What does the abbreviation BID mean in a medication schedule?

The abbreviation BID in a medication schedule stands for "bis in die," which is Latin for "twice a day." This term indicates that a medication should be administered two times within a 24-hour period, typically spaced evenly throughout the day to maintain consistent therapeutic levels in the bloodstream. This standard scheduling helps ensure optimal effectiveness of the medication and minimizes the risk of missing doses. Understanding these abbreviations is crucial for proper medication administration, as it ensures that patients receive their medications at the right times and in the correct dosages, contributing to the overall effectiveness of their treatment plan.
