Which abbreviation represents the left ear in medical prescriptions?

The abbreviation that represents the left ear in medical prescriptions is "AS," which stands for auris sinistra in Latin. This term is commonly used in medical settings to indicate procedures or prescriptions specifically for the left ear.

In the context of otic medications or other treatments related to the ears, using the correct abbreviation helps prevent errors and ensures that patients receive the appropriate care. Knowing this terminology is essential for pharmacists and healthcare providers to communicate effectively about patient care.

Other abbreviations, such as AU, AD, and OS, refer to different anatomical locations. AU signifies both ears (auris uterque), AD indicates the right ear (auris dextra), and OS denotes the left eye (oculus sinister). This distinction is crucial in pharmacology to avoid confusion and maintain accurate patient records.
