What does "Q2H" stand for in medical prescriptions?

"Q2H" is a medical abbreviation that stands for "every 2 hours." This notation is commonly used in prescriptions and medical orders to indicate the frequency with which a medication should be administered.

In this context, "Q" derives from the Latin word "quaque," meaning "every," and the "2H" specifies the interval of two hours. Therefore, when a physician writes "Q2H," it clearly communicates to the healthcare team that the medication is to be given at two-hour intervals throughout the day.

Understanding such abbreviations is crucial for medical scribes as they help ensure accurate documentation and adherence to medication schedules, which are vital for patient safety and treatment efficacy.
