What does the abbreviation "po" stand for in medication administration?

The abbreviation "po" stands for "by mouth," which indicates that a medication is to be taken orally. This route of administration is common for many forms of medicine, including tablets, capsules, and liquids, which are designed to be swallowed and absorbed through the gastrointestinal tract.

Using "by mouth" as a route of administration is significant because it helps healthcare professionals convey clear instructions on how a patient should take their medication, ensuring that the medication is properly administered and absorbed. This method is preferred for many patients due to its convenience and non-invasive nature.

Other routes of administration, such as intravenous, subcutaneous, or rectal, involve different methods of delivering medication that are used in specific clinical situations, but they do not correspond to the abbreviation "po."
