Low Dose Naltrexone (LDN) Therapy
at Vance Medical
Low Dose Naltrexone is one of the most underutilized — and misunderstood — treatments in modern medicine. Most physicians know naltrexone only as a medication for opioid and alcohol addiction. But at a fraction of its standard dose, naltrexone produces something remarkable: a powerful, natural boost to the immune system and a reduction in chronic pain and inflammation that has helped patients with conditions ranging from fibromyalgia to autoimmune disease to cancer.
At Vance Medical, we have been prescribing LDN for years. For many of our chronic illness patients, it has been a turning point — the treatment that finally moved the needle when nothing else would.
What Is Low Dose Naltrexone?
Naltrexone was developed in the 1980s to treat heroin addiction. It works by blocking opioid receptors, preventing the euphoric effect of opiates. A researcher named Dr. Bihari discovered something unexpected: at very low doses — less than 10% of the standard therapeutic dose — naltrexone didn’t help addiction, but it did help his HIV patients stay healthier and resist illness.
Further research revealed why: at low doses, LDN temporarily blocks opioid receptors for only 2–4 hours. During that window, the body responds by producing more of its own natural endorphins. When the naltrexone clears, this elevated endorphin level becomes available — and endorphins do far more than just relieve pain. They are critical modulators of the immune system, helping the body fight what it should fight (infections and disease) while calming inappropriate immune responses (autoimmune conditions).
How LDN Works in the Body
Endorphin Upregulation
By briefly blocking opioid receptors, LDN tricks the body into producing a larger supply of endorphins. This natural endorphin surge reduces chronic pain, improves mood, and supports immune function — all without dependence or the side effects of prescription painkillers.
Central Nervous System Anti-Inflammatory Effect
At the central nervous system level, LDN acts as a powerful anti-inflammatory agent. It modulates microglia — the immune cells of the brain — reducing neuroinflammation that contributes to conditions including fibromyalgia, brain fog, depression, and chronic fatigue.
Immune System Regulation
LDN helps calibrate the immune system — boosting its response when it is underperforming (as in chronic infections or cancer) and calming it when it is overreacting (as in autoimmune conditions). This dual modulation effect makes LDN uniquely versatile across a wide range of conditions.

Getting Started with LDN at Vance Medical
Evaluation & Prescription
LDN requires a prescription and a medical evaluation. Dr. Vance reviews your health history, current medications, and specific condition to determine whether LDN is appropriate for you and what starting dose makes sense. Because LDN is highly individualized — the dose that works best varies from patient to patient — we begin conservatively and titrate upward.
Compounding & Our In-House Pharmacy
While Vance Medical does have a limited in-house pharmacy, LDN is not available in standard pharmaceutical doses and must be custom-compounded at a compounding pharmacy.
Titration & Monitoring
Most patients start at a low dose and gradually increase over several weeks until the optimal therapeutic dose is identified. ‘Too low’ typically produces no effect; ‘just right’ can produce remarkable improvement; ‘too high’ may temporarily increase symptoms. Dr. Vance works closely with each patient to find their individual sweet spot.
What to Expect When Starting LDN
Weeks 1–2
Weeks 3–6
Weeks 6–12

Frequently Asked Questions
Is LDN covered by insurance?
Because LDN must be compounded and is used off-label for most conditions, it is typically not covered by insurance. However, the cost is generally quite low — often $30–$60 per month — making it one of the most affordable integrative treatments available.
Can I take LDN alongside other medications?
LDN is generally very well tolerated and compatible with most medications. Important exceptions: LDN should not be taken with full-dose opioid medications, as it will block their effect. Always disclose all medications to Dr. Vance before starting LDN.
How long will I need to take LDN?
This depends on your condition. Some patients take LDN indefinitely as an ongoing immune support therapy. Others, once their underlying condition is addressed, are able to taper off. Dr. Vance will discuss long-term management with you as you progress.
How do I know if LDN is working?
Most patients track improvement in their primary symptoms — pain levels, fatigue, immune function, flare frequency, mood. Dr. Vance monitors your response at follow-up visits and adjusts the dose accordingly.
