What is the term for any dose that is either above or below the correct dosage?

The term "wrong dosage" specifically refers to any dose that deviates from the correct dosage, whether it is higher or lower than what is prescribed or necessary for the patient. This term succinctly captures the essence of dosage errors and is commonly understood in the context of medication administration. It reflects an understanding that both overdose and underdose can significantly impact patient safety and the effectiveness of treatment.

The other options, while they may seem relevant, are not as widely used or may lack the specificity preferred in clinical discussions. "Incorrect dose" could be seen as a synonym but is less precise and less commonly used in clinical practice. "Inappropriate dosage" might imply a broader context of therapeutic appropriateness rather than strictly dosage errors. "Misadministration" suggests errors in the process of giving the medication rather than focusing on the specific dosages themselves. Hence, "wrong dosage" is the most accurate term for the scenario described.
