The main risk affiliated with methadone is overdose. Overdose is a particular worry inside the First levels of MMT and when methadone is used in combination with other depressant drugs.
Therapy should be continued only if clinically meaningful enhancement in pain/function outweighs risks. Therapy needs to be initiated at the lowest effective dosage applying rapid-launch opioids (in lieu of prolonged-release/long-performing opioids). Possibility connected with use increases with increased opioid dosages. Risks and benefits ought to be re-evaluated when expanding dosage to ≥50 morphine milligram equivalents (MME)/day orally; dosages ≥ninety MME/working day orally really should be avoided Except carefully justified (Dowell [CDC 2016]).
