Bid[edit | edit source]

Bid is a term used in the medical field to denote a specific frequency of medication administration. It is derived from the Latin phrase "bis in die," which translates to "twice a day." This term is commonly used in prescriptions and medical instructions to indicate that a medication should be taken two times a day, typically at evenly spaced intervals.

Usage in Medical Prescriptions[edit | edit source]

In medical prescriptions, the abbreviation "bid" is used to instruct patients on how often they should take their medication. For example, a prescription might read "Take 1 tablet bid," meaning the patient should take one tablet twice a day. This is an important aspect of medication adherence, as taking medications at the correct times can significantly impact their effectiveness.

Importance of Timing[edit | edit source]

The timing of medication administration is crucial for maintaining the appropriate therapeutic level of the drug in the bloodstream. Medications prescribed as "bid" are often intended to be taken approximately 12 hours apart, such as in the morning and evening. This helps ensure that the drug concentration remains stable, avoiding peaks and troughs that could reduce efficacy or increase the risk of side effects.
