What does the abbreviation "po" mean in medication administration?

The abbreviation "po" stands for "per os," which is a Latin term that translates to "by mouth." This abbreviation is commonly used in medical settings to indicate that a medication should be taken orally. When a medication is administered po, it is meant to be swallowed, allowing it to be absorbed through the digestive system. This method is one of the most common routes for medication administration as it is convenient and generally well-tolerated by patients.

Understanding this abbreviation is crucial for medication aides, as it directly impacts how a patient receives their treatment. It contrasts with other routes of administration, such as intravenous or intramuscular, where medications are delivered directly into the bloodstream or muscle tissue. Recognizing and interpreting these abbreviations correctly ensures safe and effective medication administration in practice.
