Which abbreviation is used for both ears in medication administration?

The abbreviation used for both ears in medication administration is "AU." This term comes from the Latin "auris unitas," which translates to "both ears." In clinical practice, "AU" indicates that a medication or treatment is to be applied or administered in both ears, ensuring that healthcare providers are clear on the intended administration method.

Understanding abbreviations is crucial in medical settings to prevent medication errors and ensure proper dosage and application. The other abbreviations serve different purposes: "AD" refers to the right ear, "AS" refers to the left ear, and "OD" typically denotes the right eye in ocular medication contexts. Thus, using "AU" is essential for clear communication regarding treatments for both ears.
