What does QID signify in medication dosing?

QID stands for "quater in die," which is a Latin term meaning "four times a day." This notation is commonly used in medical prescriptions to indicate that the patient should take the medication four times within a 24-hour period. Understanding this abbreviation is crucial for accurately administering medications to animals, as it ensures that the dosages are given at the correct intervals for effective treatment.

The other options reflect different dosing regimens: "once a day" refers to a daily administration, "three times a day" is indicated by TID, and "every 4 hours" typically uses the abbreviation Q4H. By knowing the definitions of these terms and their proper usage in veterinary medicine, medication clerks can help ensure that the prescribed treatments are followed accurately.
