What does the abbreviation "bid" signify in medication dosing?

The abbreviation "bid" stands for "bis in die," a Latin term meaning "twice a day." In medication dosing, this indicates that a patient should take the prescribed medication two times throughout the day. This can help maintain a consistent level of medication in the bloodstream, which is often necessary for therapies targeting chronic conditions or pain management. Understanding such abbreviations is crucial for accurately following prescriptions and ensuring proper medication adherence. The other options represent different dosing intervals: “once daily” is typically indicated by "qd," "three times daily" is stated as "tid," and "every day" is more generally expressed with the word "daily." Each of these has specific meanings that differ from "bid."
