On a script, BD is a common medical abbreviation derived from the Latin phrase Bis in die, which means "twice a day." When you see BD written on a prescription, it indicates that the medication should be taken two times within a 24-hour period.
Understanding BD in Medical Prescriptions
The use of "BD" on a prescription provides clear instructions for the frequency of medication. This ensures that the drug is administered consistently, helping to maintain therapeutic levels in the body and achieve the desired medical effect. For example, a doctor might prescribe a medication "1 tablet BD," meaning one tablet should be taken twice daily, typically once in the morning and once in the evening, spaced roughly 12 hours apart.
