Low Dose Naltrexone (LDN) has gained recognition for its potential to support a range of health conditions by modulating immune function and reducing inflammation. Originally developed to treat opioid addiction at higher doses, LDN is used at a fraction of this dose to help patients with autoimmune conditions, chronic pain, and other inflammatory conditions. This unique approach has made LDN an appealing option for patients looking for immune system support without the side effects commonly associated with higher-dose medications.
At Formulate Rx, we specialize in compounding customized Low Dose Naltrexone (LDN) Capsules to meet the needs of each patient.

What is Low Dose Naltrexone (LDN)?
Low Dose Naltrexone is a repurposed form of Naltrexone, traditionally used at higher doses for addiction treatment. At much lower doses, typically between 0.5mg to 4.5mg, LDN works by temporarily blocking opioid receptors, which leads to a rebound effect of increased endorphin production and modulation of the immune response. This approach makes LDN an innovative option for individuals with conditions characterized by inflammation, immune dysregulation, or chronic pain.
How Does Low Dose Naltrexone (LDN) Work?
LDN’s effectiveness is linked to its ability to boost the body’s natural endorphin production and regulate immune system activity. By briefly blocking opioid receptors overnight, LDN creates a response in the body that increases endorphin levels and stimulates certain immune cells. These changes can reduce inflammation and support the immune system’s natural balance, providing a potential benefit for people with autoimmune and inflammatory conditions.
This mechanism allows LDN to offer a unique, low-risk option for patients seeking alternatives to traditional therapies.
Benefits of Low Dose Naltrexone (LDN) for Immune Support
LDN offers a range of potential benefits for patients with autoimmune and inflammatory conditions:
Reduced Inflammation: Many patients report improvements in symptoms related to inflammation, such as joint pain, muscle stiffness, and digestive discomfort.
Enhanced Immune Regulation: LDN is thought to help modulate the immune system, making it a promising option for autoimmune conditions.
Improved Mood and Energy Levels: By boosting endorphins, LDN may improve mood and increase energy levels, supporting overall quality of life.
Pain Relief: LDN has been used successfully in patients with chronic pain conditions, including fibromyalgia and neuropathic pain.
Minimal Side Effects: Due to its low dosing, LDN is generally well-tolerated with few side effects.
