What is the meaning of the abbreviation "qd"?

The abbreviation "qd" stands for "quaque die," which is Latin for "once a day" or "every day." This term is commonly used in the medical field to indicate that a medication should be taken daily. Understanding this abbreviation is crucial for pharmacy technicians, as it ensures that medications are dispensed and administered correctly according to the prescribed frequency. The other options represent different dosing schedules that are not associated with "qd," making it important to distinguish between them to avoid potential medication errors.
