# Allergic Reactions

Allergic reactions occur when the immune system overreacts to a substance (allergen) that is normally harmless. Symptoms can range from mild (rashes, itching, and swelling) to severe (difficulty breathing, anaphylaxis). Common allergens include certain foods, insect stings, medications, pollen, pet dander, dust and latex.
