What are Sig Codes!?

If you’ve ever received a handwritten prescription and aren’t sure what all of the codes and initials mean, you’re not alone! Sig codes are a way for the doctor to communicate to the pharmacy which medication the patient should take, when it should be taken, and how much of it should be taken. Most sig codes are derived from the Latin language which can make them a bit more confusing, so at KLR Pharmacy Technician Training School, we use handy clues to remember some of the trickier ones! It is also important to note that sig codes can be written in capital or lowercase letters; either way they indicate the same meaning. Here is a guide to keep on hand of some of the most frequently used sig codes and their meanings for prescriptions!

Sig code are a more a easy way for doctors and pharmacist to communicate with each other. They are shorter code words that help health care providers communicate faster and discreetly I believe that the most commonly used Sig code would be PO because most medications are taken by mouth. I worked as a Cna/ HHA most of my life, we used a lot of these sig codes for documentation as well.
