Fluoroquinolone antibiotics like cipro, levaquin, (and generally anything ending in -ofloxacin), can cause permanent nerve damage and one of the presentations is demyelination of the nerves. [1][2][3]

Permanent nerve damage (neuropathy, pins and needles, tingling, muscle weakness, spasms, muscle twitches, heart palpitations) is a known side effect. There's been no attempt made to study if there's any long term delayed brain effects from fluoroquinolones. "Brain fog" is a commonly reported symptom of those who experience fluoroquinolone side effects. I hope there will be more studies on long term brain health from these drugs, as they're given out liberally.

I can attest. This happened to my wife 15+ years ago. The reaction began after two doses of Levaquin and was 3 months of non-stop living hell. Seriously painful neuropathy, burning all over her body. Profuse sweating all night. Brutal nightmares. Brain fog. Crippling pain in her appendages, melting walls. Extremely distressing.

The doctors were completely dismissive of and uninterested in the symptoms -- it really shook my faith in medical practice. We were on an oddessey to determine what was wrong and could be done to help. It took her 6 months to resume walking more than a short distance. She still has foot and hand problems from permanent neuropathy that affect her daily.

A few years after, Levaquin was black-labelled, and I believe no longer the first line of defense for children at least. The whole thing still burns me.

I suspect this sort of information is no longer rare but if anyone is having this experience then a GABA agonist like benzodiazepine may help you, but be extremely careful as they are quickly dependence forming and must be weened. Small dose.

> The doctors were completely dismissive of and uninterested in the symptoms

I had exactly the same issue! GPs ran a few tests and couldn't figure it out. They labelled is as fibromyalgia, even though I didn't fit the criteria. I pushed to see a neurologist, who ran a few tests and couldn't figure it out - he also labelled it as fibromyalgia, even though when I questioned it he admitted he knew almost nothing about it!

There was a lot of back and forth, with GPs and neurologists being really dismissive. I forget how long this went on for, but a couple of years at least.

So I did my own research over a long period of time. I found only a handful of other cases, but with the symptoms I came to the conclusion that I must have small fibre neuropathy. I pushed the neurologist, who grudgingly did a nerve biopsy, which confirmed small fiber neuropathy. He stopped being dismissive after that.

For pain, I ended up with a similar situation. I tried gabapentin, pregbalin and all the usual things like topical capsicain, TCAs, SNRIs, diazepam, opioids etc. They either didn't help, couldn't be tolerated, or caused more problems. Within the public healthcare systems, the list was eventually exhausted, and they weren't interested in trying anything else. They didn't believe how bad the pain was, and were unwilling in any case to go beyond their list of standard treatments. In the end, I paid to see a private pain specialist, and eventually found ketamine to be really helpful - not just with the pain, but my mental ability to live with it.

I'm unsure of the antibiotics they give post LASIK if they ever do, I'm curious as there is a severe symptom some people get after LASIK called corneal neuralgia that can have similar system wide symptoms to small fiber neuropathy.
Re:Loss of myelin is one of the major factors of age-related... by loceng on Tuesday March 16, 2021 @10:50AM (#26477441)
Was the cause of this an antibiotic? Could there have been any other cause? Did you have any surgeries or injuries around the same time the symptoms started? Did you ever have LASIK eye surgery?
Re:Loss of myelin is one of the major factors of age-related... by randycupertino on Tuesday March 16, 2021 @12:40PM (#26479175)

Thought I replied to this, odd. I don't know what antibiotics they may give after surgery. The reason I asked is some people develop severe corneal neuralgia that has/causes whole body symptoms - central sensitization, hyperalgesia - which sounds somewhat similar to small fibre neuropathy.

I had a similar experience as a child, where a textbook case of a reasonably common disease went undiagnosed for 2 years by doctors before a toll booth worker at an airport diagnosed me. She recognized the symptoms because her dog had it. Sure enough, after my mother brow-beat a doctor into running the absurdly simple blood test she was proven right.

On the one hand, I want to chalk this up to them being like everyone else: 90% of them are just shit at their jobs. On the other hand, I have it on good authority from nearly every nurse I've ever met that doctors are indeed arrogant, dismissive, and often mistaken.

I think there's an extra layer. Any public facing jobs tend to take a toll on you, too. Some more than others. With doctors patients lie to you constantly, for a variety of reasons. Some drug seeking, some simply not wanting to admit it.

Yea, i imagine they're like everyone else (shit), but i also imagine it is very easy become very dismissive in that line of work.

It's a fine line to know what to filter and what to ignore, i imagine.

Re:Loss of myelin is one of the major factors of age-related... by wavepruner on Tuesday March 16, 2021 @09:22PM (#26485422)
I think the issue is more that the healthcare industry makes doctors gatekeepers to healthcare, which can breed tremendous amount of resentment between doctors and patients. A doctor is pressured/forced to provide service to patients, and patients are not legally allowed to seek healthcare from other types of professionals, like biochemists for example, which often have a much better understanding of some diseases than doctors.

When there is so much coercion and lack of consent, people get very frustrated.

>brow-beat a doctor into running the absurdly simple blood test

I feel like I see this story all the time: "a simple test found the issue that they denied I had".

What we should be examining are the incentives for the doctor to resist running tests. Are they too invasive? Some can be, but blood tests certainly aren't. Are they too expensive? Ah, there's the ticket. The doctors are either losing money on tests that find nothing, or they are getting berated by the managers for wasting money on tests that find nothing, or the insurance company is saying no when they ask to run tests.

We have the technology to have proactive medicine. We could be catching cancers in early stages all the time with some standard sets of annual tests. But the economic incentives are all out of whack, and we're waiting until the last minute to do these tests.

Re:Loss of myelin is one of the major factors of age-related... by l33tman on Tuesday March 16, 2021 @11:29AM (#26478090)
Many tests are simply not that good. It's not that simple, like pay $1 for a test that with absolute certainty tells you if you have disease X or not. It would be good if that was the case because then it WOULD have been just a question of money.

But if you have a test that is wrong 20% of the time, and you take this on all your patients every year, you will end up with a huge amount of mental suffering or possibly physical side-effects (unnecessary biopsies, or even surgery). You might end up giving people long runs of unnecessary meds. OTOH, you might end up missing some diagnoses if you don't do some tests. Balancing all of this is difficult.

Of course this is not news to the medical profession, this is a big input to the standard flowcharts. And you can always find anecdotal edge-cases that think their particular case was crystal clear and should have immediately been diagnosed. But don't assume that medical diagnosis and treatment is as trivial as doing a blood test and some googling.

I will note that in my case the test is routine and reliable and has been since before I was born.

Re:Loss of myelin is one of the major factors of age-related... by goda90 on Tuesday March 16, 2021 @02:16PM (#26480696)
Sure you can't take every test at face value. How you approach the results of something that isn't 100% accurate is important. A potential false positive should mean a follow-up test, not a full diagnosis. Or even just holding onto the information until it can be part of a bigger picture with presenting symptoms. You don't even need to tell the patient what the results MIGHT point to, so you don't encourage hypochondria.

I often wonder why such an expensive device as an MRI machine isn't utilized 24/7. I'd gladly go in for a scan at 3am if it meant paying even as little as 20% less.

Re:Loss of myelin is one of the major factors of age-related... by wavepruner on Tuesday March 16, 2021 @09:19PM (#26485404)
The really strange thing about tests is even if you pay out of pocket you still have to get a doctor to sign off on it, which dramatically increases the friction and price for testing.

It's just information about your body. You shouldn't need a doctor's approval for that.

Doctors operate in an environment of extreme uncertainty, because human biology is so complex and so poorly understood.

At the same time, doctors are rewarded for acting as though they are certain.

Not unlike internet commenters rewarded with karma for condemning doctors across the board with certainty.

Humans crave certainty in an uncertain world.

The consequences of being wrong in the comments section is significantly less, imho. Plus, doctors are paid a lot for their expertise. It's really not about craving certainty. It's a question of a system that disincentivizes thinking through a problem that doesn't slot well into the diagnostic framework taught in medical schools to students selected for their ability to think inside the box, with little requirement, or really, possibility, to be very deep in biochemistry, pharmacology, research science, or a host of other inputs. Oh, and they're often very arrogant.

Doctors do save many lives but I fully agree a whole lot of them are indeed terrible at edge cases and what's worse is the arrogance they display when one tries to explain the symptoms clearly. Some of them go as far as recommending a psychiatrist when it is really not called for (sure, there are instances of hypochondriacs but how about the rest who aren't? ).

in my own experience (with my wife's chronic condition), most doctors are extremely dismissive if they don't have the answer off-hand. I don't know why this is - but reactions ranged from saying she was lying or was addicted to painkillers (despite not asking for painkillers) to switching back and forth between two common diagnoses even though they were quite clearly inaccurate. I have no faith in the front-line medical system to be able to deal with anything less blatant than a broken bone or a flu, if only due to what appears to be doctors' near-universal refusal to respond to uncertainty with humility and curiosity.

After many similar experiences with doctors, I have reluctantly come to the conclusion that about 80% are only interested in time preservation and ego preservation.

If they don't know the answer in 5 minutes, then obviously you must be crazy. 2 minutes, if you're a woman.

They are allergic to 3 little words: "I don't know."

I'm sorry to hear about what happened to your significant other.

I developed permanent neuropathy and muscle problems in my lower legs after a course of Levaquin for a respiratory infection. Constant fasciculations, cramping, and pain.

It sounds like you've done your research on potential treatments, however in case you're unaware, I've found considerable relief by soaking my lower legs daily in an Epsom salt bath. I can attest to the fact that magnesium sulfate is without question topically permeable. It may be something for your wife to consider, to see if it helps her.

Frankly, at this point it's pretty clear that the entire healthcare system in the US is parasitical: doctors, hospitals, insurance companies and pharma companies. Their purpose is to extract value, not restore health.

I have a very low opinion of doctors, who are by and large arrogant and of middling intelligence, a dangerous combination when a person's health is at stake.

I was prescribed Cipro for a urinary tract infection and the doctor didn't once mention anything about dangers or side effects for the drug, just said he's 'prescribing an antibiotic'.

After the very first pill I was feeling pins and needles in my extremities later that day. I stuck with it for a few more days, each pill feeling even more pins and needles, more intensely and in more places on my body. Once I started feeling it in my face, I called the doctor and they got me on a different antibiotic.

Then I started reading horror stories about the drug and it made sense. I also didn't exercise for a year afterwards out of fear that my achilles tendon would snap, one of the biggest warnings that was on the box and one of the things many of the online horror stories said happened to them.

The neuropathy (pins and needles) lasted for six months before it started going away, and it comes and goes periodically, years later (it's mostly gone now, thankfully). I've had other health issues since that are known possible health issues from Cipro (it's so invasive and effects so many systems of your body). One of the more annoying ones lately is the onset of Tinnitus, which Cipro is known to cause. Maybe it's just a coincidence, but I'll never know for sure since most doctors still don't treat Cipro toxicity seriously or know how to test for it.

I don't think it caused brain fog, but who's to say? I don't feel as mentally acute since then, but I'm also older.

Not really looking forward to any future health problems it may lead to, and I only ever took like 5 pills of the damn thing (it was over 7 years ago now).

I'm so pissed off I wasn't even warned about this, and that it was so casually prescribed without warning. I've taken other antibiotics before and only had to worry about my gut biome getting screwed up, so I wasn't expecting to have such a terrible reaction to the meds.

Re:Loss of myelin is one of the major factors of age-related... by throwaway584568 on Tuesday March 16, 2021 @07:37AM (#26475412)
I have a similar story, with an antibiotic that is also an immunosuppressant (I was taking it for that effect). After taking it for just 2 weeks, I had terrible pain in my arms and legs. My doctor suggested I keep taking it for a couple of weeks more, to see if it went away. It got worse, and I stopped it a week or so later. I understand this is a very rare side effect, so rare I don't think it was even mentioned in the leaflet - I'm just incredibly unlucky to have such a reaction.

I was left with small fiber neuropathy (nerve damage) in my arms and legs, and with CFS (Chronic Fatigue Syndrome) too. This means I'm in constant, unending pain (which takes a huge mental toll), that I'm tired all the time, and if I do any more than the gentlest of exercise, I fall asleep and am more tired and in even more pain for days or even weeks afterwards. It's fucking horrible.

This was about 6 years ago, and I'm pretty sure it's permanent. I haven't quite given up hope though - I have several Google Scholar alerts setup, and read several papers every week, in the hope of finding something that might reverse things even a bit.

I don't want to mention it's common name specifically, as this is rare enough that it could be linked to me personally.

It is actually an antibiotic (I'd somehow forgotten that - edited my original comment now!), but once that acts as a immunosuppressant, and it's less-common name is diaminodiphenyl sulfone.

I had very horrible side effects from Levaquin for an asymptomatic infection I was diagnosed with. They gave me 12 hour doses, which I took twice .. I had fever, nausea, severe joint pain, and a lot more.

Later, both in the US and the UK, future doctors, when describing this to them, said I was misinformed, that probably I was sick, these are not side effects.

No, they're misinformed, and I'm deeply suspicious of the medical profession.

I was prescribed cipro after a rectal surgery (chronic anal fissure and hemorrhoids) in Feb 2020. By that time, I wasn't aware that cipro was actually a poison. Fortunately, I haven't experienced any such side effects so far, except occasional palpitations (likely due to loneliness, my increased anxiety because of the pandemic and staying indoors all the time).

Everything is a poison to some extent.

Antibiotics are poison to bacteria.

The difference here is that you're not a bacteria and can safely metabolize the drug itself.

Chocolate is poison to dogs. Not to humans.

One course of an antibiotic isn't going to rot your brain or nerves... and even then, chronic use isn't a problem but for a small percentage of people who do experience these adverse reactions.

All eurkaryotic cells have little trapped bacteria inside themm -- your mitochondria. The mutualistic cooperation between the mitochondria and the surrounding cell is an ancient and delecate dance.

Look, I don't know anything about this medication. But the grandparent responded to a pure anecdote, including the claim that it is "a poison". It seems an entirely appropriate response to caution against false taxonicity in this context. I don't see why the thread is so full of downvoting and accusations.

If someone wants to claim an approved medication is especially poisonous, the onus should be on them to provide evidence. Note that the great-great-grandparents 3 links are all individual case studies. One of them summarizes the situation: "overall, the frequency and severity of adverse events are rather low".

Re:Loss of myelin is one of the major factors of age-related... by thatcat on Tuesday March 16, 2021 @12:38PM (#26479142)
That's fair enough. I would personally not risk nerve damage even if "frequency and severity are rather low" (1.5% reported in pubmed) unless necessary because the mechanism of action is still there and I don't have any information about why that happens sometimes. It would be great if our medication review could extend past trials and allow people to independently analyze the data in population studies so some causation could be investigated in those rare events when things go wrong.
Re:Loss of myelin is one of the major factors of age-related... by techrat on Wednesday March 17, 2021 @12:54AM (#26486713)
Bear in mind, with a lot of different types of medications, they're required to report severe reactions found during trials and use... even if those reactions were very specific to that individual (genetic predisposition, for example)... Eg, Stevens Johnson Syndrome (a really severe skin reaction) which has no real general consistency on who reacts to what class or type of drugs.

If one person experiences it in a trial of a group of, say, 60... That becomes a risk of 1.6% in the side effects profile.

Real world cases would be much, much, much lower to the point to where doctors in the ER wouldn't even know what they're looking at when it happens. Sometimes it gets diagnosed as a 'drug eruption' or an allergy, when it's more an immune hypersensitivity response.

I know anecdotal isn't what people want around here, but I had a reaction to Sulfa that was later diagnosed as Stevens Johnson Syndrome. The doctor who prescribed it to me never personally saw a case of it herself until I came along. Even then, she sent me to a dermatologist first.

https://www.webmd.com/drugs/2/drug-5530/bactrim-ds-oral/deta...

However, It's commonly listed at the top of the side effects list for this drug.

https://en.wikipedia.org/wiki/Stevens%E2%80%93Johnson_syndro...

Actual incidence of the syndrome?

> SJS is a rare condition, with a reported incidence of around 2.6[10] to 6.1[26] cases per million people per year. In the United States, about 300 new diagnoses are made each year. The condition is more common in adults than in children.

Up to 6 cases per million per year across ALL drugs and not just the one I mentioned here.

Even common over the counter medications like Ibuprofen is known to cause SJS. The odds, however, are vanishingly small.

The risk exists, yes, but the perspective needed is that when you see percentages reported... that's not a "1.5% chance", that is "1.5% of those in a particular group experienced this side effect while 98.5% did not."

This information is typically provided in the published drug facts for each medication.

It's through trials they discover the incidence of side effects and appropriate dosages for maximum therapeutic benefit.

Nobody is waving anything off when providing perspective.

One course of an antibiotic might not "rot your brain", but one course of a corticosteroid certainly can.

https://en.wikipedia.org/wiki/Steroid_dementia_syndrome#Case...

I was on prednisolone for a couple of months a few years ago. I can't say I was very intelligent before that, but it's certainly took a toll on my memory and cognitive abilities. (No, it's probably not hypochondria, I didn't even know corticosteroids could have such consequences when I noticed the problem.)

> The treatment with steroids was stopped and three years later (while still taking buspirone, albuterol, fluticasone and salmeterol inhalers, loratadine and theophylline)

Yeah, this was more than just one steroid doing something to him. When you have a situation where someone is on that many different medications, it's no longer a case where you can simply point to one thing and say "that caused it." There's no telling what other underlying conditions were exacerbated in the process and what side effects may be due to the drugs NOT discontinued.

Long term use of steroids is known to cause all kinds of nasty side effects. Prednisone I've actually found rather useful for bootstrapping myself out of depression but it tends to induce mania. Going for longer than a few days results in a huge high followed by a massive crash.

The above sounds like nuclear option amounts of asthma meds and it's reasonable to expect potential long term effects.

That being said, inhaled steroids are considered much, much safer than oral ones, due to much smaller doses and targeted effects.

Those are two cases of one person each, with different specific symptoms. It's important to note that both of the people mentioned developed such negative effects quickly or immediately, which means that the other 99.99% of people do not react the same. Also, the first person got a bunch of active ingredients, of which steroids is just one. So I would temper my warning.

Have you thoroughly researched fluoroquinolones? Millions of people like myself have experienced tendon or nerve damage from one course. And besides the known cases, it often goes unreported because people don't realize their sore ankle might have anything to do with the pill they've been prescribed for a cough.

On the day of the 9th dose of 10, I found that I was limping on my right foot. I've never had tendon issues but it was clearly the tendon that was weakened and sore. I also found my hand grip was weak and it was painful to even wring out a wet face cloth. Luckily my Achilles tendon didn't rupture as sometimes happens with this complication. But limping everywhere isn't fun, and even just climbing or descending a staircase became a difficult chore.

The issues lasted about 6 months, during which time I took a few daily supplements recommended in the research I found. I seem to have fully recovered but I've read about others not so fortunate.

Actually most of us are bacteria on a cell count basis. This is an observation worth taking into account when taking antibiotics. However that does not mean we shouldn't take them.

Confident asides as in '(we) can safely metabolize the drug itself' are unhelpful and indeed wrong for certain people.

I recently got ear drops for a somewhat mild issue I had. The issue didn't go away, but after your comment I remember occasional "pins and needles" in my leg - just looked it up and those drops contain Ciprofloxacin!

Though it seems a bit unusual that drops in one of my ears would first cause symptoms in a leg. OTOH, that would be a curious coincidence... Luckily the pins and needles were only mild and transient, so if there was a causation I hope it was only temporary.

Translated: Compared to a chemotherapy drug designed to cause DNA breaks to prevent cell replication, ciprofloxacin produced similar "sister chromatid exchange" counts, which happen when damaged DNA strands need to pull in duplicate material from "sister" strands.

Counting SCEs is also used to measure human DNA mutations from things like carcinogens and radiation.

Re:Loss of myelin is one of the major factors of age-related... by stevebmark on Tuesday March 16, 2021 @02:28AM (#26473638)
The side effects aren't well known / understood. They also happen to less than 1% of people who take the drugs (at least that's the current estimate, some side effects may not be properly linked to the drugs). There's very little research on how to measure the damage done by fluoroquinolones. Once a patient says they have tingling, the drugs have already caused permanent damage, and a doctor isn't going to know what to measure to assess this damage, nor what they should have been measuring to prevent the side effect in the first place. This lack of understanding may lead to an inflated sense of safety profile.

They're used to treat antibiotic resistant infections in "hard to reach" places, since the fluorine moiety allows them to penetrate most places in the body (which is also likely related to how they cause insidious damage). This power+reach makes them a default drug for some doctors to treat infections.

Re:Loss of myelin is one of the major factors of age-related... by ohazi on Tuesday March 16, 2021 @02:19AM (#26473592)
We shouldn't. You probably don't want to take a quinolone antibiotic unless all other options have failed and your life is at risk. There are decades of reports of permanent, severe nerve damage after as little as a single dose. At one point the FDA even had to step in to force some unusually severe language in warning labels.

But doctors can be a stubborn bunch, and many still prescribe it way too liberally.

Knowing doctors, this comes down more to Hanlon's razor.

Many don't know any better and have a poor grasp of the scientific method. For many being a doctor is more of a trade than a profession.

Their scope of work is too broad and they're far too busy to keep up. As a result, they're perhaps even more susceptible to marketing than average people. They don't have time to dig into pubmed and deeply understand something they see (generously) 1% of the time.

They have to rely on people who otherwise get paid to do the research. If there's no money to be made from a treatment, it won't be able to donate to universities, fund studies, or pay for advertising.

Doctors won't hear about it.

It was the first thing prescribed to me, but I was only told "it's an antibiotic" and I had no bad issues with other antibiotics so didn't expect that I needed to be careful.

I probably took at least four more pills than I should have, even though I had a bad reaction after the first pill, I assumed it was something else that was causing it at first.

Glad I eventually made the connection, read some horror stories to confirm the likely cause, and called the doctor to switch my antibiotic before I had taken all 30 pills. Might be a lot worse off now if I had.

Re:Loss of myelin is one of the major factors of age-related... by matheusmoreira on Tuesday March 16, 2021 @07:28AM (#26475349)
Because the benefits of antibiotics vastly outweigh the risks. You're better off taking antibiotics than getting a serious infection.

They should be used rationally though. Ciprofloxacin and other antibiotics in the same class are stronger medications compared to penicilins for example. The ideal situation is to figure out what the bacteria is sensitive to with a culture and antibiogram and then choose the weakest, most specific antibiotic out of that list. Of course, this requires time and resources which may not be available. In some cases, it's been proven that waiting for test results leads to worse patient outcomes so doctors will prescribe antibiotics empirically and adjust treatment later.

But isn't antibiotics something that gets given out in many countries for more or less anything? The US comes to mind. Which to my knowledge is the reason why more and more people in those countries dies of resistent bacterias.

I'm 35 and have been given antibiotics twice in my life, and reading about people getting antibiotics for a cold baffles me.

> But isn't antibiotics something that gets given out in many countries for more or less anything? The US comes to mind.

Yes. Antibiotics have a rich history that dates all the way back to the second world war. Before the risk of bacterial resistance became well-known, use of antibiotics was much more widespread. Understanding of bacterial resistance came after they developed mechanisms to resist the drugs used to treat infections such as betalactamase.

It could be the case that cipro- and levofloxacin are widely prescribed in the USA because bacteria have already become resistant to weaker drugs. Treatment guidelines in my country have more effective options compared to CDC sources. I have no first-hand experience though.

Stronger antibiotics also happen to be very easy to use. It's generally much easier to successfully treat someone with a strong antibiotic than a weaker one. One pill once a day for three days is much easier than 3 or 4 pills at regular intervals every day for 10 days. Getting people to take pills correctly is an every day challenge in medicine, complicated treatments means people will often forget to take their pills and reduce their effectiveness.

If you tell a doctor that you had a bad reaction in the past, he or she will check a data sheet and assume you're insane or exaggerating.

There's some corruption going on in the data, perhaps? There are so many anecdotes from this class of drug, they cease to become 'just anecdotal.'

False. They're absolutely given as a drug of first resort, all the time, in many places of the world. Happened to me.

Another reason is that an entire course of Cipro is like five days.

There is often no "perfect" ligand because benefits somewhere cause harm somewhere else since evolution reused so many substrates, or the means of regulation similarly ups or down regulates anti-target activities.

Furthermore, compounds that will work are often constrained by many factors.

Well that puts you in a high risk group. Any temporarily high increase in IOP can trigger a tear easily, e.g. an accidental poke. Giving birth is risky with such high myopias. Aging of course... once in 50s I'd do annual checkups on the posterior of the eye if I was a high myope. And drugs for sure didn't affect the shape of your eyeball.

I'm not saying antibiotics don't do any damage, I'm just saying that in such a case those would be at the back of the blame list...
