy symptom. The first course of action is to avoid the allergen if possible. Medications such as antihistamines are then usually prescribed to relieve the allergic symptoms.
