What does the abbreviation 'PO' stand for when referring to medication routes?

The abbreviation 'PO' stands for "per os," which is a Latin term that translates to "by mouth" or "orally." This indicates that a medication should be taken through the mouth and swallowed. It is one of the most common routes for administering medications, as it is often used for pills, capsules, and liquid forms that are ingested.

This method of administration is favored for many medications because it is convenient and generally safe, allowing for self-administration by patients. Understanding common abbreviations like 'PO' is essential for medication technicians to ensure correct administration and communication in a clinical setting.
