What does bid stand for in medication frequency?

• A. Twice a day
• B. Four times a day
• C. Once daily
• D. Three times a day

Answer: (A)

Bid stands for bis in die, meaning twice in a day. It tells you to take the medication two times within a 24-hour period, typically about 12 hours apart to maintain even drug levels. It doesn’t specify exact clock times, just the frequency. For comparison, once daily means take it once per day, three times daily means three doses in one day, and four times daily means four doses in one day.
