20 Miss. Code R. § 2-III
Long-term opioid use often begins with treatment of acute pain. When opioids are used for acute pain, clinicians should prescribe (a) the lowest effective dose of immediate release opioids (b) in no greater quantity than needed for the expected duration of the pain that is severe enough to require opioids. Three days or less will often be sufficient. More than seven days will rarely be needed.
Opioids are not the preferred treatment for chronic pain. Non-pharmacologic therapy and non-opioid pharmacologic therapy are preferred for chronic pain. Clinicians should consider opioid therapy only if expected benefits for both pain and function are expected to outweigh risks to the patient. If opioids are used, they should be combined with non-pharmacologic therapy and non-opioid pharmacologic therapy, as appropriate.
