What is the abbreviation for antibiotics?

The abbreviation for antibiotics is commonly understood to be "ABX." This is a widely accepted shorthand used in medical documentation and prescriptions, making it easier for healthcare professionals to communicate effectively regarding the use of antibiotics in patient care. This abbreviation helps to streamline conversations and documentation, especially in environments where quick references to medications are necessary.

The other abbreviations listed do not reflect the standard terminology used in medical settings for antibiotics. "ATB" is occasionally used in certain contexts but is not as universally recognized as "ABX." "ANT" and "AXB" are not standard abbreviations and may not be understood by healthcare professionals, which could lead to confusion in clinical communication. Therefore, "ABX" stands out as the correct choice for denoting antibiotics.
