opioid painkillers are best reserved for short bursts of acute relief — roughly four weeks or less — and may do more harm than good when prescribed for chronic pain, according to researchers at the University of Alberta. Their review of the available evidence challenges the long-standing practice of keeping patients on these powerful drugs for months or even years, a pattern that has fuelled addiction crises in several countries.
The team found little reliable evidence that prolonged opioid use delivers meaningful, lasting pain relief for chronic conditions, while the risks of dependence, tolerance and overdose climb steadily the longer treatment continues. For acute pain after surgery or injury, by contrast, opioids can still play a legitimate and tightly bounded role. The researchers argue that the findings should push clinicians and patients toward a frank conversation about what these medications can and cannot do, and toward alternative strategies — physical therapy, non-opioid drugs and psychological support — for the millions living with persistent pain.
