What does the abbreviation 'po' signify in medication administration?

The abbreviation 'po' stands for "per os," which is a Latin term meaning "by mouth." This indicates that a medication is to be administered orally, which is a common route for various medications due to the convenience and effectiveness of this method. When a physician prescribes medication with the instruction 'po', it signals that the patient should take the medication orally, allowing it to be absorbed through the digestive tract.

Understanding this term is crucial for medication technicians, as it directly relates to how they will administer medications to patients. Recognizing that 'po' signifies the oral route helps ensure that medications are given in the correct manner, safeguarding against potential administration errors. It also highlights the importance of following specific instructions about how medications are taken, as some may require food or specific timing relative to meals for optimal effectiveness.
