What is the appropriate dose of adult epinephrine for anaphylaxis?

• A. 0.1 to 0.2 mg
• B. 0.3 to 0.5 mg
• C. 0.5 to 1.0 mg
• D. 1.0 to 2.0 mg

Answer: (B)

The appropriate dose of adult epinephrine for anaphylaxis is indeed 0.3 to 0.5 mg. This dosing range is based on established guidelines for the management of anaphylaxis, where epinephrine is administered to combat severe allergic reactions that can lead to life-threatening situations, such as respiratory distress or cardiovascular collapse. Epinephrine acts as a bronchodilator, alleviating bronchospasm and also promoting vasoconstriction, which helps to restore blood pressure and improve circulation. The recommended dose typically involves administering 0.3 to 0.5 mg intramuscularly for adults, with the common practice being to use a 1:1000 concentration solution, which equates to a dose of 0.3 to 0.5 mL. This range ensures that patients receive an effective amount of the medication without the risks associated with higher doses, which might lead to increased side effects such as elevated heart rate or anxiety. In emergency settings, providers are often instructed to repeat doses as necessary depending on the severity of the reaction and the response to the initial administration, reinforcing the importance of careful dosing in acute scenarios like anaphylaxis.
