What It Is
Low Dose Naltrexone (LDN) is an off-label use of the drug naltrexone, typically prescribed at very low doses (1.5–4.5mg) compared to its standard addiction-treatment dose. The theory is that it briefly blocks opioid receptors, causing your body to overcompensate by producing more endorphins — which in turn modulates the immune system.
Why I Tried It
I found it in a lupus Facebook group at 2am, like you do. Dozens of people swearing it changed their lives. It’s cheap. It’s been around forever. And my rheumatologist had never mentioned it, which honestly made me more curious, not less.
What Happened
I tried it for six months. The first two weeks I had vivid, unsettling dreams — a known side effect that most people say resolves. Mine did. After that, my sleep actually improved noticeably. Did my lupus symptoms improve? Honestly, hard to say. I had a relatively stable stretch during that period but I was also doing other things simultaneously. I can’t give LDN full credit.
The Verdict
Worth discussing with your doctor if you have an open-minded one. The risk profile is low, the cost is low (compounding pharmacies, roughly $30–50/month), and the anecdotal support in the autoimmune community is significant enough to pay attention to. I’m not ruling it back out.
