Order is alprazolam 250 mcg po tid.
Supply is Alprazolam 1 mg/ml.
How many ml will you administer?
Desired dose=250mcg
Available dose =1mg/ml
first convert micrograms to milligrams
1mg=1000mcg
So, 250÷1000=0.25
250mcg=0.25mg
So we have to find out how many milliliters in 0.25mg of drug
That is,
1mg/1ml=0.25mg/x ml
=0.25ml
We should administer 0.25ml of alprazolam
