Which abbreviation is used for administering medication every 12 hours?

The abbreviation used for administering medication every 12 hours is BID, which stands for "bis in die" in Latin. This term translates to "twice a day," indicating that the medication should be given two times within a 24-hour period, which corresponds to every 12 hours.

This scheduling helps in maintaining a steady level of the medication in the patient’s system, ensuring effective treatment while avoiding fluctuations that could occur with less frequent dosing. The other terms have different meanings; TID stands for "ter in die," meaning three times a day, QID means "quater in die," or four times a day, and Q4hr indicates administration every four hours. Understanding these abbreviations is crucial for proper medication administration in veterinary settings, ensuring patients receive their treatments at the correct intervals.
