English used in Prescription Writing

I have studied the apothecary system, and notice they use roman numerals on prescriptions to indicated the number of tablets or capsules in the signa, such as

iii po BID

Alos, some doctors do:

TTT po BID

(for three tablets twice a day by mouth)

But I notice most doctors, when they write a script and use "T" for tablet, but they also add a special symbol on top of the "T". Some doctors put a quotation mark on top of it:

"
T

While others use something like a grave accent:

`
T

Does anyone know what these mean? I've seen other strange symbols too.

Thanks!

Hi, Milena and everyone:

I am a nurisng instructor and would like to explain that what you think is the letter T with a dot over it is NOT the letter T. As you will see in the post where someone has actually shown a hand-written prescription, the so-called T is actually a Roman number with a bar on top of it and then the dots are above each bar. You can read this tablets but i

Just wanted to be clear; among the U.S. medical community, that Rx specifically reads "tablets."

A physician indicating capsules, for example, would have written "cap." For some medications that come in both forms, the "T with a dot" indicates tablet, while "cap" would mean capsule. Very few would write for dosing in teaspoons, etc., although if they did, it would be "tsp.", etc.
