What is the meaning of the term 'QID' when referenced on a prescription?

The term 'QID' is derived from Latin and stands for "quater in die," which translates to "four times a day." When this abbreviation appears on a prescription, it indicates that the medication should be administered four times within a 24-hour period. This is important for properly managing dosages to ensure the effectiveness of the medication and maintain steady levels in the patient's system.

Other options refer to different frequencies of administration: "once a day," "twice a day," and "three times a day" each have their own abbreviations, such as "QD" for once daily, "BID" for twice daily, and "TID" for three times daily. Knowing these abbreviations is crucial for pharmacy technicians to accurately interpret prescriptions and provide appropriate patient care.
