The abbreviation ‘au’ in medical terminology stands for ‘auris utraque’, which is Latin for ‘both ears’. This term is often used in prescriptions and medical documentation to indicate that a treatment or examination applies to both ears.
For example, if a doctor prescribes ear drops and writes ‘au’, it means the drops should be administered in both the left and right ears. Understanding this abbreviation is important for ensuring that patients receive the correct treatments in the appropriate locations.
