Final answer:
Anaphylactic shock is a life-threatening medical emergency that cannot be relieved by antihistamines. It is a severe allergic reaction that requires prompt treatment with epinephrine.
Step-by-step explanation:
Anaphylactic shock is a life-threatening medical emergency that cannot be relieved by antihistamines. It is a severe allergic reaction that can occur in response to certain allergens, such as foods, medications, or insect stings.
During anaphylactic shock, the body releases a massive amount of histamines, which can cause respiratory distress and plummeting blood pressure. If not treated promptly with epinephrine, it can be fatal.
Epinephrine is a medication that helps counteract the effects of anaphylactic shock by raising blood pressure, relaxing bronchial smooth muscles, and reducing swelling.
