The word "anaphylactic" is spelled using the IPA phonetic transcription as [ænəfaɪˈlæktɪk]. It starts with the vowel sound of "æ" (as in "cat"), followed by the "n" consonant sound, and then the vowel sound of "ə" (as in "sofa"). Next comes the "f" and "aɪ" sounds, followed by the "l" and "æ" sounds, and ending with the "k" and "tɪk" sounds. This complex spelling reflects the medical term for a severe allergic reaction that can lead to shock and even death.
The term "anaphylactic" refers to a severe and potentially life-threatening allergic reaction that occurs rapidly and suddenly. It is characterized by an exaggerated immune response to a specific allergen, such as a drug, food, venom, or certain chemicals. The immune system of a highly sensitive individual overreacts to the substance, causing the release of large amounts of histamine and other chemicals into the bloodstream. This sudden release of substances triggers a cascade of physiological responses throughout the body.
Anaphylactic reactions can occur within minutes or even seconds after exposure to the allergen, and they typically involve multiple organ systems. Symptoms can range from mild to severe and may include itching, hives, swelling of the face or throat, difficulty breathing, wheezing, coughing, chest tightness, rapid or weak pulse, dizziness, fainting, nausea, vomiting, abdominal pain, and sometimes even loss of consciousness.
Immediate treatment for anaphylaxis is crucial to prevent fatalities. The initial step often involves administering epinephrine (adrenaline) via an auto-injector to counteract the allergic response. Additional measures may involve providing oxygen, intravenous fluids, antihistamines, and corticosteroids. Emergency medical attention is always necessary, even if the symptoms improve after using an epinephrine auto-injector.
Anaphylactic reactions can be unpredictable and pose serious risks. Therefore, individuals with known allergies or those who have experienced anaphylactic reactions in the past are advised to carry an epinephrine auto-injector and inform their healthcare providers about their condition.

The word "anaphylactic" comes from the combination of two Greek roots: "ana", meaning "against" or "opposite", and "phylaxis", meaning "protection" or "guarding". The term was first introduced by the father of modern allergy, Charles Richet, in 1902 to describe a severe allergic reaction that occurs when the body's immune system overreacts to an allergen, such as food, medication, or insect stings. The word "anaphylactic" is used to characterize this phenomenon where the body's immune system produces an intense response against a harmless substance, which it wrongly recognizes as a threat.
