Post COVID Syndrome (PCS) has been part of our language for more than 2 years. Despite that, research on this condition has been progressing slowly. Most of the research in the world has been focused on first figuring out what PCS really looks like and how it affects different populations. While this information is important, many patients are desperate for some news on treatments. Well, today is your day.
In July 2022, a research team from Ireland published their findings on a medication called naltrexone. Naltrexone is a medication that is commonly used to reverse the effects of opioids. For example, naltrexone could be used when someone may have overdosed on a pain medication like morphine. When used for this purpose, the dosage is typically around 50mg. However, when naltrexone is used at very low doses, for example 1-4.5mg, it has shown to work mainly the immune system. With this effect, low dose naltrexone has been used for conditions such as Chron’s disease and chronic fatigue.
In this study, 38 patients with PCS were treated with low dose naltrexone. When symptoms before and after treatment were compared, a statistically significant improvement was found for fatigue, function, pain, concentration, and sleep.
Now, before everyone starts calling their favorite long haul COVID clinic, the study findings need to be interpreted cautiously. As we have discussed before, no research is perfect, and we must go beyond the title to really understand the limitations. First, this study looked at a very small population of patients. The smaller the number of participants, the less reliable the results are. In addition, the results of the group treated with naltrexone was not compared to a group of patients not treated with naltrexone. Without that comparison group, called a control group, we do not know if the reported improvements are due to naltrexone or just due to something completely separate, like the weather or green grass in Ireland. Also, the patients who were treated with naltrexone were aware they were being treated and examined. Just knowing that can sometimes change how someone feels.
Despite all those limitations, I am still excited about this study and others coming down the pike. It represents finally some first steps in treatment research, and it should be a sign of hope for patients with PCS around the world.
At this time, the Mayo Clinic specific post-COVID studies are only recruiting participants that are being seen at Mayo Clinic post-COVID clinics. If you are a patient being seen in Mayo Clinic's post-COVID clinics and would like to participate in research, please email postCovidRSCH@mayo.edu

There are many people in the Neuro V Long-Haulers Facebook group who have new or worsened autoimmune reactions after the Covid vaccines,
myself included. In my case, the autoimmune reaction caused new onset sensory and motor peripheral neuropathy. I am much improved now at 19 months post Pfizer vaccine x 2.
I am not taking any Covid Boosters or any other vaccines until I find out what is happening to my body. I’ve had three biopsies so far & still require two more. Since I had an autoimmune disorder I thought getting the vaccines were going to help protect my health, but I never expected it to destroy it.
Had Covid last week of Oct., 2022. Most days are good, however; some days I get very tired and when I lie down, I’m asleep for at least an hour. When I wake up I feel better, but at times still sluggish.
My PCP says when your tired rest. Good luck to all who still have effects of this much unknown illness.
你好!LDN是什么?能详细说明吗?
My husband is having this issue. It started a week or two after our second Pfizer vaccine. Nothing has helped and they haven’t found any answers with multiple blood tests, neuro visit, rheumatologist visit… it’s been a nightmare & his mental health is affected now too. There is also an odd side effect that occurs closely after eating. Would love any info or connection to anyone experiencing similar. We’ve had covid twice & he doesn’t get too sick with it.
I can sympathize with your husband.
Now I’m developing enlarged lymph nodes.
I just had a lung biopsy on my middle & lower lobe & removal of large node. Frozen section of lymph node came back fibrosis no malignancy.

I developed sensory and motor peripheral neuropathy after the Pfizer vaccine. The nerve damage appears to have been autoimmune-mediated. My ANA titer increased 4-fold when my neurological symptoms were peaking. Many vaccine-injured people have small fiber autonomic neuropathy, which can be difficult to diagnose. Information and support can be found at the Neuro V Long-Haulers Facebook group or React19.org.
I have trouble understanding why people blame the vaccine when they've had covid. Not being very ill with covid doesn't mean you're not going to get long covid in fact your chances of getting long covid or even higher.
I had a very mild case, in fact all I had was a sore throat for the first month. Do not have much of a cough even. I did end up with severe shortness of breath in month four of getting sicker and sicker, all tests negative - only to find out I had a collapsed lung that wasn't being treated because in October of 2020, nobody was taking long covid seriously.
I just found out this week, two and a half years later
With an 02 in the 80s, low 90s, eben 78 the other day, that I'm now needing oxygen 24/7. I had covid before the vaccines came out and I've had vaccines since then. I've also had covid again which caused a spread off my autoimmune pain disorder. I fear deeply that people are blaming the vaccine because they don't know they have had covid because of mild symptoms or just plain denial as I've seen with friends. Or they test negative and never eber tested positive; there's so many false negatives they blame the vaccine and then we end up in the worst trouble.
I'm sorry he doesn't feel well and I hope he starts to improve soon but I'm not so sure about the whole thing about blaming the vaccine. I'm seeing it happen much too often. And then we end up with a lot of anti-vaxxers and now kids are dying of measles again and on and on as suddenly nobody seems to trust ANY vaccine. I hear people say "but measles isn't that bad it doesn't kill people." That's because we have had the vaccine gor a long time that most people trusted until all this anti-covid vaccine started. I'm afraid a lot of disinformation about the covid vaccine is causing people to stop taking vaccines for everything.
People are on such denial about what can happen after covid. People need to stop being in denial about it. I have friends who haven't been able to breathe since covid and they blame asthma instead of covid. Or the vaccine. And end up on more and more asthma medication and more and more testing, don't stay home when they probably do have covid, one even couldnt taste or smell but they test negative so they still went to work.
I'm not saying that the vaccine doesn't affect people at all, what I know from experience is if the vaccine causes you misery then covid could really be bad for you to get, inflammation-wise.
I hope you find an answer that's treatable because long covid is not treatable and people just don't understand. My uncle is doing the same thing. Had a mild case of covid and now he's got parkinsonian symptoms but blaming the vaccine instead of blaming covid. The symptoms started after covid and are well-known symptoms of that can occur with long covid.
I do know that they are finding some of the vaccines are causing trouble, but it's very specific related to the company and the shot but I wonder if they also are blaming the vaccines when it's really a problem with people who have had covid and are saying they never did. They have said don't get the shot close to the time you have covid. People are getting the flu shot and the covid shot at the same time which means neither one of them are effective. According to my cardiologist who treats a minmum of 10 young people a day now with heart disease from covid.
Yep there's a lot we don't know but mostly I think we don't know how much long covid there is and how serious it is. People don't know that people like me exist. My life is basically over because of covid I'm on oxygen 24/7. I'm in pain, on crutches and this is long covid it's not the vaccine. There was no vaccine.
I know this is really going to make anti-vaxxers upset but I think it's worth not blaming everything on the vaccine. I'm just saying... When the vaccine for covid is being blamed for all of long covid issues, then people go in the opposite direction and stop all vaccines. And that's undoing a hundred years of Medical research. Shall we stop all antibiotics?
I just wanted to add that I'm not saying it's not from the vaccine I'm not saying it is from the vaccine I'm just saying don't rule out long covid. More people end up with long covid for a mild case than they do from a moderate case.
Especially if like me you have had it twice, never tested positive in my life, but my IGG blood test shows I definitely had it.
Best of luck. Betty
Since I mentioned we have had covid twice (tested and confirmed), I’m simply saying that the close proximity to the timing of receiving the vaccine is interesting. So it should be considered when trying to figure out how to help him. I don’t understand all the mechanisms, but hopefully some doctor or scientist is able to when they have all the information.
While I appreciate your enthusiasm with propping up vaccines, my post had nothing to do with not getting vaccinated. I am vaxxed and boosted. It’s simply to try and find people who have experienced similar and try and get some relief for him. Thanks.

I tried 1mg Naltrexone in December and had nausea after a couple of weeks - but may try again.
