What does the abbreviation qid signify in medication administration?

The abbreviation "qid" stands for "quater in die," which is Latin for "four times a day." This term indicates the frequency with which a medication should be administered. When a healthcare provider orders a medication to be given qid, it means that the patient should receive the medication four separate times throughout a 24-hour period. This schedule is often used for medications that require consistent levels in the bloodstream to be effective or to manage certain medical conditions. Understanding these abbreviations is crucial for ensuring correct dosing and timing of medications for patient safety and effective treatment.
