In prescription abbreviation, "bid" indicates how often a medication should be taken?

  1. Once a day

  2. Every other day

  3. Twice a day

  4. Three times a day

The correct answer is: Twice a day

The abbreviation "bid" is derived from the Latin phrase "bis in die," which translates to "twice a day." Therefore, when this abbreviation is used in a prescription, it instructs the patient to take the medication two times throughout the day. This aligns with the common usage in medical prescriptions to ensure that medications with specific dosing requirements are administered at regular intervals for optimal effectiveness. The other options refer to different dosing regimens, but "bid" specifically denotes taking a medication twice daily.
