Low Dose Naltrexone (LDN): A Guide to Its Uses and Benefits
Low Dose Naltrexone, commonly known as LDN, is an innovative treatment approach that uses a much smaller dose of the FDA-approved medication Naltrexone. While traditionally used for opioid and alcohol dependence at higher doses, LDN has gained significant attention for its immune-modulating and anti-inflammatory properties. Patients and healthcare providers are increasingly exploring its benefits for a range of chronic conditions.
This guide provides comprehensive information on Low Dose Naltrexone, including its mechanism of action, the conditions it may help, and what to expect from treatment.
The Benefits of Low Dose Naltrexone
Patients taking LDN have reported a wide array of benefits, primarily related to reduced inflammation, pain relief, and improved overall well-being. It is most commonly explored for the following conditions:
Autoimmune Diseases
One of the most well-known applications of LDN is for autoimmune conditions. By calming an overactive immune system, LDN may help reduce symptoms associated with:
- Hashimoto's Thyroiditis
- Crohn's Disease
- Multiple Sclerosis (MS)
- Rheumatoid Arthritis
- Psoriasis
Chronic Pain Conditions
The endorphin-boosting and anti-inflammatory benefits of LDN make it a valuable option for managing chronic pain. It is often considered for:
- Fibromyalgia
- Complex Regional Pain Syndrome (CRPS)
- Neuropathic Pain
Other Potential Benefits
Research and clinical reports suggest LDN may also offer benefits for:
- Chronic Fatigue Syndrome (ME/CFS)
- Long COVID symptoms
- Certain dermatological conditions
- Mental health, including anxiety and depression, due to its effect on endorphins.
LDN Dosage and Administration
The appropriate dosage of Low Dose Naltrexone is crucial for its effectiveness and is significantly lower than the standard 50mg dose used for addiction.
- Typical Starting Dose: Most practitioners recommend starting with 0.5mg-1.5 mg taken at bedtime. This conservative approach allows patients to assess tolerance and identify any initial side effects.
- Titration: Gradual dosage increases occur every 2-4 weeks, typically advancing from 1.5 mg to 3 mg, then to 4.5 mg if needed. Some patients find their optimal dosage at 3 mg, while others require the full 4.5 mg dose.
- Administration: LDN is usually taken orally at bedtime. Taking it at night is thought to maximize the body's natural endorphin production cycle.
Special Dosage Considerations
Pediatric dosage requires careful calculation based on body weight, typically starting at 0.5 mg and adjusting according to response. Patients with severe autoimmune conditions may benefit from ultra-low starting doses of 0.5-1 mg to prevent initial symptom flares
It is essential to work with a healthcare provider experienced in LDN therapy to determine the correct dosage for your specific needs. As LDN is not commercially available in low-dose forms, it must be prepared by a compounding pharmacy.
Potential Side Effects of LDN
Side effects associated with Low Dose Naltrexone are generally mild and transient, particularly when proper dosage protocols are followed. Understanding potential side effects helps patients and healthcare providers make informed treatment decisions.
Common Side Effects
- Sleep-Related Side Effects: Approximately 15-20% of patients experience vivid dreams or mild sleep disturbances during the first few weeks of treatment. These side effects typically resolve as the body adjusts to the medication.
- Gastrointestinal Side Effects: Mild nausea, occasional stomach upset, or changes in appetite may occur initially. Taking LDN with a small amount of food can minimize these side effects.
- Energy Level Changes: Some patients report initial fatigue or conversely, mild restlessness. These side effects usually normalize within 2-4 weeks of consistent use.
Managing and Minimizing Side Effects
Starting with lower doses significantly reduces the likelihood of experiencing side effects. Patients who experience persistent side effects may benefit from dosage adjustments or timing modifications under medical supervision.
Most side effects are dose-dependent and reversible. Patients experiencing concerning side effects should consult their healthcare provider before discontinuing treatment, as dosage modifications often resolve issues while maintaining therapeutic benefits.
Important Considerations
- Opioid Use: LDN should not be taken with opioid pain medications, as it can precipitate sudden opioid withdrawal.
- Thyroid Medication: Patients with Hashimoto's may need to adjust their thyroid hormone dosage, as LDN can improve thyroid function.
Always discuss your full medical history and current medications with your provider before starting LDN to minimize the risk of side effects.
How It Works: The Unique Mechanism of LDN
Understanding how it works is key to appreciating LDN's potential. Naltrexone, an opioid antagonist, temporarily blocks opioid receptors in the brain and throughout the body. When taken in a low dose, this blockade is brief, typically lasting only a few hours.
This temporary blockade triggers a rebound effect in the body, leading to:
- Increased Endorphin Production: The body compensates by upregulating the production of endorphins, our natural "feel-good" chemicals that are crucial for pain management and a sense of well-being.
- Immune System Modulation: LDN is believed to reduce inflammation by modulating the immune system. It may decrease pro-inflammatory cytokines and regulate immune cells like T and B lymphocytes.
This dual action on endorphin levels and immune function is what makes LDN a promising therapy for various autoimmune and inflammatory disorders.

LDN requires gradual titration to minimize side effects. Always take at bedtime as it interacts with your natural circadian rhythms.
Two starting options:
- 0.5 mg capsules: Start with 1 capsule, increase by 1 every two weeks to reach 3.0 mg, then switch to 1.5 mg capsules to reach 4.5 mg
- 1.5 mg capsules: Start with 1 capsule, increase by 1 every 10 days until reaching 4.5 mg
Your Craft Telemedicine specialist will determine the best approach for your specific needs and help you find your optimal "sweet spot" dose.
LDN temporarily blocks opioid receptors in your brain and immune system for about 4-6 hours. This brief blockade triggers your body to produce more endorphins and opioid receptors, creating a rebound effect that:
- Modulates immune system function
- Reduces chronic inflammation
- Increases natural endorphin production
- Restores immune system balance
The low dosage is crucial—higher doses block receptors too aggressively, but low doses create the therapeutic rebound effect.
Primary benefits include:
- Immune system balance - especially helpful for autoimmune conditions
- Improved energy and mood - through increased endorphin production
- Reduced pain and inflammation - particularly for fibromyalgia and chronic fatigue
- Better sleep quality - due to neurotransmitter balance improvements
These benefits are supported by growing clinical research and patient reports, though LDN is used off-label for these conditions.
LDN is prescribed in microdoses from 0.5-4.5 mg daily:
- Starting dose: 0.5 mg or 1.5 mg
- Titration: Increases every 10-14 days based on tolerance
- Target dose: Often 4.5 mg, though some patients do better at lower doses
Never adjust your dosage without guidance from your Craft Telemedicine provider, as improper dosing can reduce effectiveness or increase side effects.
Yes, LDN is generally safe and may actually support immune function in immunocompromised individuals. Research shows people with chronic infections or autoimmune conditions often have low endorphin levels that LDN can help restore.
LDN boosts internal endorphin activity without overstimulating the immune system, making it a promising therapy for those with weakened immunity.
Common mild side effects:
- Vivid dreams
- Headaches
- Temporary sleep disturbances
- Mild anxiety or restlessness
Management strategies:
- Slower titration schedule
- Lower daily dose (switch to 0.5 mg capsules)
- Morning dosing instead of bedtime
- Alternate-day dosing temporarily
Most side effects are temporary and resolve with proper adjustments. Your Craft Telemedicine specialist can help customize your protocol.
Do not use if you have:
- Current opioid medication use (morphine, oxycodone, fentanyl)
- Severe liver or kidney disease
- Certain psychiatric disorders (schizophrenia)
Use caution with:
- Lyme disease or chronic infections
- Multiple chemical sensitivities
- Mold exposure illness
- Mast Cell Activation Syndrome (MCAS)
- Ehlers-Danlos Syndrome (EDS)
- Thyroid medication use (requires monitoring)
Several adjustments can help:
- Reduce current dose
- Switch to lower-strength capsules
- Change timing (morning vs. bedtime)
- Slow down titration schedule
- Try alternate-day dosing
Everyone metabolizes LDN differently. Your Craft Telemedicine provider can create a personalized approach if you're experiencing tolerance issues.
Active cancer patients should consult with integrative oncology specialists. Many general LDN providers, including Craft Telemedicine, may have limitations prescribing to patients with active cancer due to clinical and regulatory considerations.
Your provider will discuss the best approach for your specific situation.
Naltrexone is FDA-approved at higher doses for addiction treatment. However, LDN has not gone through the FDA approval process to be dispensed at lower dos
LDN is prescribed off-label (standard legal practice) for conditions like:
- Hashimoto's thyroiditis
- Crohn's disease
- Multiple sclerosis
- Chronic fatigue syndrome
