👉 Anaphylaxis is a severe allergic reaction that occurs when your immune system overreacts to harmless substances, such as pollen or dust. It can cause symptoms like hives, swelling of the mouth and throat, difficulty breathing, wheezing, and even shock. Symptoms can vary from person to person, but they typically start after exposure to the allergen. If you are experiencing anaphylaxis, seek medical help immediately by calling emergency services or taking a medicine prescribed by your doctor.
