Low-Dose Naltrexone (LDN)
At Medicap Pharmacy in Harrisonburg, VA, we prepare Low-Dose Naltrexone (LDN) as a customized prescription to meet individual needs, following their provider’s directions. LDN has gained attention for its potential role in a variety of conditions related to immune system regulation, inflammation, and chronic pain.
What Is LDN?
Naltrexone was originally FDA-approved at much higher doses (typically 50 mg) to treat opioid or alcohol dependence. At much lower doses (usually 0.5 mg to 4.5 mg), research and clinical use suggest it may have a different mechanism of action, temporarily blocking opioid receptors and prompting the body to increase production of endorphins and enkephalins, which are naturally occurring chemicals involved in immune function, pain modulation, and cell repair.
Because LDN is not commercially available in these low strengths, it must be compounded by a pharmacy.
How LDN May Work
While the exact mechanism is still being studied, LDN may:
- Temporarily block opioid receptors, leading to a rebound increase in endorphin levels.
- Modulate immune response, which may help balance overactive or underactive immune activity.
- Reduce inflammation by helping to influence certain cellular pathways.
Conditions Where LDN Is Being Studied or Used
Healthcare providers may consider LDN as part of a patient’s therapy plan for a variety of conditions, including:
- Autoimmune disorders (e.g., multiple sclerosis, Hashimoto’s thyroiditis, rheumatoid arthritis, lupus)
- Chronic pain syndromes (e.g., fibromyalgia, complex regional pain syndrome, neuropathic pain)
- Inflammatory conditions (e.g., Crohn’s disease, ulcerative colitis)
- Certain skin disorders (e.g., psoriasis, eczema)
- Thyroid disorders (especially autoimmune-related)
