Maximum Epinephrine Dosage in Cardiac Arrest

Standard Dosing Recommendations

• The American Heart Association (AHA) guidelines recommend administering 1 mg of IV/IO epinephrine every 3 to 5 minutes during adult cardiac arrest (Class IIb, LOE B-R) 1, 2, 3
• This dosing regimen is supported by evidence showing improved return of spontaneous circulation (ROSC) and survival to hospital admission compared to placebo 4
• There is no officially defined maximum cumulative dose or number of doses in the current guidelines 1, 2

High-Dose vs. Standard-Dose Epinephrine

• High-dose epinephrine (0.1 to 0.2 mg/kg) is not recommended for routine use in cardiac arrest 5
• While high-dose epinephrine may increase ROSC rates, studies have not demonstrated any benefit for survival to hospital discharge 6
• The adverse effects of higher doses in the post-arrest period may negate potential advantages during the arrest 3

Special Considerations

• High-dose epinephrine may be considered in exceptional circumstances such as β-blocker overdose 7
• High-dose epinephrine may be considered in exceptional circumstances such as calcium channel blocker overdose 3
• High-dose epinephrine may be considered when titrated to real-time physiologically monitored parameters 3

Pediatric Dosing

• For pediatric cardiac arrest, the recommended dose is 0.01 mg/kg (0.1 mL/kg of 1:10,000 concentration), with a maximum single dose of 1 mg 8, 7
• This dose should be repeated every 3-5 minutes 8
• High-dose epinephrine is not recommended for routine use in pediatric patients 7

Common Pitfalls

• Using high-dose epinephrine routinely without specific indications 3
• Failing to recognize when epinephrine may be harmful, such as in cardiac arrest associated with sympathomimetic drug overdose 9
