General Considerations

Inspect visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Do not use if the injection is pinkish or darker than slightly yellow or contains a precipitate. Discard any unused portion.

Diluted solution should be used immediately. Unused material should be discarded.

Recommended Dosage

Dosage should generally be started at the lowest recommended dose and increased gradually based on patient response.
Concentrations up to 10 times greater have been used when limitation of volume is essential.
Rates over 30 mcg per minute have been used in advanced stages of shock. Adjust the rate of infusion based on heart rate, central venous pressure, systemic blood pressure, and urine flow. If the heart rate exceeds 110 beats per minute, consider decreasing or temporarily discontinuing the infusion.
