Which term indicates that a patient should take a medication twice a day?

BID is the abbreviation derived from the Latin phrase "bis in die," which translates to "twice a day." In medical prescriptions, this term is commonly used to instruct patients on how often to take their medication. Using BID ensures clarity in communication between healthcare providers and patients regarding dosing schedules, which is crucial for effective treatment adherence.

In contrast, the other options represent different dosing frequencies. QOD stands for "every other day," which indicates the medication is to be taken every second day. QID means "four times a day," signaling that the patient should take their medication four times within a 24-hour period. TID signifies "three times a day," which directs the patient to administer the medication three times daily. Understanding these abbreviations helps healthcare professionals and patients maintain accurate medication regimens.
