What does t.i.d. stand for?

Three times a day Twice daily Four times a day Once daily

Correct Answer:

Three times a day

Explanation:

Dosing schedules use shorthand from Latin to indicate how often a medication should be taken. tid stands for ter in die, meaning three times a day. This usually means doses spaced about every eight hours within a 24-hour period, often morning, afternoon, and evening, unless the prescriber specifies different times. Other frequencies use different abbreviations: twice daily is commonly bid, four times daily is qid, and once daily is qd. So three times daily is the correct interpretation for tid.
