Low-dose Naltrexone for Hashimoto’s Thyroiditis. A Game Changer.

Low-dose Naltrexone for Hashimoto's. A Game Changer.

Low-dose Naltrexone. Have you heard of it?

Written by Tristin Halie Fleetwood


When I was 14 I began to have severe migraines and chronic stomach issues. What I didn’t know was I would spend the next 10 years of my life seeking out over 20 medical professionals, receive 13 different diagnoses and over 30 pharmaceutical prescriptions.

In 2016 I was tested for the 4th time to see if I had the thyroid autoimmune disease called Hashimoto’s thyroiditis. It seemed to be the only answer my naturopath could come up with to explain my thyroid tribulations. I dreaded those test results. I thought my life was for sure going to be over if that diagnosis came back positive.

I walked into my follow up appointment and laying on the desk in bold print with my name on the top of the document was the word I’d feared for so many years. Just sitting there, mocking me was the word HASHIMOTO’S. To say that I was angry would be a severe understatement. I felt betrayed by every other health care professional I’d ever seen. Why had it taken this long to find this seemingly simple answer?

I argued with that piece of paper. I argued with the blood results. I argued with my body asking it countless questions about why it hadn’t given me the signs sooner (even though it had). Mid sob session, I looked up at my doctor and said I want to fight this. I’ve heard of ways to rid the antibodies from the body and I’m going to do exactly that. I refused to be defined by that diagnosis. I was going to have children someday. I’d battled my thyroid symptoms for so many years already and in that moment I decided the only way to move forward from this was to take matters into my own hands.

Low-dose Naltrexone for Hashimoto's. A Game Changer.

Have you heard of LDN?

LDN, short for Low-dose Naltrexone, is a wondrous medication that helps treat many autoimmune conditions. It can reduce the thyroid antibodies of Hashimoto’s thyroiditis. Yes. It happened to me.

Naltrexone originally developed in the early 1960s is used in much higher doses to address the symptoms and withdrawals in chronic drug users. It helps block the effects of opioids and reduces drug cravings.

Low-dose Naltrexone & The Immune System

Dr. Bernard Bihari is credited with the discovery of the benefits of Low-dose Naltrexone for normalizing immune system function in his groundbreaking clinical trial of LDN on patients with HIV/AIDS at Downstate Medical Center in 1985-86.[1]

It is termed Low-dose Naltrexone because the amount of naltrexone used is in micro doses compared to the amount given for drug addiction. Studies have now found that Low-dose Naltrexone can be used to effectively treat autoimmune diseases including Inflammatory Bowel Disease, Multiple Sclerosis, Crohn’s Disease, and fibromyalgia.[2-7]

There were very few known risks to taking this prescription, so I found an LDN physician and dove right in.

A local compounding pharmacy created a batch of capsules for me to start my first month’s journey on this medication. The pharmacist provided me with as much education as she could and expressed to me how excited she was for me to try this process. She informed me that I would be experiencing some vivid dreams for the next several weeks, but otherwise that was the only side-effect anyone had reported back to her. She then asked me to keep a journal of my thyroid symptoms and how they were progressing as I went through my treatment. This particular pharmacist had been following the medical journals on Low-dose Naltrexone for many months and was very intrigued to work with someone directly on this matter.

The pharmacist was 100% correct on the vivid and sometimes peculiar dreams. I experienced those for almost 3 weeks, but continued to achieve restful and deep sleep each evening, despite the extreme curiosity for my subconscious’s dream selection. I continued taking the recommended doses for 1 month, then dropped down to the lower dose recommended by my physician. I took the prescription for just shy of 6 months before seeking out another blood test to find out if my levels had shifted.

The results of my next blood test completely blew my mind. In less than 6 months, my thyroid antibodies had become clinically insignificant. For those of you who don’t know what that means…it means they were GONE! That’s right, you read that correctly.

The antibodies that were once attacking my thyroid were no longer significant enough to show up in a blood test. Did that mean I was completely rid of my Hashimotos? Unfortunately, no. Now that my body had developed the antibodies, it was something that could always stir back up later down the line. However, in this moment I was western medicine’s version of Hashimoto’s FREE. The number of emotions that overcame me were so vast I couldn’t hardly stand. I felt liberated, powerful, relieved, and so amazed at how my body was actually healing. I had lost faith in the power of my body so long ago as I battled one illness after the next.

THERE IS MORE…Hashimoto’s & Infections

Now that I had my Hashimoto’s temporarily under control, my next task was to discover the underlying causes of my digestion issues. In July 2017 I went to the Mayo Clinic in Rochester, MN where they found that I had an active staph-infection which had likely been plaguing my body for over 10 years. The infection had caused issues with my thyroid, digestion, adrenal glands, sleep patterns, white blood cell count, and more. Once they isolated the infection and began treatment, I was quickly able to function like a normal (I’ve never been all that normal, it makes life a little more fun) 24 year old.

Digestion Issues? It could be your Pelvic Floor!

Another piece to my Mayo Clinic journey was nothing short of shocking to me was my diagnosis of Pelvic Floor Dyssynergia. This condition doesn’t allow the pelvic floor muscles to relax properly, particularly during a bowel movement. Here is a quote from the International Foundation for Functional Gastrointestinal Disorders.

The pelvic floor is composed of a group of muscles that span the underlying surface of the bony pelvis, which function to allow voluntary urination and defecation. “Paradoxical contraction” refers to an abnormal increase of pelvic floor muscle activity with defecation, rather than the normal decrease in muscle activity that is necessary in order to have a normal bowel movement. This condition can contribute to some forms of constipation, complaints of incomplete evacuation, and straining with stool. Because pelvic floor muscles are controlled voluntarily, their function can be improved through various learning procedures – such as biofeedback.

With a few semi-invasive yet simple tests, the gastroenterologists were able to diagnose this disorder in less than a day. After having a half a dozen other doctors diagnose me with IBS (irritable bowel syndrome) time and time again, this new discovery made so much more sense. While in Rochester, I took part in 2 brief sessions of bio-feedback training, which is essentially Physical Therapy of the pelvic floor monitored with electronic devices. After these sessions, I was able to understand so much more about how my body was processing food and trying to dispose of the waste material, simply by learning which muscles were functioning improperly. Upon returning back to my home in Bozeman, MT, I was participating in pelvic floor physical therapy on an at home basis 3-5 times a day. My digestion and bowel movements drastically improved and are still improving to this day. Where I used to have ZERO relief with my constipation and diarrhea, I now have an understanding of my body and am able to work with it instead of against it.

Even after all this healing, I still experience migraines, but on a much less frequent basis. I manage my compromised immune system and thyroid through a combination of Chinese Medicine and lifestyle care including coaching, counseling, proper diet, acupuncture, massage, exercise, meditation, chiropractic and LOTS of self-care.

    Hi Dana,
    I have had Hashimoto’s for probably decades but a recent test (less than a year ago) only determined that; before then I was being treated for Hypothyroidism. Anyway, like you I was misdiagnosed for many years and in the interim thought I was going down right crazy with mood swings, depression, anxiety…you get it…so now that I know what it is I am actually being proactive in trying to be Hashi free. My Naturopath recently put me on LDN, 4 weeks now, I started on a really low dose .05ml and have now increased it to the .3ml I am to remain on. After reading your post I am very excited to see my results in a few months! I do get a lot of morning headaches though since being on it, other than that my dreams have not changed…

  2. I have Hashimoto’s and hypothyroidism. I am on Thyroid NP 60 mcg medication. My question is, can I take LDN with it. If you know

  3. I am so sick today and I am tired of being sick and tired!!!! IBS, endometriosis, adenomiosis , chronic iritis, pituitary tumors and now hypothyroidism!!!! When does this end? How can I get help?

    • I am seeing a naturopath and she just prescribed this medication to me – if you have not seen one I highly recommend it!

  4. Kaye McClaren says:

    Very curious as to LDN dosing timing. If I’m correct Bihari insited that to most effective it should be taken between 12-4am. What are/is your experiences with timing and thoughts on effectiveness if not taken at that difficult time? Thank you.

  5. How did the doctors test/diagnose your staph infection?

  6. I had the same thing happen with my thyroid antibodies. Unfortunately I had Hashimotos for over 40 years before I found LDN so lots of damage already. Am currently working with Dr to lower my NDT. I have many other autoimmune conditions so will be interested to see how they go with LDN. Thanks for sharing.

    • Hi Denice, All the best with your LDN treatment. I hear from many Hypothyroid Mom readers that rave about LDN for helping their autoimmune diseases. All the best, Hypothyroid Mom.

  7. Kimberly says:

    My dad uses it for his Hashimoto’s and my husband for his MS. It’s been a game changer for both! Currently having my thyroid looked at and will be using LDN if the results come back as suspected. My husband and I recommend looking into LDN to anyone and everyone who has “something” it could help and always get weird looks, but two people in my family are free of big pharma, money making drugs (and their HORRID side effects) and living BETTER lives because of LDN. Finding a doc to treat/prescribe isn’t always easy, but worth it!

  8. Sooo…I actually have LDN. Suspect either fibro or hashis. Can’t get a doctor to test antibodies or run any kind of c reactive protein test etc for pmr. I have had reynauds for decades. I’m 49 and likely perimenopausal and in near constant muscle tension hell. My 4th chiro conceded I have no structural issue but a muscle issue he can’t figure out. Back to my their I have hashi and/or fibro.

    My question…I had genesight done. Naldextrone is tested. Annnndddd for me can up in the yellow zone so the Dr who ran that says she’s never prescribe. Basically says it’s questionable to be effective with my genes. But that is naldextrone as an anti opoid for drug use.

    Worth even trying?? I’m.so confused and stressed and tired of always being in psik and off balance as I’m so tense it throws off my balance.

  9. Happy to hear you’ve found something that works for you. I do not permit posting advertisements for particular products. That’s probably not your intention but I will delete it.

  10. Naomi Pollock says:

    That sounds very exciting, but does anyone know of any doctors in Britain who would prescribe this medication?

    • Hi Naomi, The LDN Research Trust group is holding the LDN 2018 conference in Glasgow Scotland on the 7th July at Glasgow University, Wolfson Medical Building, and will be LiveStreamed around the world online for everyone. I recommend attending livestream as I am, but if that doesn’t work try looking up the various doctors listed under Speakers because several of them are located in the UK. Here is the link to the conference page: http://bit.ly/2sB2Kcm

    • A Chemisr in Glasgiw can arrange for tou to get LDN though you will he required to supply evidence of your disorder. Attached lunk below
