6 Letters You Should Know if You Have Fibromyalgia: Part 1

Fibromyalgia pain and fatigue are very difficult and disabling symptoms.  Many people are told by their doctors that the only option for pain reduction is medications like Lyrica, Cymbalta, and others, or psychotherapy and exercise. My experience, and the science of fibromyalgia, say differently. Fibromyalgia isn’t hopeless.  But for most people, there is no miracle cure. On the other hand, if you are open-minded and willing to try some rational things, you can likely address the biological imbalances that underlie the pain, fatigue and other symptoms of fibromyalgia. Then you’re on the road to feeling better.

Two Molecules You Should Know

This post talks about two different molecules that help many people with fibromyalgia and other kinds of chronic pain. The six letters you should know are: LDN and PEA These two will be discussed in two different posts, so you can focus on one at a time. As a medical doctor who has treated thousands of people with fibromyalgia and chronic pain, I find LDN and PEA very interesting. The first reason is that there are some research studies showing plausible mechanisms and also clinical effects on pain and other symptoms. The second reason is that they both go “upstream” from the pain symptom and get closer to the root cause of your pain, compared to pain medications.

Getting Closer to the Source of Pain

When speaking about “upstream” we mean that they work on one or more of the mechanisms of what causes the pain, rather than just blocking the pain. Let’s try to understand that. The conventional view of fibromyalgia is that the pain processing system is sensitized. This means that things which wouldn’t normally hurt a healthy person, can result in pain in someone with fibromyalgia. But conventional medicine is unable to say why it is sensitized. Despite that, we do have growing research looking at a number of pathways by which the pain processing amplifiers in the brain and spinal cord can be “turned up”. There are potential roles for stress hormones, sleep disturbance, and perhaps most importantly, inflammation. The last twenty or so years have shown an explosion of research showing that “sterile inflammation” or immune imbalance are drivers of most chronic illness. Fibromyalgia included. In the case of fibromyalgia, we know that there are changes in immune chemicals called cytokines.  These cytokines are present not only in the peripheral blood but also in the brain and spinal cord. We also have evidence that there is an activation of brain-based immune cells called microglia. Microglial activation causes an increase in a brain-stimulating chemical called glutamate. Too much glutamate creates “excitability” of the brain, and that can explain increased pain, mood changes, and even psychiatric illness, sleep disturbance, irritable bowel syndrome, hormonal abnormalities, and small fiber neuropathy. LDN and PEA both seem to reduce microglial activation and inflammatory cytokines. Both have been shown to reduce pain and help with other symptoms like irritable bowel, mood disturbances, and so on.

The First Three Letters You Need to Know: LDN

LDN is “Low Dose Naltrexone.” LDN stimulates your body to produce more of its own natural pain-blocking chemicals called endorphins or enkephalins. These are compounds that are present in your body already. Every organ in your body has receptors for these compounds. There is evidence that many people with fibromyalgia have reduced the activity of endorphins and enkephalins. Besides blocking pain, enkephalins reduce the activity of immune cells that produce inflammatory chemicals. These inflammatory chemicals, called cytokines, have been implicated in many symptoms that are experienced by people with fibromyalgia, including increased pain sensitivity, brain fog, and fatigue. LDN is a totally different thing than the usual use of Naltrexone. In higher doses, naltrexone blocks the body’s opioid system. This is why it is often prescribed by people with substance abuse to help them avoid using alcohol or narcotic drugs. A few decades ago, it was discovered that the same medication could have a profound effect on chronic pain and inflammation when used a much lower dose. That’s how LDN came into use for pain and inflammation.

The Non-Drug, Drug

LDN works in a way that is quite unusual for medications. Most medications have some kind of direct action on the body, and this creates their therapeutic effect. For instance, opioid medicines like Tramadol or Oxycodone directly bind opioid receptors, and that leads to blocking pain signals. Or if you take thyroid replacement, it is processed by your body, and then it binds to thyroid hormone receptors and stimulates cellular activity. In contrast, LDN itself doesn’t block pain or inflammation. It temporarily blocks your opioid receptors for several hours. This triggers your body to produce more of its own naturally occurring opioids. So your body’s own natural opioids block pain and exert the immune-modulating effects of LDN.

Does LDN Really Work?

While there is nothing that is 100% effective, LDN works in many cases. The existing clinical trials have shown promising results. LDN appears to reduce pain in people with fibromyalgia, and also reduce inflammatory cytokines in the body. It appears to reduce the activation of glial cells. These are the brain cells that are often overactive in fibromyalgia, and they can contribute to a variety of symptoms, including increased pain and brain fog. Because of its subtle anti-inflammatory effects, LDN is used in a variety of pain and inflammatory syndromes. Small studies have shown benefit in fibromyalgia, chronic fatigue syndrome, depression, chronic regional pain syndrome (CRPS), Crohn’s disease, ulcerative colitis, irritable bowel syndrome, Multiple Sclerosis (improved symptoms), and some skin conditions. In my clinical experience, LDN works very well for many people. In some cases,  there are people for whom it has literally made their fibromyalgia “go away”. More commonly, it results in a significant improvement in pain, energy, and often mood. Other diagnoses in which I’ve seen notable improvement include Hashimotos thyroid disease, ulcerative colitis, Crohn’s disease, psoriatic arthritis, osteoarthritis. For people who are interested in a pharmacologic treatment for fibromyalgia, especially patients who are pursuing lifestyle measures in their healing, LDN is my first-line recommendation at this point.

Is LDN Safe?

There are well-designed small trials demonstrating clinical effect and mechanism of action. Available evidence suggests that LDN is a safe medication, and naltrexone itself has a long safety record. While there are no large long-term randomized controlled trials of LDN, I suspect that won’t change because it’s a generic drug and there is no profit incentive to pursue large clinical trials.

Are There Common Side Effects?

The most common side effects of LDN appear to get better when you stop the medication. Issues that I’ve seen in my practice are similar to what is shown in the available research. That includes vivid dreams, insomnia, increased pain, sleepiness, headache, abdominal discomfort, and nausea. Some people decide not to continue it because of side effects.

Conclusion

LDN is a relatively safe, non-typical medication that helps many people with fibromyalgia. The risk/benefit is pretty good compared to the other medications that get used for fibromyalgia. In contrast to typical pain meds, it has minimal likelihood of side-effects like sleepy, groggy, zombie feeling that often happens with Lyrica or Gabapentin. LDN has the advantage of often addressing multiple fibromyalgia symptoms, including pain, irritable bowel, and fatigue. However, because it is ‘off label’, many doctors don’t know about it. So you might have to do some effort to find someone to prescribe it locally. There are some doctors who are willing to prescribe by virtual visit. To find a local doctor who provides it, you may check out the provider directory at the LDN Research Trust website, or  feel free to contact my office.
