The abbreviation 'AU' stands for "both ears." This notation is often used in medication instructions, particularly with ear drops or other otic preparations. The 'A' stands for "auris," which is Latin for "ear," and the 'U,' from the Latin word 'uterque,' means "both." When a medication is prescribed with the abbreviation 'AU,' it clearly indicates that the treatment should be applied to both ears, ensuring that the patient receives consistent care for any condition affecting both sides.

Understanding this terminology is essential for pharmacy technicians, as it helps prevent errors in medication administration and ensures that patients receive the correct dosage for bilateral conditions. The other options involve specific sides or general instructions but do not accurately convey the meaning of treating both ears simultaneously.
