What is the administration route indicated by the abbreviation "bid"?

The abbreviation "bid" stands for "bis in die," which is Latin for "twice a day." This administration route indicates that a medication should be taken two times each day, usually at evenly spaced intervals to maintain effective drug levels in the body. Understanding this abbreviation is essential for accurate medication dispensing and ensuring patient adherence to their medication regimen, as it clarifies the frequency with which a patient should take their medication.

In contrast, the other choices represent different instructions for medication administration. "Before meals" would indicate a timing related to food intake, while "at bedtime" specifies a particular time of day for administration. "As directed" suggests that the patient should follow specific instructions provided by their healthcare provider without any fixed schedule implied. Recognizing the meaning of "bid" is crucial for pharmacy technicians to ensure correct interpretation and communication regarding medication orders.
