Allergic Reaction Definition and Symptoms
Allergic reactions are an immune response or reaction to a usually unharmful substance. The most common allergens are drugs, mold, pet dander, and pollen. Symptoms of an allergic reaction depend on the type of allergen that causes the reaction: allergens that you breathe can cause stuffy nose, itchy throat, cough, and wheezing. Allergens which touch the skin can cause rash, itching, blisters, or skin peeling. Drug allergies can cause whole body symptoms.
