On a prescription, "om" is typically an abbreviation for o.m., which stands for the Latin phrase omni mane, meaning "every morning." This abbreviation indicates that a medication should be taken daily upon waking or at the start of the day.
Understanding Prescription Abbreviations
Medical professionals and pharmacists often use abbreviations on prescriptions for brevity and efficiency. These shorthand notations are derived from Latin terms and allow for clear, concise instructions regarding medication dosage, frequency, and administration. While they save space and time, understanding these abbreviations is crucial for patients to take their medications correctly and safely.
Common Prescription Abbreviations
Knowing common abbreviations can help you understand your prescription instructions. Here are some frequently encountered examples:
| Abbreviation | Latin Term | Meaning |
|---|---|---|
| o.m. | omni mane | Every morning |
| o.n. | omni nocte | Every night |
| p.c. | post cibum | After food |
| p.r.n. | pro re nata | When required |
