Episode 39: LDN with Dr. Thomas Cowan

What Is Low Dose Naltrexone?

Naltrexone is a medication that blocks opiate receptors in the brain. It is most commonly used at a high dose (50 mg) to treat heroine addiction. In the 1980’s and 90’s, researchers discovered that using it at a very low dose (1-4.5 mg) helped people with autoimmune disease without the high cost or side effects of conventional autoimmune medication. Today, we’re going to learn more about this nontraditional autoimmune medication – how it works and how to find a doctor who prescribes it. Our guest is Dr. Thomas Cowan, a medical doctor in San Francisco who has used Low Dose Naltrexone (LDN) for many years as part of his autoimmune patient treatment plan.

Show Notes

• Intro (0:00)
• Thank You to our Podcast Sponsor – Paleo on the Go (2:02)
  • A frozen meal delivery service, they have a large menu of items for the paleo autoimmune protocol (AIP).
  • Use the code PHOENIX for 10% off your first order.
• Meet Dr. Thomas Cowan (2:41)
  • Dr. Cowan is a medical doctor in San Francisco who uses LDN with his patients with autoimmune disease.
  • He is also the author of 2 books: The Fourfold Path to Healing and The Nourishing Traditions Book of Baby and Childcare.
  • He went to medical school at Michigan State University but always knew he wanted to practice medicine in a non-conventional way. He started practicing Anthroposophical Medicine in the 80’s and 90’s. Now, he doesn’t define his practice under any specific philosophy other than working with the body’s natural wisdom in helping his patients heal.
• How LDN Affects Autoimmune Disease (11:08)
  • Food antigens like gluten and casein, when absorbed into our bloodstream through leaky gut, become toxic opiates that interfere with our immune response.
  • Low Dose Naltrexone replaces these toxic opiates with healthy ones instead, helping the immune system rebalance. It does this by temporarily blocking opiate receptors in the body for a few hours while you’re sleeping. During that time, the body tries to overcome the block by releasing extra opiates called endorphins.
  • Endorphins run the immune system – our immune cells, and the cells of our gut and brain, have a high number of endorphin receptors.  People with autoimmune disease often have a combination of low endorphins and high toxic opiates.
• Why LDN Works for Some People and Not for Others (16:51)
  • Results with LDN vary – everything from having no effect at all, to mild improvements, to achieving autoimmune disease remission. Dr. Cowan has seen this range in his practice as well. It’s worth trying because if it does work, it’s an inexpensive medication ($20-60/month) with minimal side effects.
  • LDN has been mentioned on two prior podcasts as being very effective for two of my guests: Emily who has rheumatoid arthritis talked about her LDN success on Episode 33 , and Chelsey who has Crohn’s disease talked about her success on Episode 35. You can also see other video testimonials online through the LDN Research Trust.
  • One reason LDN may not work is if someone hasn’t changed their diet and continues to eat foods likely to turn into toxic opiates in their body (like gluten in wheat and casein in dairy).
  • In other cases, some people’s bodies might not be able to produce the extra endorphins needed.
• Finding the Right LDN Dosage (20:20)
  • The original recommended dose was 4.5 mg before bed. Now, they know that dosage needs vary between individuals from 1-4.5 mg.
  • Dr. Cowan starts his patients with 1 or 1.5 mg for 2 weeks and then asks them to report back. If there is benefit at that level, he doesn’t raise it further. If there’s no benefit, he will double the dose to 2-3 mg. They report back in 2 weeks again.  If it’s beneficial at that level, he’ll leave it there. If there’s no effect, he’ll raise it to the maximum 4.5 mg. Note: When there’s a negative effect at any level, he doesn’t have his patients continue for two weeks, but rather call him so he can lower the dose by .5 mg immediately.
  • With LDN, more is not more effective. It’s about finding the lowest beneficial dose, and effectiveness disappears at higher levels.
  • Another option with people who have side effects at the lowest dose is to take it every other day.
  • Those people who benefit from LDN will usually receive benefit as long as they continue to take it. It’s not a temporary medication, although you can take breaks from it to test if you still need it.
  • It can sometimes take 2-3 months before noticing a benefit, although it’s also possible to feel a dramatic effect the very next day.
• Potential Side Effects
  • Insomnia and bad dreams – although this is usually caused by going on too high a dose too quickly.
• Compounding Pharmacies (27:01)
  • This is an off-label use of Naltrexone medication, which means there are no tablets available at this low a dose. Instead, you need to have the medicine made through a compounding pharmacy.
  • LDN needs to be combined with fillers. You want to make sure the fillers are fast-releasing and allergen-free.
  • List of compounding pharmacies experienced with making LDN.
  • If you tried LDN and it didn’t work for you, you can try again from a different pharmacy. Sometimes that makes a difference.
• Finding an LDN-Prescribing Doctor (35:08)
  • You can ask your current doctor for a prescription, but many conventional doctors don’t believe in LDN and won’t prescribe it. If that’s the case for you, here is a list of LDN-Prescribing doctors.
  • However, Dr. Cowan recommends you find a physician who uses LDN as part of his autoimmune treatment plan and guides you in other ways as well, because LDN (independent of addressing diet, lifestyle and other factors) isn’t as effective. I have a list of Paleo Functional Practitioner Directories.
• Research Into LDN and Autoimmune Disease (38:41)
  • Update: The LDN Book was published in 2016 which summarizes all of the research. And a second volume is due to published in 2020.
  • The LDN Research Trust is funding clinical trials.
  • Clinicaltrials.gov lists both completed trials and ones that are recruiting participants.
  • Pubmed contains published research results.
  • New research: With non-autoimmune hypothryoidism, there is a developing theory of thyroid hormone resistance – where blood levels are normal yet hypothryoid symptoms are being exhibited. LDN can help with that resistance. There is also research into using LDN for anxiety and depression. All of this is summarized in The LDN Book.
• Helping Patients Make Medication Decisions (43:14)
  • As an MD, Dr. Cowan uses a combination of alternative and conventional medicine as needed for his patients with autoimmune disease. While the goal is to avoid or eliminate immunosuppressant medication and the symptoms they are suppressing, that can take time. It’s important to do that under the guidance of a doctor who specializes in reversing autoimmune disease. Trying to go off medication cold-turkey leads to autoimmune flares.
• Outro (47:11)
  • Update 2023: Dr. Cowan has retired from his clinical practice.
  • Eileen (your podcast host) is the author of multiple books, written to help people thrive with autoimmune disease. Learn more on the Books Page.
