What does the abbreviation "BID" signify in a medical context?

The abbreviation "BID" in a medical context stands for "bis in die," which is Latin for "twice a day." This indicates that a medication should be administered two times within a 24-hour period, typically with doses evenly spaced out to maintain effective drug levels in the body. This dosing schedule is common for medications that require consistent therapeutic levels for optimal efficacy while minimizing side effects. Understanding such abbreviations is crucial for proper medication management and ensuring patient adherence to prescribed regimens.
