What does the "po" abbreviation indicate?

The abbreviation "po" stands for "per os," which is a Latin term meaning "by mouth." This indicates that a medication is to be taken orally. When prescriptions or instructions specify "po," it signifies that the medication will enter the system through the digestive tract, allowing for systemic absorption into the bloodstream. This oral route is one of the most common and convenient methods of administering medication.

Other options refer to different methods of administration: "in the eye" pertains to ocular applications, "topical application" refers to medications applied directly to the skin, and "intravenous" involves delivering medication directly into the bloodstream through a vein. Understanding these distinctions helps in interpreting prescription instructions accurately and ensures proper medication administration.
