Analyzing Prescription Data and Morphine Milligram Equivalents (MME)

CDC’s Injury Center has compiled a listing of medications by National Drug Code to help with analyzing prescription data at the population level. This data file is intended solely for research, surveillance, and other monitoring purposes. In addition to prescription benzodiazepines, muscle relaxants, stimulants, and sedatives, the file contains opioids with their estimated oral morphine milligram equivalent (MME) conversion factors. The following information is provided for all drugs: product name, generic name, form, Drug Enforcement Administration (DEA) Schedule, strength, and unit of measure. Please see the Documentation within the data files for the MME per day formula.

The files below may be useful for:

  • Research
  • Retrospective drug utilization reviews
  • Surveillance

Note: This file is not intended for clinical decision-making. It is intended only for analytic purposes where prescription data are used to calculate MME to inform understanding of population-level risks associated with opioid prescribing for pain. For clinical guidance on dosage of opioids for treatment of chronic pain, including conversion factors for commonly prescribed opioids, see our provider resources on calculating daily dose for commonly prescribed opioids.
