As and when needed

Use it when the prescription does not call for any timed dosage.

Hi,

Actually there is a abbreviation for this as and when. I want to use it in prescription. How to write is the question.

-- Nice tab - take as and when required ( abbreviation)

Hi,

AnonymousHow to use abbreviatin - as and when needed in med. prescription?

It is abbreviated as "PRN or prn" or even it can be s.o.s ( si opus sit )

PRN/prn = pro re nata ( Latin ); as needed ( English ).

For example: ibuprofen ( pain killer )

1.ibuprofen *** mg PRN/prn = Take ibuprofen as needed.

2. ibuprofen

Alas, there is no abbreviation for the exact words "as and when needed".

There are, however, the following:

PRN = "As Needed" (from the Latin pro re nata). (also written in lowercase as p.r.n.)¹.

SOS = "If needed" (from the Latin: si opus sit)¹.

Whenever a medication is prescribed as prn...then medication prescription safety praactices also require the following to be written

1 - The indication for taking the drug

2 - The maximum number of doses (frequency) of the drug which can be given in a day

For Example

Tab. Paracetamol 500 mg PRN ( Indicated if temperature is more than 38 'C. Maximum frequncy q4h
