There is a medication that costs almost nothing, has a minimal side effect profile, has decades of published research behind it, and can make chemotherapy work harder.
Most oncologists have never mentioned it to their patients.
It’s called low-dose naltrexone — LDN.
Full-dose naltrexone (50mg) is used to treat opioid and alcohol addiction. At micro doses of 0.5 to 4.5mg, it does something completely different. It temporarily blocks opioid receptors, which triggers the body to produce more of its own endorphins and ramp up immune function — including natural killer cell activity that directly targets cancer cells.
Dr. Bernard Bihari treated 450 cancer patients with LDN. 270 of them had significant tumor reduction of 75% or more.
It has been shown to sensitize platinum-based chemotherapy, gemcitabine, and cyclophosphamide — meaning it can make drugs already in your protocol work harder with no added toxicity.
The only real contraindication is concurrent narcotic pain medication. Because LDN has a short half-life of about 6 hours, it can be paused quickly if acute pain management is needed.
This is not fringe. This is not experimental. This is a tool that integrative oncologists have been using for years — for adults and children — while conventional oncology has largely looked the other way.
If you are on a cancer journey — or supporting someone who is — ask your integrative practitioner about LDN. Ask about a compounding pharmacy prescription. Start at 0.5mg and titrate slowly. Early vivid dreams are normal and almost always resolve.
You deserve to know every tool available to you.
Save this. Share it with someone who needs it.
