When administering medication, what does "au" mean?

"Au" stands for "auris utraque," which is a Latin term meaning "both ears." In the context of medication administration, this abbreviation indicates that the medication is to be administered in both ears, which is particularly relevant for ear drops or treatments that are intended to affect both auditory canals. Understanding the use of "au" is vital for pharmacists and pharmacy technicians to ensure accurate dosages and proper application to patients, especially when working with medications that are sensitive to the distinction between ears or eyes. Recognizing this terminology helps prevent medication errors and enhances the quality of patient care.
