What does BID stand for in medical prescriptions?

BID stands for "bis in die," which is a Latin term meaning "twice a day." This notation is commonly used in medical prescriptions to indicate that a medication should be taken two times throughout the day, typically spaced evenly apart to maintain therapeutic levels in the body. Understanding this abbreviation is essential for both healthcare professionals and patients to ensure the correct dosing schedule is followed, which can play a critical role in the effectiveness of the treatment and the management of health conditions.

The other options refer to different dosing schedules that are conveyed through other specific terms, such as QD for once a day or TID for three times a day, further emphasizing the importance of recognizing and understanding medical abbreviations in patient care.
