Allergens

Allergens are substances, often harmless in themselves, that can trigger an allergic reaction in susceptible individuals. These substances, which can be proteins, carbohydrates, or other compounds, provoke the immune system to overreact, leading to symptoms ranging from mild irritation to life-threatening anaphylaxis. Common allergens include pollen, dust mites, pet dander, certain foods (e.g., peanuts, shellfish), insect stings, and medications. Exposure to allergens can occur through inhalation, ingestion, injection, or skin contact, triggering the release of histamine and other inflammatory chemicals.
