Therapy must be ongoing provided that clinically meaningful advancement in pain/function outweighs risks. Therapy really should be initiated at the lowest effective dosage using fast-release opioids (in place of extended-release/long-acting opioids). Danger connected with use raises with bigger opioid dosages. Risks and Gains really should be re-evaluated when raising dosage to ≥fifty morphine milligram equivalents (MME)/working day orally; dosages ≥90 MME/working day orally really should be avoided Except carefully justified (Dowell [CDC 2016]). Ought to only be prescribed by health care professionals who are knowledgeable in using strong opioids for chronic pain management.
