What does the abbreviation "au" represent?

The abbreviation "au" stands for "both ears." In medical terminology, "au" is derived from the Latin term "auris utraque," which translates to "each ear." This abbreviation is commonly used in prescriptions and medical documentation to indicate that a treatment or medication should be applied or administered to both ears simultaneously.

Understanding the use of "au" can help pharmacy technicians accurately interpret and fill prescriptions that involve ear treatments, ensuring that patients receive the appropriate care for conditions affecting their hearing or ear health. This clarity is crucial for patient safety and effective treatment outcomes.
