Low-dose naltrexone (LDN) is being studied as a treatment for rheumatoid arthritis. While traditionally used for other conditions, LDN works by binding to specific receptors in the body that can help reduce inflammation - a key factor in RA symptoms. The typical dose is about 4.5 milligrams daily, which is much lower than traditional naltrexone doses.
One notable benefit is that LDN is relatively inexpensive compared to other RA treatments, typically costing around $35 per month. Important things to know about LDN:
• It must be obtained through a compounding pharmacy since it's not commercially available in low doses
• It's considered an "off-label" use, meaning it's being used differently than its original FDA approval
• It works by affecting the immune system and reducing inflammatory proteins
• More research is still needed to fully determine its effectiveness for RA
If you're interested in trying LDN, it's important to discuss this option with your rheumatologist to determine if it might be appropriate for your specific situation.
