What does the abbreviation "q.d." mean in prescription writing?

The abbreviation "q.d." stands for "quaque die," which is a Latin term that translates to "once daily." This term is commonly used in prescriptions to indicate that a medication should be taken one time each day. This is significant in helping ensure patient compliance and understanding of their medication regimen, as it establishes a clear dosing frequency.

In contrast to this, other abbreviations have specific meanings that differ from once daily. For example, "q.h." would refer to "every hour," which indicates a much more frequent dosing schedule that is not applicable in this case. "q.o.d." means "every other day," indicating a dosing frequency that is less frequent than daily. Lastly, "b.i.d." stands for "twice a day," which specifies a dosing schedule that occurs twice within a 24-hour period. Understanding these abbreviations is crucial for accurate medication administration and patient care in pharmacy practice.
