From the Guidelines
Epinephrine is a life-saving medication used to treat severe allergic reactions, cardiac arrest, and certain types of shock, and its administration is crucial in emergency situations to prevent morbidity, mortality, and improve quality of life.
Definition and Use
Epinephrine, also known as adrenaline, is a hormone and medication that plays a critical role in treating anaphylaxis, a severe, potentially fatal systemic allergic reaction. According to the most recent and highest quality study 1, epinephrine is the primary medical therapy for anaphylaxis and must be administered promptly. The recommended dose is 0.01 mg/kg of 1 mg/mL (1:1000), up to 0.5 mg in adults and 0.3 mg in children and teenagers, administered intramuscularly into the vastus lateralis (antero-lateral thigh).
Administration and Dosage
The administration of epinephrine is critical in emergency situations, and the dosage should be adjusted according to the patient's weight and the severity of the reaction. As stated in the study 1, there are no absolute contraindications to the use of epinephrine for anaphylaxis, and additional doses of intramuscular epinephrine should be given every 5 to 15 minutes if anaphylaxis signs or symptoms persist.
Importance of Prompt Administration
Delayed use of epinephrine can be ineffective, and fatal outcomes are often associated with delay or lack of administration of epinephrine, as reported in the study 1. Therefore, it is essential to administer epinephrine promptly in emergency situations to prevent morbidity, mortality, and improve quality of life.
Education and Training
Patients and their caregivers should be educated about the signs and symptoms of anaphylaxis and trained on proper administration technique of epinephrine auto-injectors, such as EpiPen or Auvi-Q, as recommended in the study 1. This education and training are crucial in ensuring that patients receive timely and effective treatment in emergency situations.
Side Effects and Benefits
While epinephrine can cause side effects such as anxiety, tremors, palpitations, and increased blood pressure, these are generally outweighed by the life-saving benefits in emergency situations, as stated in the example answer. The benefits of epinephrine in treating anaphylaxis and other emergency situations far outweigh the potential risks, and its administration is critical in preventing morbidity, mortality, and improving quality of life.

Epinephrine, also known as adrenaline, is a sympathomimetic catecholamine that acts as a non-selective alpha- and beta-adrenergic agonist. It is a medication used to increase mean arterial blood pressure in adult patients with hypotension associated with septic shock, among other uses. 2 2 3
From the Research
Definition and Role of Epinephrine
- Epinephrine, also known as adrenaline, is a medication used to treat anaphylaxis, a severe and potentially life-threatening allergic reaction 4, 5, 6, 7, 8.
- It is considered the first-line treatment for anaphylaxis and is typically administered intramuscularly in the anterolateral thigh 4, 5, 6, 7.
Administration and Dosage
- The recommended adult dose of epinephrine is 0.3-0.5 mg, injected intramuscularly in the anterolateral aspect of the mid-thigh 5.
- For children, the dose is 0.01 mg/kg, given in the lateral thigh 6.
- Epinephrine autoinjectors are available in different doses, including 0.15 mg, 0.30 mg, and 0.50 mg, and are prescribed based on the patient's weight 7.
Importance of Prompt Administration
- Delayed administration of epinephrine can be fatal, and it is essential to administer it immediately after the onset of anaphylaxis symptoms 4, 5, 6, 8.
- Prompt administration of epinephrine can help prevent unnecessary increases in patient morbidity and mortality 4.
