What does the abbreviation 'AU' stand for in pharmacy terminology?

In pharmacy terminology, the abbreviation 'AU' stands for "both ears." This is derived from the Latin phrase "auris utraque," meaning both ears. It is commonly used in prescriptions and medical documentation to indicate that a treatment, such as ear drops or medication, should be applied to both ears of the patient. Understanding this abbreviation is crucial for pharmacy technicians, as accurate dosage instructions directly affect patient care and the effectiveness of the treatment.

The other abbreviations have distinct meanings: "Right ear" is indicated by a different abbreviation, while "Left ear" has its own specific term. "Every day" is represented by a separate abbreviation commonly used in prescriptions. Recognizing these differences allows pharmacy technicians to provide precise and safe medication instructions.
