No that is an overdose.
To come to this conclusion this is the formular:
Convert teh 50 mcg to mg (3 decimal places to the left)= .05 mg/kg
multiply: 3.3kg X 0.05 mg = the appropriate dose

1 milligram = 1000 micrograms..but...
where did you get that recommended dosage? My book sez the recommended dosage is 0.1 - 0.2mg/kg, so the dosage range would calculate to 0.33-0.66mg (0.1-0.2mg x 3.3 kg) 0.5 mg would be right in the middle of that range, looks like the correct dosage.
hope I didnt confuse the issue
PS 0.5mg = 500 mcg
thank you all for the replies....that helped me

our standard dose is 0.1 - 0.2 mg/kg/dose q2h prn for intubated patients. our extubated and spontaneously breathing patients get half that... or 0.05 - 0.1 mg/kg/per dose q4h prn. so i guess the op and nj1grlcrus are both "right".
