There is much debate about both the usefulness and safety of opioids as a medication for FM sufferers. Many health care professionals and researchers feel that there is little evidence that opioids actually provide significant pain relief for those suffering with FM. Others are concerned about the potential for tolerance and addiction associated with long-term opioid use. Yet, many of us find that opioids are highly effective pain relievers, and work to relieve persistent symptoms of widespread pain and muscle stiffness.
What are Opioids?
Opioids are a class of drug used to relieve symptoms of severe pain. More commonly known as narcotics, opioids are named after opium, a product found inside of the opium poppy plant. Natural opium has been used for hundreds of years to treat symptoms of severe pain and illness. Some opioids are made from this natural opium, while others are made synthetically from different chemicals.
Most of us associate opioids with the treatment of acute pain, like when you get your wisdom teeth pulled at your dentist’s office. However, opioids can also be used on a regular basis to treat chronic pain. Some types of opioids used to treat FM include:
Do Opioids Help to Relieve Fibromyalgia Pain?
The efficacy of opioids in FM pain relief is one of the key components to the controversy surrounding opioid use. Though patients claim that opioids provide them with significant symptom relief, some health care providers disagree. There is some research that shows that opioids are indeed helpful for relieving FM pain. A recent study performed on long-acting opioids, including oxycodone, showed that FM sufferers gained great relief from long-term use of opioids. Users reported a 38% average reduction in pain symptoms and also experienced:
- fewer sleep disturbances
- less anxiety and depression
- increased mobility and enjoyment of life
However, another study published discourages long-term use of opioids for treating FM pain. In a review of charts at a multidisciplinary FM clinic, researchers found that 32% of patients were taking opioids (i.e., Vicodin, Percocet, OxyContin,) with more than 2/3 of them on strong ones.
Researchers identified several characteristics that made people more likely to be on long-term opioids: lower education, unemployment, being on disability, current unstable psychiatric disorder, history of substance abuse and prior suicide attempts. They also say they “observed negative health and psychosocial status in patients using opioids.”
The paper supports the current medical opinion discouraging opioid use in fibromyalgia and concludes that prolonged use requires evaluation.
It is very common to hear doctors say that these drugs are ineffective in FM, but so far there is very little (and differing) research to go on. The patient community is divided, with some saying they don’t work and others saying they’re the only drugs that do anything. Response to opioids is variable.
Then the issues of abuse and addiction further complicate the matter, especially with doctors afraid of serious legal consequences for what may be considered improper prescribing.
Do Opioids Cause Addiction?
Despite their effectiveness, many patients and health care providers are concerned about the possibilities that opioids may cause tolerance, addiction and physical dependence in patients. Three major medical societies, the American Academy of Pain Medicine (AAPM), the American Pain Society (APS), and the American Society of Addiction Medicine (ASAM) have issued a joint consensus paper which clearly defines the frequently misunderstood terms addiction, tolerance,and physical dependence, and discusses their definitions in the context of opioid use in the treatment of pain.
“The addiction community was concerned because of inaccurate diagnosis. The pain community was concerned about over-diagnosis of addiction when it didn’t exist, and how this misdiagnosis interfered with treatment with opioids,” said Edward Covington, MD, Director of the Chronic Pain Rehabilitation Program at the Cleveland Clinic and past president of AAPM, who was one of the paper’s authors. “Also we needed agreement about what is and what is not an addictive disorder.”
Tolerance: Tolerance is actually a typical response to any type of medical intervention. After about two weeks on a medication your body becomes “used to it,” and side effects caused by the medication begin to disappear. Opioid tolerance typically manifests as the disappearance of nausea and other side effects. However, some patients do notice that they begin to develop a tolerance to the pain relief provided by opioids. This does not always indicate that your body is becoming addicted to the medication. Other factors, such as muscle injury and central nervous system activity must also be taken into consideration. Also, tolerance is not the same thing as addiction – it simply means that you may require a slight increase in the dosage of the opioid you are taking in order to gain the maximum benefits.
Physical dependence and tolerance are often confused with addiction.
Addiction: Addiction is a more worrying side effect of opioid usage. Dr. Covington noted that addiction is a primary, chronic, neurobiological disease that can be identified by the three “Cs” Craving or Compulsive use, loss of Control, and use despite adverse Consequences. Other behaviors that signal addiction include “drug seeking” behavior, taking multiple doses of medications, and an inability to take them on schedule, “doctor shopping,” frequent reports of lost or stolen prescriptions, isolation from friends and family members, and taking pain medications for sedation, increased energy, or to get “high.” This can result in a multitude of side effects, both physical and psychological.
However, less than 0.5% of chronic pain patients develop a real opioid addiction. In an evidence-based review for Pain Treatment Topics, editor Stewart B. Leavitt, MA, PhD, summarised the findings of major research investigations of 24 clinical studies: the overall rate of prescribed opioid analgesic abuse or addiction in patients with pain was about 3.3%. However, fewer than 2 out of 1,000 (0.19%) patients without a current or past substance-use disorder experienced problems with opioids prescribed for pain.
According to the consensus paper definitions, physical dependence and tolerance are both normal responses to regular use of some prescribed medications, including opioids, and are not in themselves evidence of an addictive disorder.
“Unlike tolerance and physical dependence, addiction is not a predictable effect of [taking] a drug but an adverse reaction in biologically and psycho-socially vulnerable individuals.
“It is also important for healthcare professionals to recognise the difference between true addiction and “pseudo-addiction,” notes Albert Ray, MD, President of AAPM.
With pseudo-addiction, patients whose pain is under-treated appear to behave “like addicts” to get the pain relief they need. They may focus on getting more medication, for example, and appear to be engaging in drug-seeking behavior. But unlike a person with a true addictive disorder, however, once their pain is properly managed, these behaviors stop immediately.”
Withdrawal: Opioid use has also been debated because of the withdrawal symptoms that they often cause. Even patients that are not addicted to an opioid will likely experience disturbing withdrawal symptoms when they stop taking the drug. To avoid serious withdrawal symptoms, opioid use should always be tapered off gradually. Symptoms of opioid withdrawal include:
- runny nose
- drug cravings
Most withdrawal symptoms should disappear within a week. However, symptoms of anxiety, insomnia, and craving may persist for a longer period of time.
This topic is worthy of further investigation and debate; however, the preponderance of available evidence suggests that establishing
medical policies or practices in pain management on a presumption of high rates of prescribed opioid-analgesic abuse or addiction could be misguided, resulting in added costs for healthcare delivery and the under-treatment of pain.
Healthcare providers should be reasonably assured that only a very small percentage of their patients with chronic pain, if any, will exhibit abuse/addiction when receiving long-term opioid analgesics. And, this would be especially so in those patients who have not experienced substance-misuse problems in the past.
Talking with Your Doctor
Talking with your doctor about an opioid prescription can be a nerve-wracking experience. This is because, in the past, health care providers were strongly advised to avoid prescribing opioids at all costs.
It is important to provide your doctor with as much information as possible about your symptoms and their severity. Health care providers are not always aware of how much pain their patients really feel and are thus reluctant to prescribe narcotics.
If you are in a lot of pain, record your symptoms and rank their severity on a scale of one to ten. This will help your doctor to understand how much pain you are actually experiencing. Also, explain to your health care provider how your symptoms are affecting your daily life. If your doctor can see how your symptoms are impacting upon your daily routine, she may be better able to provide you with the right type of prescription for your symptoms.
