Unless directed by an authorized user, a licensee may not use a dosage if the dosage differs from the prescribed dosage by more than what percent?

In medicine, dosage accuracy is crucial and deviations from the prescribed dosage must not exceed a specific percentage, to prevent potential underdose or overdose and ensure patient safety.

Explanation:

In medicine, a licensee must adhere to the prescribed dosage of medication, unless authorized by a user to do otherwise. The prescribed dosage should not be exceeded by more than a specific percentage to ensure patient safety and efficacy of treatment. For example, a deviation of more than 10% from the prescribed volume in a dilution calculation can significantly impact the final concentration, potentially leading to underdose or overdose risks. As illustrated by the drug survey amongst seniors and the discussion on Type I and II errors, proper dosage administration is critical. Medical and pharmaceutical personnel must be precise with dosage calculations as mistakes can have serious consequences.
