During opioid tapering, converting the current dose to morphine milligram equivalents (MME) serves what purpose?

• A. To standardize the dose across opioids for accurate tapering.
• B. To determine if non-opioid analgesia should be avoided.
• C. To measure liver enzyme activity.
• D. To predict analgesic efficacy of NSAIDs.

Answer: (A)

Converting to morphine milligram equivalents standardizes potency across different opioids so you can accurately gauge total opioid exposure. Since opioids vary in strength, a milligram of one drug isn’t the same as a milligram of another. Using MME gives a single reference point to sum daily doses, which is essential for planning a safe, gradual taper and for staying within exposure guidelines. It also helps when a patient switches opioids, ensuring the total burden is understood.

This isn’t about liver enzymes, NSAID efficacy, or avoiding non-opioid analgesia. It’s about having a consistent, comparable measure of opioid exposure to guide tapering safely.
