- How Do You Understand Prescription Writings?
-
-
- ------------------------------------------------------------------------------
-
- QUESTION: It is hard enough to read my doctor's handwriting on the
- prescription blank, but there is no way to understand a line of scribbles at
- the bottom which just looks like a string of letters. I am sure you
- understand this puzzle, and I am hoping you will share their meaning with your
- readers. Perhaps you might even explain why doctors use these symbols instead
- of real words?
-
- ------------------------------------------------------------------------------
-
- ANSWER: The reason for scribbling is not readily explainable, but the letters
- do have meanings and they are most important in your understanding just how
- the medication is to be used. The medication and its form is usually named in
- the upper part of the prescription blank. The bottom line usually starts with
- the letters "SIG", an abbreviation from the Latin "signa" meaning "write".
- Following this are the instructions the physician wishes the pharmacist to
- write on the prescription label. All the rest of the letters which follow the
- SIG are a type of shorthand, that saves a bit of time, but are quite precise
- in their meanings. I can share some of the more commonly used ones with you,
- which may help you decipher your prescription. The better way, of course, is
- to ask questions of both your pharmacist and physician to be sure you
- completely understand the correct use of your medication and why it was
- prescribed.
- The letters "ad lib" mean "take it freely or when needed", while "a.c."
- indicates the medication should be taken "before meals". Conversely "p.c."
- means "after meals". Bedtime medications are indicated with an "h.s.," and
- "ut dict" or "UD" means "as directed. The timing of medications is quite
- important, and there are several notations that deal with this. "q.d." means
- "daily", "b.i.d." means "twice a day", "t.i.d." means "three times a day",
- "q.i.d." denotes 4 times a day. If medication must be taken very regularly,
- the doctor may write "q.4.h." for "every 4 hours" or indicate the exact timing
- between doses by specifying the exact number of hours. There are many others
- but this will give you a working knowledge of the mysteries of prescription
- writing.
