What does 'QID' stand for?

'QID' stands for "quater in die," which is a Latin phrase meaning "four times a day." In medical terminology, abbreviations like 'QID' are commonly used to indicate the frequency of medication administration. Understanding these abbreviations is essential for ensuring proper medication dosing and scheduling, which is a critical aspect of patient care.

The other options represent different frequencies of drug administration: "once daily" means the medication is taken once a day, "twice a day" refers to taking it two times a day, and "as needed" indicates that the medication should be taken only when necessary, rather than on a fixed schedule. Knowing these distinctions will help in accurately interpreting medication instructions and ensuring adherence to a prescribed treatment plan.
