Verified step by step guidance1
Understand the condition: Anaphylaxis is a severe, potentially life-threatening allergic reaction that can occur rapidly. It requires immediate medical attention.
Identify the symptoms: Common symptoms of anaphylaxis include difficulty breathing, swelling, hives, a drop in blood pressure, and a rapid, weak pulse.
Recognize the first-line treatment: The primary drug used to treat anaphylaxis is epinephrine. It works quickly to improve breathing, stimulate the heart, and reduce swelling and hives.
Consider the mechanism of action: Epinephrine is a sympathomimetic drug that acts on alpha and beta-adrenergic receptors, leading to vasoconstriction, bronchodilation, and increased cardiac output.
Note the administration route: Epinephrine is typically administered via an intramuscular injection, often using an auto-injector (e.g., EpiPen), for rapid absorption and effect.
