QID represents which dosing frequency?

• A. Three Times a Day
• B. Once Daily
• C. Four Times a Day
• D. Twice Daily

Answer: (C)

QID represents four times a day because it comes from the Latin phrase quater in die, meaning dosing four times within a 24-hour period. That makes four dosing events per day the intended frequency. In other common abbreviations, taking a medication twice daily is BID, three times daily is TID, and once daily is QD (or daily). So the reason this is the best answer is that QID is the shorthand used to indicate four separate doses each day, typically spaced to roughly six hours apart unless the prescription provides different timing.
