What does the abbreviation 'OU' signify in a veterinary prescription?

The abbreviation 'OU' in a veterinary prescription specifically stands for "both eyes." This term is derived from the Latin "oculus uterque," meaning both eyes. It is commonly used when a medication or treatment needs to be applied to both eyes of an animal, and it helps to avoid any potential ambiguity in the prescription. By indicating 'OU,' veterinarians communicate clearly that the treatment is necessary for both ocular regions, which is particularly important in cases of conditions that affect vision or eye health.

Understanding this abbreviation is crucial for veterinary assistants, as accurate administration of medications is key to effective patient care. It helps ensure that the assistant administers treatments correctly as prescribed, contributing to the overall health and recovery of the animal.
