What does AS indicate in a prescription for ear medication?

In veterinary prescriptions, the abbreviation "AS" stands for "auris sinistra," which is Latin for "left ear." This notation is used to specify that the medication should be administered to the left ear of the animal. Understanding these abbreviations is crucial for ensuring the correct administration of medications and avoiding potential errors that could result from confusion between left and right ears.

In veterinary practice, clarity in prescription writing is essential, and using these standardized abbreviations helps both the prescribing veterinarian and the pharmacy staff communicate effectively about the treatment plan. Knowing that "AS" indicates the left ear can help prevent any mix-ups during medication administration.
