B.i.d.

B.i.d. is an abbreviation for the Latin phrase "bis in die," which translates to "twice a day." It is commonly used in medical prescriptions to indicate that a medication should be taken two times a day. This term is part of the medical abbreviations that are frequently used by healthcare professionals to provide clear and concise instructions for medication administration.

Usage in Medical Prescriptions

In the context of medical prescriptions, "b.i.d." is used to specify the frequency of medication intake. For example, if a doctor prescribes a medication with the instruction "Take 1 tablet b.i.d.," it means the patient should take one tablet twice a day. This helps ensure that the medication is administered at appropriate intervals to maintain its effectiveness.

Importance of Adherence

Adherence to the prescribed frequency, such as b.i.d., is crucial for the effectiveness of the treatment. Non-adherence can lead to suboptimal therapeutic outcomes, potential side effects, or the development of antibiotic resistance in the case of antibiotic treatments.
