Anaphylaxis

Anaphylaxis is a severe allergic reaction that occurs rapidly and can be life-threatening. It may be triggered by food, medications, or insect stings. If you suspect that you or someone else is experiencing anaphylaxis, dial 999 immediately. The symptoms typically manifest within minutes of exposure to an allergen, such as food, medicine, or an insect sting. You might also experience a rash that is swollen, raised, or itchy.
