General
- Type: Vasopressors
- Dosage Forms:
- Concentration
- Amount of solution in mL used to dilute 1,000mg of epinephrine
- eg 1:10,000 = 1,000mg/10,000mL = 0.1mg/mL
- Common Trade Names: Adrenaline
Adult Dosing
Anaphylaxis
0.3-0.5mg of 1:1,000 IM
- Consider glucagon 1-5mg IV if pt on B-blockers and not responding to epi
Anaphylactic shock
0.1mg of 1:10,000 slow IV during 5 min, can start infusion of 1-4 mcg/min
Cardiac Arrest
1mg of 1:10,000 IVP
Pediatric Dosing
See critical care quick reference for drug doses by weight.

- Pregnancy Rating:
- Lactation:
- Renal Dosing
- Adult
- Pediatric
- Hepatic Dosing
- Adult

Dosing
- Dose-dependent effects:
- 1-10 mcg/min - increase HR and SV
- 10-20 mcg/min - increase SVR
Rate of Titration
- Q2-5 min
Adverse Effects
- Tachyarrhythmias
- Myocardial ischemia
- ↑Serum lactate
- Splanchnic ischemia
Notes
- ↑lactate occurs primarily from ↑glycolysis/glycogenolysis within skeletal muscles not tissue hypoperfusion
- Use with caution in pts with CAD
- However clinical trials have not demonstrated worsened outcomes
