Which acronym is used when administering medication twice a day?

• A. TID
• B. SID
• C. BID
• D. QID

Answer: (C)

Dosing frequency abbreviations tell you how often to give a medication. The one used for twice daily dosing is BID, which comes from the Latin bis in die, meaning twice in a day. This is contrasted with SID for once daily, TID for three times daily, and QID for four times daily. Using BID helps space the dose about 12 hours apart, which helps maintain therapeutic drug levels and steady effect. In practice, this often means dosing in the morning and evening, such as roughly every 12 hours.
