Gabapentin and Pregabalin Explained: Calming an Overactive Nervous System in Pain, RLS, Fibromyalgia, and Sleep

The script explains gabapentinoids (gabapentin and pregabalin) as neuromodulators that “turn down” an overexcited central nervous system seen in central sensitization/nociplastic pain syndromes, helping conditions such as neuropathic pain, restless leg syndrome (RLS), fibromyalgia, anxiety, and sleep disruption. It clarifies they don’t act on GABA receptors; instead they bind the alpha-2-delta-1 subunit on calcium channels, reducing calcium influx and release of excitatory neurotransmitters (glutamate, substance P, norepinephrine), lowering pain, restlessness, and anxiety. The script highlights guideline shifts making gabapentinoids first-line for chronic RLS due to minimal augmentation risk versus dopamine agonists, notes pregabalin’s FDA approval for fibromyalgia (gabapentin used off-label), and emphasizes improved slow-wave sleep and restorative recovery. Practical guidance includes nighttime dosing, “start low and go slow” titration, side effects, off-label use, and the need for doctor supervision.

When I started this podcast and YouTube Channel—and the book that came before it—I had my patients in mind. Office visits are short, but understanding complex, often misunderstood conditions like fibromyalgia takes time. That’s why I created this space: to offer education, validation, and hope. If you’ve been told fibromyalgia “isn’t real” or that it’s “all in your head,” know this—I see you. I believe you. This podcast aims to affirm your experience and explain the science behind it. Whether you live with fibromyalgia, care for someone who does, or are a healthcare professional looking to better support patients, you’ll find trusted, evidence-based insights here, drawn from my 29+ years as an MD.
