Exploring Low Dose Naltrexone: Why Prescribers Choose LDN for Patients
In the quest for more effective management of chronic pain, inflammation, and autoimmune conditions, the medical community continually seeks innovative medication and alternatives to the commercially available drugs that don’t always work for everyone.
One such option gaining attention is Low Dose Naltrexone (LDN). Health Dimensions Clinical Pharmacy (HDRx), Michigan’s trusted compounding pharmacy, is at the forefront of providing custom-compounded LDN, aligning with the latest advancements and the highest standards.
Understanding Low Dose Naltrexone
Naltrexone, initially approved by the FDA in the 1980s for opioid addiction, has found a new application at lower doses. When administered in low doses, it is increasingly prescribed for its potential in managing chronic pain, autoimmune diseases, and inflammation.
It’s noted that individuals with autoimmune diseases and chronic pain often exhibit lower levels of endorphins, particularly Met-enkephalin (also known as opioid growth factor or OGF), which is vital for immune modulation.
Opioid receptors, located in the nervous system, gastrointestinal tract, and on lymphocytes, interact with these endorphins. Low Dose Naltrexone (LDN) works by temporarily blocking these receptors, leading to a rebound effect that not only boosts endorphin levels, including OGF, but also increases the production of OGF receptors.
↑ Endorphins =
↓ Pain/Autoimmune/Inflammation

This mechanism is why many prescribers recommend LDN for patients, especially those with autoimmune conditions and chronic pain, as a way to naturally enhance the body’s immune response and promote better health.
Opioid Growth Factor (OGF) Explained
- Restoration of OGF Levels in Autoimmune Conditions: Some studies suggest that individuals with autoimmune diseases, like Multiple Sclerosis, may exhibit lower levels of OGF, and LDN therapy has been shown to restore these levels. LDN’s action of transiently blocking opioid receptors, including the OGF receptor, is believed to trigger a compensatory increase in OGF production, thereby helping to bring these levels back into balance.
- Inhibition of Cell Proliferation: OGF interacts with the OGF receptor (OGFr) to suppress cell proliferation. LDN’s mechanism of action involves a temporary blockage of the OGF receptor, leading to an upregulation of OGF and its receptors. This, in turn, can help regulate abnormal cell growth seen in certain cancers and autoimmune conditions.
- Modulation of Inflammatory Response: OGF influences the production of inflammatory cytokines. Higher OGF levels, induced by LDN, can lead to decreased production of pro-inflammatory cytokines and increased production of anti-inflammatory cytokines, creating a more balanced immune response and potentially reducing inflammation in conditions like Fibromyalgia.
- Central Nervous System (CNS) Effects: Studies suggest that LDN’s actions, potentially through OGF, may influence the functioning of glial cells, particularly microglia, which are key players in neuroinflammation and conditions like Multiple Sclerosis and Fibromyalgia. LDN’s modulation of glial cells, possibly via OGF signaling and other mechanisms, may contribute to the pain-relieving and neuroprotective effects observed in some patients.
- It is important to note that research on LDN, especially in the context of OGF, is still ongoing, and more robust studies are needed to fully understand its effects.
- While evidence suggests a link between OGF, LDN, and improvements in certain autoimmune and inflammatory conditions, the precise mechanisms can be complex and may involve multiple pathways and interactions within the body.
The Research Behind Low Dose Naltrextone (LDN)
A growing body of research from peer-reviewed medical journals suggests that LDN holds great potential in a variety of health conditions.
STUDY:
Low-dose naltrexone (LDN): A promising treatment in immune-related diseases and cancer therapy
Journal: International Immunopharmacology
Takeaways:
- LDN could broadly stimulate immune cells by blocking the binding of endogenous opioids and opioid receptors.
- LDN may reduce the in vivo activity of inducible nitric oxide synthase in patients and reduce inflammation.
- LDN showed intermittent opioid receptor blockade and upregulated the expression of OGF and OGFr, inhibiting tumor progression in a cytotoxic manner by reducing DNA synthesis and angiogenesis rather than altering cell survival
“LDN can act as an immunomodulator in multiple autoimmune diseases and malignant tumors as well as alleviate the symptoms of some mental disorders. The results of increasing studies indicate that LDN exerts its immunoregulatory activity by binding to opioid receptors in or on immune cells and tumor cells. These new discoveries indicate that LDN may become a promising immunomodulatory agent in the therapy for cancer and many immune-related diseases.”

The use of low-dose naltrexone (LDN) as a novel anti-inflammatory treatment for chronic pain
Journal: Clinical Rheumatology
Takeaways:
It is via the non-opioid antagonist path that LDN is thought to exert its anti-inflammatory effects
LDN has been reported to reduce self-reported pain and objective markers of inflammation and disease severity
LDN yields low reported incidence of adverse side effects
These studies, among others, underscore the evolving understanding and application of LDN in addressing a variety of conditions.
What is LDN Prescribed for?
Here are some common conditions for which LDN is often prescribed:
- Chronic Pain: Used to manage various types of chronic pain, including fibromyalgia and nerve-related pain.
- Autoimmune Disorders: Conditions such as multiple sclerosis, rheumatoid arthritis, and Crohn’s disease have seen an increasing interest in the use of LDN.
- Inflammatory Conditions: LDN is prescribed to help manage inflammation-related symptoms in certain medical conditions.
- Mood Disorders: Some practitioners explore the use of LDN in addressing mood disorders, including depression and anxiety.
- Dermatological Conditions: Certain skin conditions, which may have an autoimmune or inflammatory component, are sometimes addressed with LDN.
- Cancer: While not a primary medication, some healthcare providers prescribe LDN as part of an integrative approach to cancer care.
Other health conditions LDN is prescribed for:
– Multiple Sclerosis

Why Proper Titration of Low Dose Naltrexone (LDN) Matters
When prescribing Low Dose Naltrexone (LDN), proper titration is essential to help patients achieve therapeutic benefits while minimizing potential side effects like vivid dreams, nausea, or headaches. Because patient responses to LDN can vary, a gradual increase allows the body to adapt while ensuring optimal receptor response and long-term tolerance. This individualized approach supports better outcomes—especially in patients managing chronic pain, inflammation, or autoimmune conditions.
