Medication Safety Tips

What Information is in a Prescription?

It is a good idea to make sure that you can read and understand what is written on your prescription before you leave your appointment. You should know which medicine you are being prescribed and how you are supposed to take it. Think of it as a double check before you get to your pharmacy.

Below is an example of a prescription. In Canada prescriptions can come in different formats (including electronic printouts) but they should all include similar information.

These are some commonly used Latin abbreviations that you may find on a prescription:

BID - twice a day
TID - three times a day
QID - four times a day
HS - at bedtime
Q4H - every 4 hours

Q12H - every 12 hours
QAM - every morning
PO - by mouth
PRN - as needed
UD - as directed

SL - under the tongue
ung - ointment
ac - before meals
pc - after meals
STAT - right away
