What does BID stand for?

• A. Bedtime
• B. Before meals
• C. After meals
• D. Twice daily

Answer: (D)

Dosing abbreviations explain how often to take a medication. BID means twice daily, from the Latin bis in die, so the medicine is taken two times in each 24-hour period—typically about 12 hours apart (for example, morning and evening). This is about frequency, not the relation to meals, which would be represented by other abbreviations like before meals or after meals. Bedtime dosing is a separate instruction related to timing relative to sleep. If a prescription says a dose is BID, take the specified amount twice in a day unless the clinician provides different timing.
