Did you ever look at a prescription after leaving the doctors office? Then think what the heck does this say. I don’t understand a word he/she wrote, how’s the pharmacist going to understand this?
Yet, when you present the script they don’t blink an eye and fill it no questions asked.
So, a quick lesson in understanding a prescription. First, most doctors write in Latin, there fore us lay people don’t have a clue what the doctor wrote.
So, for example the doctor gives you a script for metformin a popular diabetes medication, and it looks somerthng like this
Rx: metformin oral tablet 500mg
Not so bad.
Sig: T PO BID, PRN
Well the T, firstly will have a dot above it. This in English means one, then the po means by mouth and the bid means twice a day, the prn simply means or as needed. By the way the sig means instructions. So why couldn’t they just write one tablet twice a day. Beats me.
It certainly would make more sense at least to us lay people.
Some more abbreviations :
Qid 4 times a day
TID Three times a day
Qpm At bedtime
Qam In the morning
That’s today’s lesson in doctor speak. They went to school for eight years for that!!!!!
