When administering medication, what does 'AU' refer to?

The abbreviation 'AU' stands for "auris utra," which is derived from Latin and means "both ears." In medication administration, it is crucial to understand these abbreviations to ensure accurate dosing and application of medications, especially in the context of ear drops or other otic medications.

When a medication order specifies 'AU,' it indicates that the treatment should be administered to both the left and right ears simultaneously. This avoids any confusion regarding whether the medication should be applied to one or both ears, thereby promoting effective and safe treatment. Understanding this terminology is essential for healthcare providers to prevent errors and ensure the best possible care for patients.
