Association of State Opioid Prescription Duration Limits With Changes in Opioid Prescribing for Medicare Beneficiaries

  • Between March 2016 and July 2018, 23 states implemented legislation limiting the duration of initial opioid prescriptions to a maximum of 7 days (17 states limited to 7 days or less, 2 states to 5 days or less, and 4 states to 3 days or less).
  • State laws limiting opioid prescriptions to 7 day or less were associated with a reduction in opioid prescribing by 1.7 days per enrollee.
  • The state legislation on opioid prescribing primarily targets initial opioid prescriptions provided for acute pain, and we observed decreases that were most pronounced among surgeons and dentists.
