In medical prescriptions, "OD," "BD," "BDPC," and "BDAC" are abbreviations used to specify the frequency and timing of medication dosages. These abbreviations are commonly used in healthcare settings, particularly in countries where the British or Latin prescription systems are followed. Here's what each of these abbreviations means:
OD: Once a day
- "OD" stands for "omni die," which is Latin for "once a day." It indicates that the medication should be taken once daily, typically at the same time each day.
BD: Twice a day
- "BD" stands for "bis die," which is Latin for "twice a day." It indicates that the medication should be taken two times daily, with approximately equal spacing between doses.
BDPC: Twice a day after meals
- "BDPC" is an abbreviation that combines "BD" (twice a day) with "PC" (post cibum), which means "after meals." It indicates that the medication should be taken twice daily, specifically after meals.
BDAC: Twice a day before meals
- "BDAC" is an abbreviation that combines "BD" (twice a day) with "AC" (ante cibum), which means "before meals." It indicates that the medication should be taken twice daily, specifically before meals.
These abbreviations help healthcare professionals provide clear instructions to patients about when and how often to take their prescribed medications. It is important to follow these instructions carefully to ensure the medication's effectiveness and minimize the risk of adverse effects. However, it's always a good idea to confirm the dosing instructions with the prescribing healthcare provider or pharmacist to avoid any misunderstandings. Additionally, if you are unsure about any part of your prescription, don't hesitate to ask your healthcare provider for clarification.
