Which abbreviation indicates a twice-daily dosing schedule?

• A. qid
• B. bid
• C. tid
• D. qhs

Answer: (B)

Dosing frequency abbreviations tell you how often to take a medication. The one that indicates taking it twice in one day is bid, short for bis in die, meaning two doses per day (usually about every 12 hours). The other common abbreviations here indicate different frequencies: qid means four times daily, tid means three times daily, and qhs means at bedtime. So bid is the correct indicator for twice-daily dosing.
