Epinephrine Drip Rate Calculator

Fast epinephrine infusion math for cardiogenic shock, anaphylaxis, and post-ROSC care. Supports mcg/kg/min and mcg/min orders with any concentration.

Epinephrine dose ranges

IndicationTypical dose range
Cardiogenic shock0.01–0.5 mcg/kg/min
Anaphylaxis infusion1–10 mcg/min
Post-ROSC vasopressor0.05–0.5 mcg/kg/min
Low-dose inotrope0.01–0.05 mcg/kg/min

Ranges are approximate. Titrate to clinical response per your protocol.

Formula

mL/hr = (mcg/kg/min × kg × 60) ÷ mcg/mL

Standard mix: 4 mg in 250 mL D5W = 16 mcg/mL. For fixed-rate (mcg/min): mL/hr = (mcg/min × 60) ÷ mcg/mL.

Frequently asked questions

What's the standard epinephrine concentration for infusion?

4 mg in 250 mL D5W is common (16 mcg/mL). Some institutions use 1 mg in 250 mL (4 mcg/mL) for lower-dose infusions in anaphylaxis.

Can I calculate epinephrine in mcg/min instead of mcg/kg/min?

Yes — select the mcg/min mode in the calculator. The formula drops the weight term and computes mL/hr from mcg/min directly.

Is this safe to use for pediatric patients?

Enter the patient's actual weight in kg for accurate weight-based dosing. Pediatric concentrations vary significantly — always confirm with your pharmacy and institutional protocols.
