Rethinking opioid use


Pain, unfortunately, is all too common. We have a natural aversion to it, and many patients have the expectation that it should be treated with medication. This is understandable.

But when it comes to treating pain with medication, we have a problem: our options are limited, and the drugs we have often don’t work very well. We typically start with painkillers such acetaminophen or anti-inflammatory drugs (ASA, ibuprofen, naproxen and a dozen others). But for some people they aren’t safe or they just don’t work. Increasingly, the next step is a trial of – drugs like codeine, morphine, oxycodone, hydromorphone and others. These drugs are derived, directly or indirectly, from the opium poppy, and they are now taken by millions of North Americans daily. It is difficult to argue that this is a good thing.

In the past, painkillers were reserved for severe pain (for example, pain resulting from a fracture), cancer pain, or pain at the end-of-life. Opioids were rarely prescribed for chronic pain because doctors were fearful of the risks, including the development of addiction. In the mid-1990s, the landscape began to change, and opioids were prescribed with increasing frequency to millions with chronic pain. This change reflected a “new approach” (as it was cast at the time) of thinking about chronic pain. Eager to make their patients feel better, physicians accepted this new approach uncritically, oblivious to the paucity of evidence supporting the practice. In fact even 20 years later, no studies have shown opioid therapy to be a safe and effective long-term treatment for pain. Nevertheless, countless patients receive prescription opioids, often at inordinately high dosages. Many of them are being actively harmed by treatment, and it is estimated that between 10,000 to 20,000 Canadians have died from opioids since 1995.


Patients who take opioids rapidly develop tolerance to the drugs. In other words, pain relief lessens over time, often leading patient or prescriber to increase the dose. Even regular users who follow their doctor’s advice to the letter develop physical dependence, which can make it difficult to lower the dose or stop therapy without developing unpleasant side effects. Many patients come to believe they need opioids to function normally, when in fact the drugs are needed to avoid experiencing opioid withdrawal. To make matters worse, as doses escalate, opioids can actually make pain worse. Few physicians and even fewer patients appreciate that opioid-induced hyperalgesia can actively undermine efforts to relieve pain, and increase the dose further in a desperate but futile search for relief.

Even leading pain experts who once espoused the use of opioids for chronic pain now acknowledge that the role of these drugs needs to change. At the core of the discussion is a simple, unarguable principle of medical care: the benefits of a therapy should exceed its risks, ideally by a large margin. With opioids, this is clearly not happening.

What changes should occur? An important first step is for doctors, pharmacists and nurses to help manage expectations about what pain medicines can and cannot do. Physicians and patients alike need better education about the many risks of long term opioid use. There should be a frank discussion between physicians and patients at the outset of therapy regarding the goals of treatment, with a clear “exit strategy” if those objectives are not met.


Prescribers must resist the urge to increase the dose of opioids in response to ongoing pain. Continued pain is expected, in part because opioids aren’t as good at treating chronic pain as we’ve been led to believe, and in part because of the development of tolerance as noted above. In early 2016, it is anticipated that the United States Centres for Disease Control and Prevention will publish new guidelines for the use of opioids in chronic pain, recommending a threshold dose of 90 milligrams of morphine (or equivalent) per day. If heeded, this recommendation alone could save hundreds or perhaps thousands of lives every year.

We also need to emphasize the importance of non-drug therapies in certain pain states. For example, exercise can significantly benefit patients with fibromyalgia, while weight loss can lessen pain from osteoarthritis. While these interventions are more difficult than simply taking a pill, non-drug interventions can sometimes go a long way toward helping patients improve quality of life while limiting the use of opioids.

We practice in a culture that expects (and to a certain extent facilitates) the prescribing of medication for many of life’s challenges, including pain. Sometimes opioids are needed, but for many patients with chronic pain they afford more harm than their benefits justify. We have to rethink how we treat pain. Until we have better drug therapies, we must respect a fundamental tenet of medical practice: never make the treatment worse than the disease.


  1. I have been a chronic pain sufferer for more than 20 years due to a high speed head on collision with a drunk driver. I had several injuries including many broken bones. I followed my doctors recommendations carefully that included exercise, proper diet and non-opiate pain medication. As the years have gone by, I have gotten older and the pain has gotten worse. Typical over the counter pain meds did not give any relief after several years, my doctor at the time did not believe opiate pain medication was suitable for chronic pain. I continued to suffer and withdrew from day to day activities like daily walks, grass cutting etc. I gained weight due to the lack of activity I once enjoyed and of course the pain got worse. My doctor retired and after a few years I found a new family doctor. My new doctor put me on a anti-inflammatory medication and a med for seizures that was supposed to have pain relief properties. The side effects of these meds were terrible and after a year on them without much success I got a bleeding stomach ulcer among other problems, I had to discontinue this treatment. I was then asked to try a long acting opiate pain medicine with a short acting one for break through pain. This was 9 years ago, since starting on these opiate pain meds I have not increased my dosage and have not seen the need to do so. They work great at 12mg twice daily and a few 4mg short acting for break through, since I have been on opiate pain medication treatment my quality of life has increased back to 100%. I lost weight and resumed daily activities and feel like I am once again contributing to my family. I understand that opiate type meds are not for everyone and should not be the first line of treatment, but they are an effective means for treating chronic pain. Patients must be made to understand that more is not always better and that some pain is normal to help remind one self not to overdue it. Over this past 9 years I have felt at times my meds were not working as they once did, so I came up with a simple solution for myself…..every 4 months or so I would reduce the amount of medication for 10 to 14 days to 50%. When I resumed the opiate medication back to the normal dose I was taking, it worked again just fine for another 4+months. These occasional medication dosage reductions seem to reset my brains ability to work with my original dosage and prevent the need for higher dosages or quantities. The 10 to 14 days I’m doing this is slightly uncomfortable but is worth while to help prevent tolerance. The opiate medication alone is not enough, regular activity and a good diet are also necessary. Combination treatment of physical activity, healthy eating habits + opiate pain meds have given me back control of my pain and most importantly my life! I realize there has been many examples of misuse of opiate pain meds, but with a responsible doctor as I have that monitors my use and tests me occasionally it is a useful treatment method for chronic pain. Not once in the 9 years of opiate treatment have I gone to my doctor with excuses of I lost my meds or some such story, in fact I agreed that this would never happen. I agreed that if I misuse my medication treatment he would have me leave his practice. This type of treatment has to be responsibly monitored by the treating physician and responsibly used by the patient.
