Low-Dose Naltrexone Therapy. Prescribed for Inflammation, Not Addiction
Naltrexone is FDA-approved at 50mg for addiction. At 0.5–4.5mg, it works through a completely different mechanism, one that targets immune dysregulation and systemic inflammation. That off-label use requires a licensed provider, a clinical evaluation, and labs. Telehealth LDN therapy across CO, AZ, ID, ME, MT, NH, NM, WA, and WY.
What Low-Dose Naltrexone Actually Does in the Body
At standard doses, naltrexone blocks opioid receptors to prevent the euphoric effect of opioids. At a fraction of that dose, typically between 0.5mg and 4.5mg, something different happens. The blockade is transient, lasting only a few hours. During that window, your body compensates by upregulating its own endorphin and enkephalin production. The downstream effect is a recalibration of immune signaling: specifically, reduced activation of glial cells in the central nervous system and antagonism of toll-like receptor 4 (TLR4), a key driver of neuroinflammation and systemic inflammatory burden.
That mechanism is why LDN has been studied in conditions characterized by immune dysregulation, not because it suppresses immune function, but because it modulates it. The difference matters. At Steel City, LDN is prescribed after a clinical intake that reviews your inflammatory markers, medication list, and health history. We monitor hs-CRP over time because we want objective data, not just symptom reports.
What are the benefits of LDN?
Reduced systemic inflammation: Hs-CRP is your primary objective marker. Most patients don't see meaningful reductions before the 8-week mark, and some take 3–6 months of consistent dosing to show measurable change. This is a long-game therapy by design; titration is slow, and so is the evidence accumulating in your labs.
Immune modulation for autoimmune burden: LDN's effect on the Th1/Th2 immune balance underlies its use in patients with autoimmune conditions. It doesn't suppress immune response the way biologics or steroids do. It retrains the signaling pattern.
Pain reduction through neuroinflammatory pathways: Glial cell activation in the central nervous system amplifies pain signaling. LDN reduces microglial activation, which is why patients with chronic widespread pain and fibromyalgia-pattern symptoms are frequently candidates. The mechanism is neurological, not analgesic.
Cognitive clarity and reduced brain fog: Chronic neuroinflammation has downstream effects on cognitive performance. Patients with elevated inflammatory burden often report brain fog as a primary complaint. When inflammation is the driver, addressing it at the TLR4 level has cognitive effects that aren't separate from the anti-inflammatory effect; they're the same mechanism, different symptom.
Sleep normalization: LDN is dosed at bedtime during the titration phase. Sleep disturbance is a common early side effect as the dose increases. Once a therapeutic dose is established, many patients report improved sleep quality, though this is a secondary outcome rather than the primary therapeutic target.
How Low-Dose Naltrexone Works Here
Step 1: Clinical intake and medication review: LDN has one absolute contraindication: opioid medications. The intake isn't a formality. We review your full medication list, health history, and inflammatory picture before prescribing anything. Patients currently using opioids are not candidates.
Step 2: Baseline labs: CMP and hs-CRP are required before initiation. The CMP gives us a metabolic baseline; hs-CRP is the inflammatory marker we'll track over time to assess whether the therapy is working objectively. Labs are ordered through our clinic and run through our designated lab network.
Step 3: Telehealth consultation: A 30-minute provider visit to review your intake, labs, and clinical suitability. If LDN is appropriate, your prescription is initiated at this visit. If you're an existing TRT or HRT patient, the consultation fee is waived initially.
Step 4: Titration, slower is better: LDN is not started at the therapeutic dose. Typical initiation is 0.5mg, titrating upward based on your response. Moving too fast increases the likelihood of vivid dreams, sleep disruption, and transient headaches. We pace the titration based on your tolerance rather than a fixed schedule.
Step 5: Ongoing monitoring: Follow-up labs at 8 weeks, then every 3–6 months based on your clinical response. We're tracking hs-CRP against baseline to confirm the therapy is producing an objective result. Refills are not authorized if labs are overdue.

The Clinical Guide to Peptide Therapy
Most of what's written about peptides online is either written by people selling them without a prescription or by people who've never prescribed them. This guide is neither.
It covers how peptides function as biological signaling molecules, which therapeutic categories exist and what mechanisms they work through, what the legal compounding pathway actually looks like under 503A, and what separates a clinically prescribed protocol from what's sold online under a research-use-only label.
You'll also find transparent pricing information, an explanation of what the intake process looks like at Steel City, and answers to the questions most patients bring to their first visit.

FAQs
Isn't naltrexone an addiction medication?
At 50mg, yes, it's FDA-approved to block the euphoric effect of opioids and alcohol. At 1.5–4.5mg, the pharmacology is entirely different. The blockade is short-lived, triggering a compensatory increase in your body's endorphin production. That rebound effect, repeated nightly, produces immune-modulating changes that aren't present at higher doses, the same drug, a fundamentally different mechanism. We're prescribing off-label at low doses, and we'll document the clinical rationale for every prescription we write.
Can I take LDN if I'm on opioid pain medications?
No. This is an absolute contraindication, not a precaution. LDN and opioids taken together can precipitate acute opioid withdrawal, which can require hospitalization. If you are currently prescribed any opioid, Oxycodone, Hydrocodone, Tramadol, Buprenorphine, Codeine, or any related compound, or are ever prescribed an opioid for an acute injury or surgery while on LDN, you must notify us immediately and suspend the therapy.
Is this FDA-approved?
Naltrexone is FDA-approved at 50mg for opioid and alcohol use disorder. Its use at low doses (0.5–4.5mg) for immune modulation and inflammation is off-label. Off-label prescribing is legal, common, and clinically appropriate when the provider has a documented rationale and the patient has given informed consent. We disclose this clearly at intake. The compound itself is not experimental and is not sourced from a gray-market supplier; it is pharmacy-compounded naltrexone at a specific low dose, prescribed by name to you, dispensed under pharmacy regulations.
How long before I see results?
Titration to a therapeutic dose typically takes 4–8 weeks, depending on how you tolerate dose increases. Objective improvement in hs-CRP, the inflammatory marker we track, often isn't visible before the 3-month mark. Some patients notice symptomatic changes earlier. The lab data tends to lag the subjective experience by 4–8 weeks. If your hs-CRP hasn't moved after 6 months of consistent therapeutic dosing, we reassess the protocol rather than continuing indefinitely.
I'm already on TRT, GLP-1, or peptide therapy. Does LDN fit?
LDN is frequently used as an adjunct to other protocols. Systemic inflammation is a common driver of suboptimal hormone response; patients on TRT with elevated hs-CRP often see their optimization outcomes improve when the inflammatory burden is addressed. The same logic applies to GLP-1 therapy, where metabolic inflammation can blunt the medication's full effect
What does the medical management subscription cover?
The $49 every-four-weeks fee covers clinical oversight, provider review, dose titration, lab trend analysis, opioid screening compliance, and HIPAA-compliant secure messaging. Naltrexone medication is billed separately at pharmacy pass-through rates. Refills are not authorized if your subscription has lapsed or your required labs are overdue.
