Which abbreviation indicates that a medication should be taken two times a day?

The abbreviation that indicates a medication should be taken two times a day is B.I.D., which stands for "bis in die" in Latin. This term directly translates to "twice a day." Healthcare professionals frequently use this abbreviation in prescriptions to provide clear guidance on medication dosages and timing, ensuring that patients take their medications in a manner that maximizes their effectiveness and supports adherence to treatment regimens.

In contrast, the other options represent different dosing schedules. Q.D. means "quaque die," which indicates that a medication should be taken once daily. Q.H. stands for "quaque hora," meaning every hour, which signifies a much more frequent administration. T.I.D. translates to "ter in die," indicating that the medication should be taken three times a day. Understanding these abbreviations is essential for accurately interpreting prescriptions and providing proper patient education.
