Which abbreviation represents "milligram" in medical prescriptions?

The abbreviation that represents "milligram" in medical prescriptions is "mg." This abbreviation is widely recognized and used in clinical practice to indicate a specific measurement of medication. The term milligram refers to one-thousandth of a gram, which is a standard unit of mass in the metric system.

Using "mg" helps healthcare providers to accurately prescribe and administer doses of medication, ensuring that patients receive the correct amount for their treatment. This is crucial in preventing medication errors and ensuring patient safety, as dosages can vary widely depending on the medication and the condition being treated.

The other abbreviations do not represent "milligram." For example, "gm" stands for "gram," which is a larger unit of measurement than a milligram. "sq" or "SQ" refers to subcutaneous, indicating a method of medication administration rather than a dosage measurement. Lastly, "qod" or "QOD" means "every other day," which relates to the frequency of taking medication, not the dosage amount. Understanding these distinctions helps in interpreting prescriptions correctly and safely administering medications.
