The medication order has all the required components (drug
name, dose, route, and frequency of administration) for a drug
order. “PO” is an appropriate abbreviation; 40 mg is written
correctly with a space between the dose and the unit of
measurement. Tall man lettering is used to distinguish the drug
from another drug
with a similar name.

drug label?
A It is primarily is used to identify the safe dose for the
patient.

and does not provide information to reduce or decrease side
effects.
