Fluoroquinolone Antibiotics Associated with Carpal Tunnel Syndrome

It is well-known and well-documented that fluoroquinolones weaken and destroy musculoskeletal tissues–especially, but not limited to, tendons. 

Additionally, it is known that fluoroquinolones cause neurological problems, and can lead to painful and debilitating peripheral neuropathy. (In 2013, fluoroquinolone warning labels were updated to note that Cipro/ciprofloxacin, Levaquin/levofloxacin, Avelox/moxifloxacin, and Floxin/ofloxacin can cause permanent and disabling peripheral neuropathy.)

Given that fluoroquinolones disproportionately affect the tissues in joints, and that they also adversely affect nerves (causing painful neuropathy), it’s not surprising that fluoroquinolone antibiotic use is associated with Carpal Tunnel Syndrome (CTS)–a medical condition that includes “pain, numbness, and tingling, in the thumb, index finger, middle finger, and the thumb side of the ring fingers,” as well as weakness and muscle wasting.

Both CTS and fluoroquinolone-use are common in America, and researchers Jasmine Z. Cheng, Mohit Sodhi, Mahyar Etminan, and Bruce C. Carleton, examined how they are related in “Fluoroquinolone Use and Risk of Carpal Tunnel Syndrome: A Pharmacoepidemiologic Study” published in the journal Clinical Infectious Diseases in August, 2017.

In “Fluoroquinolone Use and Risk of Carpal Tunnel Syndrome: A Pharmacoepidemiologic Study” the researchers found that, “Any use of FQ within the year prior to CTS diagnosis was associated with a 34% and 36% increased risk of CTS in the primary and sensitivity analyses, respectively” and that:

“The results of our study are consistent with an increase in the risk of CTS with FQs. The risk was consistent among all risk periods with a slight increase among past users, which may be due to the longer period elapsed for CTS to manifest itself. FQ-related neurotoxicity can persist cumulatively in relation to exposure levels [8, 9]. The exact mechanism by which this occurs is unknown [9], but proposed models include direct nerve inflammation and ischemia from toxic metabolite and free radical formation [10], and FQ-induced tendonitis/tendinopathy causing mechanical compression upon the adjacent nerves (eg, median nerve) that share the carpal tunnel [11]. Reports of nerve biopsy studies on patients who have experienced FQ adverse events have revealed significantly reduced nerve fiber density consistent with small fiber neuropathy, which may be a potential mechanism of CTS [12]. Although neurotoxicity is the second most commonly reported adverse event, with several studies documenting FQ association with central and peripheral nerve damage [8, 9], this is the first large-scale study exploring the relationship between FQs and CTS.”

CTS is a malady that affects thousands of people and has societal costs in the millions of dollars. In “Fluoroquinolone Use and Risk of Carpal Tunnel Syndrome: A Pharmacoepidemiologic Study” the researchers note that:

“CTS is a disease of significant societal burden with a prevalence of 5% and incidence of up to 2.3 per 1000 person-years [4, 5]. CTS causes loss of function and decreased quality of life for individual patients, and also comprises a large cumulative drain on healthcare and socioeconomic resources from loss of productivity and worker’s compensation claims [6]. One study of 4443 CTS claimants in Washington State estimated a cumulative socioeconomic cost of US$197–$382 million over 6 years for this cohort alone [6].”

Fluoroquinolones are increasing the risk of CTS in millions of people (20+ million prescriptions for fluoroquinolones are written each year). Are doctors or patients aware that they are increasing the patient’s chances of CTS–a painful, debilitating, and costly condition–when fluoroquinolone antibiotics are taken? I doubt it, but they should be.

Please spread the word about how dangerous fluoroquinolones are by sharing posts, news articles, and research articles that connect fluoroquinolones with other illnesses. It wouldn’t occur to most people that a commonly prescribed class of antibiotics could be connected with CTS, psychiatric illness, pain, pseudotumor cerebri, tendon damage and ruptures, or multi-symptom chronic illnesses. But fluoroquinolones ARE connected with those, and other, diseases and syndromes. Articles like “Fluoroquinolone Use and Risk of Carpal Tunnel Syndrome: A Pharmacoepidemiologic Study” help to provide evidence of the extensive damage that fluoroquinolones do, and I am grateful to the researchers who examined the connections. Please spread the word so that doctors and patients alike are informed. Thank you.

 

 

Fluoroquinolone Warning Labels to be Updated in Canada

Health Canada, the department of the government of Canada with responsibility for national public health (like the U.S. Food and Drug Administration) has “carried out a review of the potential risk of persistent and disabling side effects linked to the use of fluoroquinolones. The review was triggered by a benefit and safety review done by the United States Food and Drug Administration (FDA) on systemic (taken by mouth or by injection) fluoroquinolone drugs.”

The Canadian Review of fluoroquinolones concluded that (SOURCE):

  • Health Canada’s review concluded that some of the known side effects, specifically tendonitis/tendinopathy, peripheral neuropathy and central nervous system disorders, already linked to the use of fluoroquinolones, may be persistent and/or disabling. Given the high use of fluoroquinolones in Canada and the information reviewed, these side effects are considered rare.
  • Health Canada recommended that the safety information for all fluoroquinolone products be updated to include information about this rare but serious risk. Health Canada is working with manufacturers to update the safety information of all systemic (taken by mouth or by injection) fluoroquinolone products marketed in Canada. In addition, an Information Update and a Health Care Professional Letter will be published and distributed to further inform Canadians and healthcare professionals about this risk.
  • Health Canada is working with the Drug Safety and Effectiveness Network (DSEN) and the Canadian Agency for Drugs and Technologies in Health (CADTH) to conduct additional studies to better understand the use of fluoroquinolones in Canada.
  • On October 6, 2016, Health Canada brought together a Scientific Advisory Panel on Anti-Infective Therapies to discuss the risks associated with the use of fluoroquinolones. The panel recommended that the safety information for fluoroquinolones be updated, and risk communications be published and distributed to further inform Canadians and healthcare professionals about the potential risk that some of the known side effects, specifically tendonitis/tendinopathy, peripheral neuropathy and central nervous system disorders may be persistent and/or disabling.
  • Health Canada will continue to monitor safety information involving fluoroquinolones, as it does for all health products on the Canadian market, to identify and assess potential harms. Health Canada will take appropriate and timely action if and when any new health risks are identified.

As a result of its safety review, Health Canada is working on updating fluoroquinolone warning labels.

Additionally, above and beyond what the U.S. F.D.A. has done, Health Canada has agreed to publish and distribute a Healthcare Professional Letter regarding fluoroquinolone risks. The Healthcare Professional Letter includes the following points:

  • It is recommended that the potential for disabling and persistent serious adverse events be considered when choosing to prescribe a fluoroquinolone.
  • Fluoroquinolones should not be prescribed to patients who have experienced serious adverse reactions during or after prior treatments.
  • Healthcare professionals are advised to stop systemic fluoroquinolone treatment if a patient reports a serious adverse reaction. The patient’s treatment should be switched to an alternative treatment with a non-fluoroquinolone antibacterial drug if needed to complete the treatment course.
  • Healthcare professionals should be aware that some adverse reactions associated with the use of fluoroquinolones can occur within hours to weeks after exposure to the treatment.

This acknowledgement from Health Canada that fluoroquinolones may have permanent and/or disabling effects is a huge step in the right direction for Canadian “floxies.”

All Canadians who have experienced adverse reactions to fluoroquinolones are encouraged to report their reactions to Health Canada through the Canada Vigilance Adverse Reaction Online Database.

This acknowledgement from Health Canada is a huge step in the direction of safety and informed consent for all Canadians. It is appreciated!

Vision Problems from Fluoroquinolones

A few years ago, I was chatting with a work associate about fluoroquinolone toxicity, and she mentioned that a friend of hers had lost her vision after taking ciprofloxacin. Yes, you read that correctly–her friend LOST HER VISION as a result of getting floxed. I was shocked and appalled. Losing my energy was bad enough, I can’t even fathom going blind, even temporarily, from taking an antibiotic. My associate’s friend had to take more than a month off of work, and several months off from driving, in order for her eyes to heal and her vision to return to a level at which she could return to doing those things. Her vision did return, and I believe that this was her only side-effect, but still, losing one’s vision is a pretty serious and severe side-effect. I’d be pretty upset if I COULDN’T SEE as a result of taking an antibiotic.

I have heard from many other people who have suffered from vision problems, including blurred vision, floaters, dry eyes, “visual snow,” and a loss of comprehension of visual information, post-flox.

In a comment on this site, Joyce described her vision problems as follows:

“Could Levaquin caused my visionroblem that happened sudden? Yes, I can type but onlyk because I’ve done years and years of 12-18 hour days of typing so as long as I know where the keyboard is, I can type — can barely see the letters so errors elude me.

Sunday, October 9, 2016, myvision went from being okay to not there in the blink of an eye — literally. My husband and I were eating lunch in a restaurant, someone sat down at a table near us, I glanced over, when I glanced back at my husband, my vision was gone except for a narrow bright white area to the right and bottom of my vision field. Called optometrist, he initially diagnosed a pin stroke and told me to go to ER, so I did. CT at ER showed nothing but as precaution, was given TPA and flown to major hospital. Three CT scans there showed nothing. Ultrasound of heart showed it to be in good shape. Cholsterol loa, blood sugar low, BP kept dropping on its own so docs happy with all that. MRI showed “shadow” in right temporal lobe — docs didn’t know if it was bleeding or what, nor how long it had been ther enor if it would go away.

Upper left quadrant of visual field seems as if I’m looking through a dense brown fog. Rest of visual field is useable — can get around on my own, do housework, walk, etc., but can’t see to drive, read nor do my job which is thypesetting and graphic design. Dark area has decreased by about 70% since initial onset but isn’t improving past that.”

In “Painful Dry Eyes” on www.fluoroquinolonethyroid.com, JMR describes her post-flox dry eyes as follows:

“The severely dry eyes affected everything: my ability to read, to watch TV, to use the computer, to write, to look out on the world; to be athletic, to be outside in the wind or cold night air; to blink the 23,000 -30,000 times a day the average person blinks without feeling the dry, gritty pain with each one of those blinks; to sleep at night without waking up constantly in pain just from my dry eyes alone. There’s “dry eyes”, and then there’s “Bone-Dry eyes” – zero moisture what so ever – and I simply couldn’t live a life worth living with that.”

The warning label for Cipro/ciprofloxacin notes that, “blurred vision, disturbed vision (change in color perception, overbrightness of lights), decreased visual acuity, diplopia, eye pain, tinnitus, hearing loss, bad taste, chromatopsia” are special sense related adverse-effects that have been reported. The warning label text feels so flippant–as if decreased visual acuity and/or eye pain aren’t serious, life-altering, horrible side-effects for a drug to have. Did anyone’s doctor warn them that they may have long-term vision problems as a result of taking Cipro/ciprofloxacin, Levaquin/levofloxacin, Avelox/moxifloxacin, or Floxin/ofloxacin? No? I didn’t think so.

If you read the full “Painful Dry Eyes” post on www.fluoroquinolonethyroid.com you will note the connections that the author makes between thyroid hormone (and iodine) levels and the severity of her eye-related fluoroquinolone toxicity symptoms. If you read through more posts on www.fluoroquinolonethyroid.com you will see that there are many connections between fluoroquinolone toxicity symptoms and thyroid hormones. A summary of the connection can be seen in the post “Fluoroquinolone Antibiotics and Thyroid Problems: Is there a Connection?” on www.hormonesmatter.com.

It is clear from patient reports that fluoroquinolones badly affect hormonal stability and balance. The site, www.fluoroquinolonethyroid.com, goes over how thyroid hormones are adversely-affected by fluoroquinolones. Patient stories such as Andrew’s Story and Gary’s Story go over how fluoroquinolones deplete testosterone. Many women have reported that their fluoroquinolone toxicity symptoms are greatly affected by hormonal fluctuations that correspond with their menstrual cycles. Additionally, in the article “Musculoskeletal Complications of Fluoroquinolones: Guidelines and Precautions for Usage in the Athletic Population” several endocrine-system disorders are listed as risk factors for fluoroquinolone-related musculoskeletal problems.

Hormones also greatly affect vision and eye health. In “Blinded By Side Effects: Vision and Hormonal Birth Control,” Kerry Gretchen states:

“Hormones affect every system of the body so perhaps it should come as no surprise that they can greatly impact your vision. In fact, it is the fluctuation in hormones that is the primary reason for worsening eyesight with age. So of course, manipulating the body’s natural chemistry by using hormonal birth control can cause a variety of vision problems.”

Blinded By Side Effects: Vision and Hormonal Birth Control is an interesting and insightful post that I recommend you read for more information about the hormone-vision connections. Though it focuses on how hormonal birth control affects vision–not on connections between fluoroquinolones, hormones, and vision problems–the connections just between hormonal disturbances and vision problems are interesting and relevant to “floxies” of both sexes.

I believe that post-flox vision problems are related to hormone imbalances. Working with a good doctor to help get your hormones back in balance (or, at least to run some tests) seems like an appropriate course of action for any “floxies” who are suffering from severe, life-altering, vision/eye related side-effects. Hormones are notoriously difficult to balance though, and caution is warranted. “Balancing your hormones” may be easier said than done, but working on it, and getting information from a doctor who works with patients with hormonal problems, seems like a good path to start down.

Time may also help. My peripheral vision floaters went away less than a year after getting floxed, and my eye moisture returned a few years after that. (My eyes were never dry to the point that they were painful, but I didn’t wear contact lenses for a while post-flox. I can wear them again.) I can’t pinpoint anything specific that helped other than time and maybe acupuncture. My vision problems weren’t near as bad as those of my work associate’s friend, Joyce, or JMR though. If my symptoms had been that severe, I probably would have been willing to try pharmaceutical and/or supplemental hormonal adjustments.

As is the case with most fluoroquinolone toxicity symptoms, there is no cure for vision-related fluoroquinolone toxicity issues, and even getting recognition of the reality of the multifaceted adverse-effects of these drugs is difficult.

Fluoroquinolone toxicity symptoms are severe, fluoroquinolones adversely affect multiple bodily systems including vision, and the symptoms of fluoroquinolone toxicity are often not reversible through medical interventions. Therefore, fluoroquinolones should not be prescribed unless absolutely medically necessary. This isn’t that difficult a concept–it should be reality.

Serious Psychiatric Reactions from Fluoroquinolones

Heather McCarthy News Story

Please read and share post, “Psychiatric Adverse Reactions to Pharmaceuticals Ignored” that was published on Hormones Matter. It highlights the tragic story of Shea McCarthy, a young man who lost his life after suffering from a severe psychiatric adverse reaction to Levaquin.

The severe psychiatric adverse reactions to fluoroquinolones need to be recognized and acknowledged. No one is choosing to have a severe psychiatric adverse reaction to a drug, yet people with psychiatric adverse reactions are often ignored and disregarded. As you can see from Shea’s tragic story, not listening to people who have psychiatric adverse reactions to drugs can have tragic consequences.

Here is the video of the news story, “CALL 6: Mother blames antibiotic for son’s death – Purdue University student took Levaquin:”

There are several possible mechanisms through which fluoroquinolones can cause anxiety, depression, insomnia, psychosis, and other severe psychiatric adverse-effects. Oxidative stress may be the mechanism through which fluoroquinolones cause severe psychiatric problems, as I described in “Can Antibiotics Induce Psychiatric Reactions?” Maybe gut microbiome destruction by fluoroquinolones leads to the psychiatric adverse effects. The Psychology Today article, “The Gut-Brain Connection, Mental Illness, and Disease” goes over evidence that our gut microbiome is intricately linked to our mental health. Obviously, fluoroquinolones are powerful antibiotics that destroy the gut microbiome. Another possibility, one that I have not previously explored, is that fluoroquinolones cause severe psychiatric reactions because they have a piperazine attachment to the quinolone core. In the picture below, the quinolone core is zone 4 and the piperazine attachment is zone 3.

Cipro Molecular Structure

Ciprofloxacin is 1-cyclopropyl-6-fluoro-1,4-dihydro-4-oxo-7-(1-piperazinyl)-3-quinolinecarboxylic acid.

Piperazine blocks GABA activity. GABA is gamma-Aminobutyric acid, “the chief inhibitory neurotransmitter in the mammalian central nervous system. It plays the principal role in reducing neuronal excitability throughout the nervous system. In humans, GABA is also directly responsible for the regulation of muscle tone.” (wiki) When GABA is blocked, people feel edgy, agitated, excited (not in a good way), anxious, and can suffer from insomnia, muscle spasms, seizures, and more.

Piperazine is often used “for making fake ecstasy because of the similarity in taste, and at certain doses, a user may experience favorable side effects and feel ‘high.’” (source) It is also often mixed with MDMA in ecstasy.

Additionally, it is noted in “Acetylcholine (ACh) – Related Damage” on http://fluoroquinolonethyroid.com/ that:

“Piperazines (anti-parasiticals which kill parasites by paralyzing them) have neuromuscular effects which are thought to be caused by blocking acetylcholine at the myoneural junction. (Plenty of pets have been poisoned with over the counter piperazine toxicity from wormers – so no, it’s not just helminths they affect). Among the numerous properties of Piperazine derivatives, they are not only muscarinic antagonists, but also are the basis for recreational drugs with euphoria and stimulant properties, such as amphetamines, BZP, MDMA [rather, ecstasy, as noted above], and TFMPP, along with all the negative side effects of these drugs (no wonder I was hallucinating during my acute reaction). So now we have a toxic neuromuscular agent with amphetamine/ecstasy-like effects (piperazine), along with a toxic iodine displacer (fluorine), attached to a chemotherapeutic agent with an intracellular, intranuclear, and intra-mitochondrial genotoxic mechanism of action (quinolone) – a synthetic, fluoridated, neurotoxic, genotoxic chemotherapeutic poison masquerading as an antibiotic and being given en masse to the human and animal population.”

Fluoroquinolones “are known to non-competitively inhibit the activity of the neurotransmitter, GABA, thus decreasing the activation threshold needed for that neuron to generate an impulse.” (source, source, source) Fluoroquinolones have also been shown to have similar effects on GABA neurotransmitters as benzodiazepine withdrawal (source).

The inhibition of GABA by the piperazine part of fluoroquinolones is a plausible, even likely, mechanism for the many horrible psychiatric effects that people suffer from after taking fluoroquinolones.

In a survey of 94 people who experienced adverse reactions to Levaquin/levofloxacin, a fluoroquinolone antibiotic, 72% reported experiencing anxiety, 62% reported depression, 48% reported insomnia, 37% reported panic attacks, 33% reported brain fog and/or cognitive impairment, 29% reported depersonalization and/or derealization, 24% reported thoughts of suicide and 22% reported psychosis. (source, source)

More than 20 million prescriptions for fluoroquinolones are given out in the U.S. each year. If even only 1% of the people who take fluoroquinolones experience a psychiatric adverse-reaction, that’s still a lot of people whose minds aren’t their own, who are suffering from depression, anxiety, insomnia and worse, because of an antibiotic that is made with a chemical that has amphetamine/ecstasy-like effects.

These effects can have tragic consequences, as can be seen in the video and article mentioned above about Shea McCarthy.

Psychiatric adverse effects of prescription drugs are serious, and they should be taken seriously. They are not a choice. No one would choose to feel psychotic, or even anxious.

There are many plausible mechanisms through which fluoroquinolones can cause psychiatric problems. Perhaps it is time that the psychiatric effects of fluoroquinolones become more widely recognized.

Why Athletes Should Never Take Fluoroquinolone Antibiotics

chris-fqwall

No one should take fluorouqinolone antibiotics unless there is no other alternative and one is in a life-or-death situation. Athletes in particular should be aware of the harm that fluoroquinolones can do, and they should avoid them if at all possible. Athletes should know that their athletic abilities, and even their lives, can be taken from them by fluoroquinolone antibiotics.

Please read, and share, this post:

Fluoroquinolone Toxicity Video of News Stories

Chris Jones made this WONDERFUL video –

https://www.youtube.com/watch?v=XgTiGhFrBgc

He posted it with the following instructions:

Over the last year there have been many news stories about fluoroquinolones. I made a video to highlight these stories. I am asking you all to please help me do a few things.

1. Watch it many times to get the view count up.

2. Like the video.

3. Leave a comment on it in YouTube. ( the news stories comments helped a lot, but once the story is gone it is a lot harder for new people to see them). These comments will help people who get floxed years from now.

4. Share as many time as possible.

After the comments and views are high. I will be emailing it to major news stations, talk shows, politicians, the FDA, and I recommend you send it to the doctor who rx you this poison.

Thank you everyone who had the courage to do a news story. I know how hard it was. And thank you to everyone behind the scenes who put them together.
