Analyzing Prescription Data and Morphine Milligram Equivalents

These files below may be useful for:

  • Researchers
  • Pharmacy benefit managers
  • Prescription monitoring programs
  • Others who analyze prescription data for the purpose of preventing prescription drug misuse, abuse, and overdose.

CDC’s Injury Center has compiled a listing of medications at the National Drug Code level to help with analyzing prescription data for the purpose of preventing prescription drug misuse, abuse, and overdose. In addition to prescription benzodiazepines, muscle relaxants, stimulants, and zolpidem, the file contains opioids with their oral morphine milligram equivalent (MME) conversion factors. The following information is provided for all drugs: product name, generic name, master form, DEA Schedule, strength, and unit of measure. Please see the Documentation for the MME per day formula.

Use of this file for clinical decision-making warrants caution. The MME conversion factor is intended only for analytic purposes where prescription data are used to calculate MME to inform analyses of risks associated with opioid prescribing for pain. The conversion factors for drugs prescribed or provided as part of medication-assisted treatment for opioid use disorder should not be used to benchmark against dosage thresholds meant for opioids prescribed for pain. In addition, the conversion factors do not constitute clinical guidance or recommendations. For guidance on dosage of opioids for treatment of chronic pain, including conversion factors for commonly prescribed opioids, please see the CDC Guideline for Prescribing Opioids for Chronic Pain. For guidance regarding converting patients from one form of opioid pain medication to another, or for guidance on dosing of medication-assisted treatments for opioid use disorder, please consult the manufacturers’ full prescribing information.

Data Files

Data files of select controlled substances including opioids with oral morphine milligram equivalent conversion factors, 2016 version.


SAS Merging Program

This SAS program merges a data file containing dispensed controlled drug information (e.g., an outpatient prescription drug file) with CDC's data file of controlled substances with MME conversion factors.
