Our evidence-based Low Dose Naltrexone protocols offer new hope for conditions that have been difficult to manage with conventional treatments alone.

What is Low Dose Naltrexone?
Low Dose Naltrexone (LDN) represents a groundbreaking approach to treating autoimmune diseases, chronic pain syndromes, and inflammatory conditions. Originally approved by the FDA at higher doses (50-100mg) for opioid and alcohol addiction, naltrexone at much lower doses (typically 1.5-4.5mg) produces entirely different therapeutic effects. At these low doses, LDN works primarily by temporarily blocking opioid receptors for a few hours, which paradoxically triggers the body to increase production of endorphins and enkephalins—the body's natural pain relievers and immune modulators. This brief blockade creates a rebound effect that enhances immune function, reduces inflammation, and promotes tissue healing.
The mechanism of action for LDN extends beyond opioid receptor modulation. Research indicates that low dose naltrexone also antagonizes Toll-like Receptor 4 (TLR4) on microglia and macrophages, which are key players in neuroinflammation and systemic inflammation. By modulating these immune pathways, LDN can reduce the production of pro-inflammatory cytokines while promoting anti-inflammatory responses. This makes it particularly valuable for conditions where the immune system has become overactive or dysregulated, including multiple sclerosis, Crohn's disease, rheumatoid arthritis, fibromyalgia, chronic fatigue syndrome, Hashimoto's thyroiditis, and numerous other autoimmune and inflammatory conditions.
What makes LDN especially appealing is its remarkable safety profile and minimal side effects compared to many conventional immunosuppressive or anti-inflammatory medications. Because it works with the body's natural healing systems rather than suppressing immune function, patients typically experience few adverse effects. The growing body of clinical evidence and patient testimonials has made LDN an increasingly recognized option for individuals seeking alternatives to traditional therapies or looking to complement their existing treatment regimens. At Premier Internal Medicine, we have extensive experience prescribing and monitoring LDN therapy, ensuring optimal dosing and integration with your comprehensive care plan.

What to Expect with LDN Therapy
First Visit & Prescription
Comprehensive consultation to review your medical history, current conditions, and treatment goals. We'll discuss LDN's mechanism of action, potential benefits for your specific situation, and answer all your questions. You'll receive your customized prescription and guidance on working with a compounding pharmacy. We provide detailed instructions on timing, storage, and what to monitor.
Weeks 2-4: Initial Phase
Starting on your low initial dose, typically 1.5mg at bedtime. Some patients experience vivid dreams initially as the body adjusts—this is normal and usually resolves within a week or two. We check in to assess tolerability and begin tracking symptom changes. Most side effects are minimal and transient. Keep a symptom journal to track changes in pain, energy, mood, and disease-specific symptoms.
Months 1-3: Dose Optimization
Gradual dose adjustments to find your optimal therapeutic level. Many patients begin experiencing noticeable improvements during this period—reduced pain, better energy, decreased inflammation, or improvement in disease-specific markers. Follow-up appointments every 4-6 weeks to assess progress, adjust dosing, and address any questions. This is when we fine-tune your protocol for maximum benefit.
Long-term Management
Once you've reached your optimal dose, most patients continue LDN therapy long-term as part of their overall health strategy. Benefits often continue to accrue over 6-12 months. Ongoing monitoring every 3-6 months ensures continued effectiveness and allows us to adjust your comprehensive care plan as your health evolves. Many patients report sustained improvement in quality of life, reduced need for other medications, and better overall disease control.
Evidence-Based LDN Treatment Protocol
Our Low Dose Naltrexone program begins with a thorough medical evaluation to ensure LDN is appropriate and safe for your specific situation. We carefully review any medications you're currently taking, particularly opioid medications which are contraindicated with LDN therapy. For patients with autoimmune conditions, we assess disease activity, inflammation markers, and current treatment efficacy to establish baseline measurements for tracking progress.
Dosing typically starts conservatively at 1.5mg taken at bedtime, as this timing optimizes the endorphin rebound effect. We gradually increase the dose every 2-4 weeks based on your response, usually reaching a therapeutic dose between 3mg and 4.5mg. Some conditions may respond to lower doses, while others may benefit from slightly higher amounts. Because LDN must be compounded at these low doses, we work with reputable compounding pharmacies that use high-quality naltrexone and appropriate fillers to ensure consistent, reliable medication.
Throughout your treatment, we monitor both subjective improvements in symptoms and objective markers when applicable. Many patients begin noticing benefits within 4-8 weeks, though some conditions may require 3-6 months for optimal response. We integrate LDN therapy with other appropriate treatments, nutritional support, lifestyle modifications, and conventional medications as needed. Our goal is to enhance your body's natural healing capacity while providing comprehensive, integrative care that addresses the root causes of inflammation and immune dysfunction.
Common Questions About Low Dose Naltrexone
How is Low Dose Naltrexone different from regular naltrexone?
Regular naltrexone is prescribed at doses of 50-100mg for treating opioid and alcohol addiction by fully blocking opioid receptors. Low Dose Naltrexone uses just 1.5-4.5mg—a tiny fraction of the standard dose. At these low doses, naltrexone produces completely different effects: instead of blocking addiction pathways, it briefly and partially blocks opioid receptors for just a few hours, triggering a rebound increase in endorphin production and modulating immune function. This paradoxical mechanism makes LDN valuable for autoimmune diseases, chronic pain, and inflammation rather than addiction treatment. The two applications use the same medication but leverage entirely different pharmacological effects.
What conditions respond best to LDN therapy?
LDN has shown particular promise for autoimmune conditions including multiple sclerosis, rheumatoid arthritis, Crohn's disease, ulcerative colitis, Hashimoto's thyroiditis, and lupus. It's also effective for chronic pain syndromes like fibromyalgia, complex regional pain syndrome, and neuropathic pain. Many patients with chronic fatigue syndrome, Lyme disease, and post-infectious syndromes experience significant benefit. Inflammatory skin conditions like psoriasis, mental health conditions with inflammatory components, and even some cancer patients using it as adjunctive immune support have reported improvements. Response varies by individual, but conditions involving immune dysregulation and chronic inflammation tend to respond most favorably.
What are the side effects of Low Dose Naltrexone?
LDN is remarkably well-tolerated with a very favorable safety profile. The most common initial side effect is vivid dreams or sleep disturbances, which typically resolve within 1-2 weeks as your body adjusts. A small percentage of patients experience mild, temporary headaches or slight nausea when first starting. These effects are usually transient and can be managed by adjusting dose timing or starting at an even lower dose. Unlike many immunosuppressive or anti-inflammatory medications, LDN doesn't cause organ toxicity, doesn't suppress immune function, and has minimal drug interactions. Most patients experience no side effects at all and take LDN safely for years.
How long does it take to see results from LDN?
Response time varies depending on the condition being treated and individual factors. Some patients notice improvements in energy, mood, or pain levels within 2-4 weeks of starting therapy. More substantial changes in autoimmune markers, inflammation levels, or disease activity typically become apparent at 2-3 months. For some conditions, particularly complex autoimmune diseases, optimal benefits may take 6-12 months to fully manifest. It's important to be patient and consistent with therapy, as LDN works by gradually modulating immune function rather than providing immediate symptom suppression. We track your progress closely and adjust treatment as needed to optimize your response.
Can I take LDN with my other medications?
LDN has very few drug interactions and can usually be safely combined with most medications. However, it cannot be taken with opioid pain medications (like hydrocodone, oxycodone, morphine, or tramadol) as it will block their effectiveness. Patients must be completely off opioids for at least 7-10 days before starting LDN. It's generally safe with immunosuppressants, biologics, thyroid medications, antidepressants, and most other common drugs. We carefully review your complete medication list during your consultation to identify any potential interactions. Many patients find that as LDN becomes effective, they're able to reduce other medications under our supervision. Always inform all your healthcare providers that you're taking LDN.
