Allergies are reactions by your immune system to substances that are typically harmless but that your body mistakes as a threat. You might experience symptoms like sneezing, itching, rashes, or difficulty breathing when exposed to allergens. Allergy treatment varies depending on the allergen and severity of symptoms and can include medication, immunotherapy, and avoiding triggers. Identifying allergens, taking preventive measures, and carrying an emergency epinephrine shot with you at all times are crucial for managing allergies and avoiding potentially dangerous allergic reactions.[1]
