What is the meaning of the abbreviation "PO" in medical terms?

The abbreviation "PO" in medical terminology stands for "Per Os," which is a Latin phrase meaning "by mouth." This term is commonly used in prescribing medication or indicating how a treatment should be administered. When a healthcare provider specifies that a medication should be taken PO, they are instructing the patient to take it orally, which is the most common route of medication administration. This is important in the context of patient care as it affects how the medication is absorbed and utilized by the body.

Understanding this terminology is crucial for effective communication within healthcare settings, as it helps ensure that patients receive their medications in the manner intended by their healthcare providers. Recognizing "PO" can aid healthcare providers in conveying clear instructions regarding medication use, thus improving patient safety and treatment outcomes.
