In medical shorthand, what does "PO" specifically refer to in a prescription?

In medical shorthand, "PO" stands for "per os," which is Latin for "by mouth." This term specifically indicates that a medication is to be taken orally, allowing the drug to be absorbed through the gastrointestinal tract. It distinguishes the oral route of administration from other methods such as intravenous or intramuscular routes.

Understanding this terminology is crucial for medical scribes and healthcare providers, as it guides them in documenting and communicating medication administration instructions clearly and accurately. It is essential to correctly interpret these abbreviations to ensure patient safety and effective treatment plans.
