dangers of Levaquin

The Fluoroquinolone Time Bomb – Answers in the Mitochondria

16210 views

Two of the more perplexing features of Fluoroquinolone Toxicity (an adverse reaction to a fluoroquinolone antibiotic – Cipro/Ciprofloxacin, Levaquin/Levofloxacin, Avelox/Moxifloxacin or Floxin/Ofloxacin) are delayed reactions and tolerance thresholds. Both of these features of Fluoroquinolone Toxicity can be explained by noting that fluoroquinolones have been shown to damage mitochondria and cause oxidative stress, and that delayed onset of a disease state, as well as tolerance thresholds, are features of illnesses brought on by pharmaceutical induced mitochondrial damage and oxidative stress.

Delayed Reactions and Tolerance Thresholds with Fluoroquinolone Reactions

By “delayed reactions” I mean that adverse reactions to fluoroquinolones can occur weeks, months or even years after administration of the fluoroquinolone has stopped.  For the lawsuit filed by Public Citizen on behalf of patients who tore or ruptured tendons after taking a fluoroquinolone, (a suit that prompted the addition of the black box warning on all orally and IV administered fluoroquinolones) notes that “Fluoroquinolones, including CIPRO®, are associated with an increased risk of tendinitis and tendon rupture in all ages. This risk is further increased in older patients usually over 60 years of age, in patients taking corticosteroid drugs, and in patients with kidney, heart or lung transplants”. Tendon tears and ruptures that occurred within one year of the patient taking the fluoroquinolone were accepted as being related to the patient’s fluoroquinolone use. Patient reports have noted that new adverse symptoms of fluoroquinolone toxicity have occurred years after administration of the fluoroquinolone has ceased.

Many patients also experience a tolerance threshold for fluoroquinolone use.  A patient can tolerate fluoroquinolones well, experiencing few or no side-effects, until his or her threshold is reached.  After the patient’s tolerance threshold is reached, multisymptom systemic illness ensues. This patient’s story, found on the Fluoroquinolone Wall of Pain, illustrates the issue of tolerance thresholds:

On April 15, 2013 I was prescribed Avelox. I had been on this drug many times for chronic sinus infections. This time was different. Within 10 minutes of the first dose I went into anaphylaxis. I stopped breathing, had numerous convulsions and two grand Mal seizures. Since that day I have suffered with seizures, convulsions, tremors, debilitating fatigue, muscle weakness, vision loss, severe neuropathic pain, vomiting, nausea, lack of appetite, tendon, and vein problems.

This patient tolerated Avelox (moxifloxacin – a fluoroquinolone) well until her tolerance threshold was reached. Once her tolerance threshold was reached, she experienced multi-symptom systemic illness.

I personally experienced both a delayed reaction to Cipro/Ciprofloxacin (also a fluoroquinolone) and a tolerance threshold for it. I took 7 500-milligram pills of Cipro in 2009 without notable incident. I was even able to hike the entire 500-mile Colorado Trail in 2010 (no peripheral neuropathy or weakness were present at that time). When I took 7 more 500-milligram pills in 2011 I experienced a severe adverse reaction that began two full weeks after I was done taking the pills. I experienced multiple musculoskeletal (I couldn’t walk more than a block) and nervous system symptoms (I lost my memory and reading comprehension), and I would describe the reaction as feeling like a bomb had gone off in my body.

Fluoroquinolone Time Bomb: It’s All About the Mitochondria

My experience of a delayed onset of systemic health issues after having previously tolerated Cipro/Ciprofloxacin well, is typical of diseases that are brought on by a pharmaceutical causing mitochondrial dysfunction. (Multiple journal articles have noted that fluoroquinolones cause mitochondrial damage and oxidative stress.)

In “Mechanisms of Pathogenesis in Drug Hepatotoxicity Putting the Stress on Mitochondria” it is noted that:

…damage to mitochondria often reflects successive chemical insults, such that no immediate cause for functional changes or pathological alterations can be established. There is indeed experimental evidence that prolonged injury to mitochondria, such as that which typifies oxidative injury to mitochondrial DNA or to components of the electron transport chain (ETC), has to cross a certain threshold (or a number of thresholds) before cell damage or cell death becomes manifest.

Each time mitochondria is injured, the patient gets closer to his or her personal tolerance threshold for mitochondrial damage. Once the threshold is crossed, cell damage and apoptosis occur – which manifest themselves in various states of illness.

It is further explained in “Mechanisms of Pathogenesis” that:

…approximately 60% of mitochondrial DNA must be deleted from the mouse genome before complex IV activity is compromised and serum levels of lactate are elevated. This non-linear response can be explained upon consideration that the molecules that subserve mitochondrial function (e.g., mitochondrial DNA, mRNA, and ETC proteins) are present in excess of amounts required for normal cell function. This reserve (or buffering) capacity acts as a protective mechanism; however, at a certain stage of damage, the supply of biomolecules needed to support wild-type mitochondrial function becomes compromised.

The lay person’s summary of the above excerpts is that we have excess mitochondrial DNA and that excess mitochondrial DNA keeps each of us from developing a systemic multi-symptom illness whenever mitochondrial DNA is adversely affected (many pharmaceuticals and environmental toxins adversely affect mitochondrial DNA). However, when mitochondrial DNA is depleted sufficiently, cellular dysfunction, oxidative stress and cell death, ensue.

Multiple studies have noted that fluoroquinolones deplete mitochondrial DNA (here, here and here).  When enough mitochondrial DNA are depleted, adverse reactions that are systemic and include multiple symptoms simultaneously, occur.

Multi-Symptom Reaction: Look to Mitochondrial Damage

It is often difficult for the patient who is experiencing a systemic multi-symptom illness to connect his or her illness to the mitochondria damaging drug or toxin that hurt him or her because of the time delay between the cause (mitochondria damaging chemical) and the effect (bomb going off in body and mind). Though the delayed onset of fluoroquinolone toxicity and mitochondrial dysfunction symptoms are noted in many articles (here, here), the reason for the delayed onset of symptoms is not known.  In “Mechanisms of Pathogenesis” it is hypothesized that “an initial adaptive response was followed by a toxic response” when cells are exposed to a mitochondria damaging chemical. Perhaps the delay in adverse reaction onset is due to a toxic response taking time to develop.

Many pharmaceuticals damage mitochondria. Bactericidal antibiotics (including fluoroquinolones), Statins, acetaminophen, some chemotherapy drugs, vaccines, and many others, cause mitochondrial dysfunction, oxidative stress and cell death. Mitochondrial dysfunction and oxidative stress are connected to a variety of ailments, from chronic fatigue syndrome to Alzheimer’s disease and obesity. However, the FDA and other drug regulatory agencies have systematically ignored damage to mitochondria caused by pharmaceuticals and “mitochondrial toxicity testing is not required by the US FDA for drug approval.”

The recognition of delayed adverse reactions and tolerance thresholds for mitochondrial damaging drugs and vaccines will go far in helping both doctors and patients to recognize mitochondrial damage related adverse drug reactions (and adverse vaccine reactions). Once the reactions are recognized, perhaps some pressure can be put on the FDA and/or the pharmaceutical companies to test how drugs affect mitochondria before they are released onto the market. After all, mitochondrial damage and oxidative stress are causally related to almost every chronic illness.  It would be nice if doctors, those in the pharmaceutical industry, the FDA regulators, and others, recognized the harm that drugs do to mitochondria, and the symptoms of iatrogenic mitochondrial dysfunction.

Don’t Take Cipro, Levaquin or Avelox If….

7959 views

There is a huge range in how people react to fluoroquinolone antibiotics (Cipro/Ciprofloxacin, Levaquin/Levofloxacin, Avelox/Moxifloxacin and Floxin/Ofloxacin). Some people take fluoroquinolones repeatedly and never experience an adverse reaction. Some people are left bed-bound after one pill, or one prescription. Some people take a full fluoroquinolone prescription without incident at one time in their life, then, when they take a second (or third, or fourth) prescription, their body goes hay-wire. Some people have a sudden and severe adverse reaction, where they are unable to move or think after previously being fine, and other people have a gradual onset of symptoms where they damage tendons or develop neuropathy slowly, over time.

What determines how a person reacts to fluoroquinolones? The black box warning label on fluoroquinolones states that, “risk (of tendinitis) is further increased in older patients usually over 60 years of age, in patients taking corticosteroid drugs, and in patients with kidney, heart or lung transplants.” But people who fit into those categories aren’t the only people who are hurt by fluoroquinolones. I didn’t fit into any of those categories. I was 32, athletic, strong, not on any medications, etc. when I was sickened by Cipro. I was healthy. But fourteen 500 milligram pills of Cipro (half taken in 2009 without incident and half taken in 2011 with a sudden severe adverse reaction) were enough to cause my body and mind significant harm.

I must have had risk factors that made me susceptible to fluoroquinolone toxicity though, because Cipro made me quite sick. I’m honestly not sure what those factors are (no one knows – or at least they aren’t publishing papers about it if they do). Perhaps those who are hurt by fluoroquinolones have depleted liver enzymes and therefore they aren’t able to metabolize drugs like people who have more robust supplies of drug metabolizing enzymes. Perhaps people who suffer from fluoroquinolone toxicity are depleted of cellular magnesium, as magnesium has been shown to have protective effects on cells that are exposed to fluoroquinolones. Perhaps the microbiome of those who are hurt by fluoroquinolones is depleted of good bacteria and an overwhelming number of bad bacteria in the gut leads to many of the symptoms of fluoroquinolone toxicity. Perhaps there are some people who are genetically predisposed toward having an adverse reaction to fluoroquinolones. As with everything, there is a mix of genetics and environment that goes into how the body reacts when faced with a chemical onslaught. Human bodies are unbelievably complex and multifaceted; once individual differences are considered, the complexity becomes mind-boggling.

Customizing medicine is difficult. The entire human genome, though sequenced, has not yet been mapped out. We are not at a point yet where we can easily and inexpensively test genes and interpret the results of genomic tests.

Genes aren’t the only things that determine how a person reacts to a drug. The microbiome also plays an important role in determining drug metabolism. Per an article entitled, Role of Intestinal Microflora in Xenobiotic-induced Toxicity, “individual differences in the intestinal microflora may result in individualized xenobiotic (a chemical or substance that is foreign to an organism or biological system) toxicities.” The differences in the bacteria in our gut make a difference in how drugs are metabolized. As the microbiome is changed, through drugs – especially antibiotics, the reaction of the individual patient to formerly well tolerated drugs, can change.

Until customizing medicine to the individual becomes feasible, what are doctors supposed to do to prevent their patients from having a dangerous adverse reaction to a drug? Drugs with potentially devastating adverse effects could be avoided entirely unless they are necessary to save a life. This is the policy that I would like to see applied to fluoroquinolones. (The cellular damage that fluoroquinolones inflict make their use inappropriate for infections that are not life-threatening.) Unfortunately, prudence in regards to prescribing fluoroquinolones is not the current trend. In 2011, 23.1 million prescriptions for fluoroquinolones were written in the U.S., and despite the 43 page warning label that comes with Cipro/Ciprofloxacin, fluoroquinolone toxicity is denied by many physicians. As much as I would like to cut the number of fluoroquinolone prescriptions by 90%, the entire medical establishment is not yet listening to me and others who are screaming about the pain and suffering caused by fluoroquinolones. To reduce the number of people hurt, either a study or news story must induce a paradigm shift enabling all doctors to see that fluoroquinolones are vastly more dangerous than penicillin, or patients (especially those in the risk categories listed below) must ask their doctors to not prescribe them.

Though the true risk factors for fluoroquinolone toxicity (genetic, enzyme and microbiome markers) are not yet established, there are some groups of people who are at higher risk of an adverse reaction than others. They should never be given fluoroquinolones. Those groups are:

  1. People who have had an adverse reaction to a fluoroquinolone in the past. Despite the fact that all of the warning labels for fluoroquinolones state that they should not be given to people with a history of hypersensitivity to fluoroquinolones, the recommendation that they be avoided is often ignored. This is the case because people often don’t realize that they are having a mild adverse reaction to a fluoroquinolone. Who would think that muscle twitches, insomnia, urgency when urinating or loss of endurance would be related to the administration of an antibiotic? The connection is so bizarre that it is often not recognized. A list of warning signs that your body has reached its threshold for fluoroquinolones can be found here: Warning Signs of Fluoroquinolone Toxicity.
  2. Athletes. It is well documented and known that fluoroquinolones degrade the structure of tendons. They “exert a toxic effect not only on tendons but also on cartilage, bone, and muscle,” per a Mayo Clinic affiliated article entitled Musculoskeletal Complications of Fluoroquinolones: Guidelines and Precautions for Usage in the Athletic Population. Further information about why the Mayo Clinic researchers note that, “Athletes should avoid all use of fluoroquinolone antibiotics unless no alternative is available” can be found here: Deciphering the Pathogenesis of Tendonopathies: A Three Stage Process.
  3. People on steroids. Steroids are contraindicated with fluoroquinolones. As is noted in the Cipro/Ciprofloxacin warning label, people who are on corticosteroids are at an increased risk of tendonitis when administered fluoroquinolones. In addition to the increased risk of tendon damage, the combination of steroids and fluoroquinolones can increase the risk of development of a deadly glabrata fungal infection.
  4. People who need to take NSAIDs regularly. NSAIDs, and other drugs that contain a carboxylic acid molecule, are contraindicated with fluoroquinolone toxicity. Patients suffering from fluoroquinolone toxicity have reported adverse reactions to NSAIDs even weeks or months after they have stopped taking fluoroquinolones. The adverse interaction between fluoroquinolones / fluoroquinolone toxicity and NSAIDs is likely because of the formation of poisonous acyl glucuronides. Articles describing this process can be found on Fluoroquinolone Links and Resources.
  5. Immunocompromised individuals. Fluoroquinolones, and other broad spectrum antibiotics, kill good bacteria along with harmful bacteria. When the good bacteria in the gut are wiped out, they can no longer keep the bad bacteria, or fungal infections, in check. Fungal infections can take over a person’s body and they can be deadly. This can happen with people who have healthy immune systems. For people with already compromised immune systems, vulnerability to fungal infections may be increased. Per an article in Life Extension Magazine, “Anyone can acquire a fungal infection, but the elderly, critically ill, and individuals with weakened immunity, due to diseases such as HIV/AIDS or use of immunosuppressive medications (such as corticosteroids), have a higher risk.”
  6. People with mitochondrial dysfunction. Per an article entitled Mitochondrial Reactive Oxygen Species Control T Cell Activation by Regulating IL-2 and IL-4 Expression: Mechanism of Ciprofloxacin-Mediated Immunosuppression, “ciprofloxacin was also shown to deplete the mitochondrial DNA (mtDNA) content, thus leading to mitochondrial dysfunction and retarded cellular growth.” Ciprofloxacin and other fluoroquinolones damage mitochondria. Those with preexisting mitochondrial dysfunction will suffer more as their mitochondria are further damaged.
  7. Children. Fluoroquinolones have been shown to degrade cartilage in juvenile animals and, for this reason, are generally considered to be contraindicated in the juvenile population. Unfortunately, children are still prescribed fluoroquinolones by pediatricians who are unaware of the severity of adverse reactions to fluoroquinolones.

Until medicine is more individualized and every factor that makes a person more or less susceptible to experiencing an adverse reaction to a drug can be tested before that drug is administered, everyone who takes a fluoroquinolone is at risk of experiencing an adverse reaction. The best way to protect oneself from fluoroquinolone toxicity is to not take a fluoroquinolone. Though there are some risk factors that make some groups of people more susceptible to experiencing a severe adverse reaction to fluoroquinolones than others, there is no guarantee that not fitting into one of those groups will ensure your safety. With that noted, the people who fit into any of the seven categories listed above should avoid fluoroquinolones whenever possible.

Cipro, Levaquin and Avelox are Chemo Drugs

20892 views

When I first heard people referring to fluoroquinolone antibiotics (Cipro, Levaquin, Avelox, Floxin and a few others) as “chemotherapy drugs,” I thought that they were exaggerating or incorrect.  After all, fluoroquinolones are used to treat urinary tract infections, traveler’s diarrhea, anthrax, and other bacterial infections, not cancer. But then I started to do some research into how fluoroquinolones work and I discovered that they cause mitochondrial damage, which leads to oxidative stress and cell death (1, 2), they interfere with the DNA replication process of mitochondria (3), they disrupt tubulin assembly (4) and that they are being investigated for their tumor killing abilities (5, 6).  I also found that all other drugs that have the same mechanism for action as fluoroquinolones – topoisomerase interrupters (FDA warning label, 7) (topoisomerases are necessary for proper DNA replication) – are used as chemotherapy drugs – topotecan, amsacrine, etoposide, etc.  Fluoroquinolones are, truly, chemotherapy drugs – they just happen to be used as popular antibiotics. They can kill cancerous tumor cells because, in addition to killing bacterial cells, they also kill eukaryotic cells (8, 9).

Use of Fluoroquinolones for Cancer Treatment is Appropriate

There are almost certainly some legitimate and reasonable uses for fluoroquinolones as chemotherapy drugs (10).  As tumor killing agents, they may save lives of those with cancer.  Unfortunately, they’re not as targeted as the chemotherapy drugs that are currently in use.  Many chemotherapy drugs on the market specifically target quickly dividing cells – like tumor and hair cells; so they kill the cancer cells while leaving most other cells intact. Fluoroquinolones aren’t that precise. They indiscriminately kill cells throughout the body – including neurons and lymphocytes (11) (immune system cells).  The mitochondrial DNA (mtDNA) replication process is disrupted by fluoroquinolones (3), and the disruption of that process leads to mitochondrial damage, oxidative stress and cell death (12).  Fluoroquinolones are effective cell killers, but because they are indiscriminate cell killers, they are a step backward in chemotherapy drug technology.

Lousy Chemo Drugs?  Let’s Use Them as Antibiotics for Everyone!

Because they are not particularly good chemotherapy drugs, fluoroquinolones are rarely used for the purpose of killing cancer cells.  Instead, they are used as antibiotics. They are prescribed to treat sinus infections, bladder infections, strep throat, and they are even prescribed prophylactically (typically for future treatment of travelers’ diarrhea) when no infection is present. They kill bacteria, and are effective antibiotics, but they also damage mitochondria and destroy cells and therefore have many of the same side-effects as chemotherapy drugs, because, as noted above, they are chemotherapy drugs.

Side-Effects of Fluoroquinolones, and Other Chemotherapy Drugs

Some of the side-effects that fluoroquinolones share with chemotherapy drugs are (13, 14, 15, 16 and the FDA warning label for Ciprofloxacin – the warning labels for Levofloxacin and the other fluoroquinolones are similar):

  • Exhaustion / Loss of energy / Fatigue
  • Brain-fog / Loss of cognitive abilities
  • Anemia
  • Muscle Loss / Wasting
  • Neuropathy / Peripheral Neuropathy / Fibromyalgia

Additionally, Fluoroquinolones destroy connective tissue, especially tendons.  (17, 18, 19)

When one thinks of fluoroquinolones as chemotherapy drugs as opposed to antibiotics (yes, they do kill bacteria, but they should not be thought of in the same terms as benign drugs like penicillin and cephalosporins), many aspects of adverse reactions to fluoroquinolones make sense. Like several other chemotherapy drugs, there is a tolerance threshold (and/or lifetime limit) for fluoroquinolones (20, 21). Many people don’t react to their first dose of a fluoroquinolone. Rather, they tolerate the drugs up to a point – then they can no longer tolerate them and Fluoroquinolone Toxicity results. For fluoroquinolones, and possibly for other chemotherapy drugs, this tolerance threshold issue is because mitochondria are able to withstand a certain amount of damage before a disease state ensues. It is only after the tolerance threshold for damage is crossed that mitochondria stop adapting to harmful stimuli and a disease state ensues. (22)

Cellular Damage from Chemo Drugs can Lead to Cancer – Isn’t that Ironic?

Destruction of mitochondrial DNA can result in mitochondrial dysfunction and oxidative stress – which lead to apoptosis and necrosis of cells (23). When this occurs, a multi-symptom, chronic, autoimmune-disease-like reactions can occur (24, 25). However, if cell damage occurs but the cell does not die, but rather replicates the DNA errors, cancer can result (26, 27, 12).

Additionally, drugs that inhibit CYP450 liver enzymes [Cytochrome P450 enzymes metabolize xenobiotics and foreign chemicals from the body. (28)] leave people more susceptible to cancer-causing pathogens (29). Fluoroquinolones inhibit multiple CYP450 enzymes (30, FDA warning label). How ironic, isn’t it? Cancer can result from chemotherapy drugs. And when it is understood that fluoroquinolones are chemotherapy drugs that damage mtDNA and cause oxidative stress and apoptosis/necrosis, the irony of chemotherapeutic drugs causing cancer becomes horrifying, as opposed to thought-provoking.

Cellular Harm Results from Willful Ignorance About the Effects of Fluoroquinolones

There are articles that say that fluoroquinolones have an excellent safety record. (31)  None of those articles look at the effects of these drugs on the mitochondria – the depletion of mtDNA, the oxidative stress that results from damaged mitochondria, the DNA damage that is caused by the oxidative stress, etc.  In not looking at mitochondria, those articles are looking at the wrong things and they in no way negate the findings of the articles that note the deleterious effects of fluoroquinolones on human cells.

While it may be appropriate to give drugs that disrupt the process of mitochondrial DNA replication, have horrific side-effects and cause indiscriminate cell death, to people who are have cancer, it is absurd to give them to people who are healthy other than a minor infection. Even for major, difficult to treat infections, fluoroquinolones should be the drugs of last resort because of their effects on mitochondria. (1, 32)  Chemotherapy drugs should be used exclusively in life-or-death situations. They should not be used frivolously or without true informed consent of the patient, or without awareness of the consequences of the drug on the part of both the physician and the patient. Protocols should be in place for ensuring that they are used appropriately and that all parties are aware of the consequences of the drugs.

Sadly, appropriate informed consent around fluoroquinolones involves a complete shift in how physicians and patients alike think about them. In order for the risks of taking fluoroquinolones to be properly acknowledged, all parties involved need to see, and acknowledge, that fluoroquinolones are chemotherapeutic drugs that cause mitochondrial destruction and cell death, and that they should not be used lightly. But because fluoroquinolones have been given out frivolously – 26.9 million prescriptions for oral and IV fluoroquinolones were given out in 2011 alone (33) for simple infections, I don’t foresee the shift in how they are perceived as an easy one. It must involve many doctors admitting that they have been prescribing these drugs incorrectly for decades, that they have been wrong about the severity of adverse effects, and that they have been misled about the risks of fluoroquinolones.

The Effects of Drugs on Mitochondria are Systematically Disregarded

It should also be noted that the effects of drugs on mitochondria are systematically disregarded. Mitochondrial function, and drug-induced dysfunction, is important to all areas of human health.  An article published in Molecular Nutrition and Food Research entitled Medication Induced Mitochondrial Damage and Disease” noted that the effects of drugs on mitochondria are ignored by both the drug companies and the FDA when reviewing drug safety. Because of this omission in review and oversight, human mitochondrial DNA have been repeatedly damaged by fluoroquinolones and other pharmaceuticals. The consequences of this are, as of yet, unknown. (Though it should be noted that mitochondria and the signals that they produce influence gene expression (35) and that an article published in Nature in July, 2013 entitled “Topoisomerases Facilitate Transcription of Long Genes Linked to Autism” showed that topoisomerase interrupting chemotherapy drugs effect the expression of genes linked to Autism.) We can only hope that the FDA’s failure to force drug reviewers to look at the effects of drugs on mitochondrial DNA isn’t horribly consequential.

Open Letter to Pharmacists Prescribing Fluoroquinolones – You Know!

3819 views

Dear Pharmacists,

You know about the dangers of fluoroquinolone antibiotics. You know that Cipro, Levaquin, Avelox and the other fluoroquinolones can cause central nervous system damage that can show up as anxiety, depression, memory loss, depersonalization, loss of intellect and social connectedness, suicidal ideation, etc. You know that fluoroquinolones can cause permanent destruction of all the connective tissue in a person’s body, their tendons, ligaments, fascia and cartilage. You know that adverse reactions to fluoroquinolones can be delayed and that stopping the medication will do nothing to stop its path of destruction.  You know that fluoroquinolones are contraindicated with NSAIDs and steroids. You know that they should NEVER be prescribed or administered to anyone under the age of 18.

You are pharmacists. Your expertise is in pharmaceuticals.  You have studied the chemical structure of fluoroquinolones and you know their effects, both good and bad.  You know that they are dangerous drugs that should only be used in life-or-death situations.  You know that they are over-prescribed. You know that they can have DEVASTATING adverse effects.  YOU KNOW.

Yet you continue to hand them out.  You continue to fill prescriptions with no more warning to the patient than a slip of paper in the bag that contains the poison that may shake their world.  You tell them that their infection will go away when they take the Cipro, Levaquin or Avelox.  The infection will go away but you FAIL to warn them that it may be replaced with chronic conditions that mirror autoimmune diseases, that their mental health may never be the same again, that they may never be the athletic, healthy person that they used to be.

You know that fluoroquinolones should NEVER be given to children. Yet you fill prescriptions for eye and ear drops containing fluoroquinolones for children, even BABIES.  You hand poison over to a mother with a crying 11 month-old child with an ear infection, knowing that the Cipro ear drops will get rid of that child’s infection, but that it may fry their little brain. You know. And you don’t protect the children.

You say that it’s the doctor’s job to know what he or she is prescribing, but you know that they have no clue about the dangers of fluoroquinolones. They disregard the warnings of side-effects on the drug labels, thinking that all drugs have side-effects and that they all should be disregarded because the side-effects listed are arbitrary.  There is nothing arbitrary about the litany of side-effects included with prescriptions of Cipro, Levaquin or Avelox.  You know this to be true, but the doctors don’t.  Their crime is one of willful ignorance and arrogance. They refuse to listen to anyone outside of their ranks, including you (and that’s another problem). They are ignorant, possibly through their own fault.  But you are not ignorant. You know about the dangers of fluoroquinolones. You know.

Doctors may not listen to you, but you can still do something about this moral atrocity.  Please, please, please STOP giving out these drugs. You are the gate-keepers. You can keep patients from poisoning themselves, or worse, poisoning their children. You can refuse to fill those prescriptions. You can tell doctors that they MUST follow their Hippocratic Oath and prescribe a safer antibiotic in non-life-threatening situations. You can ensure that all patients who walk away from your counter with a prescription for a fluoroquinolone have real INFORMED CONSENT. The Hippocratic Oath and Informed Consent are indescribably important. They are the moral bedrocks of the medical system, yet they are being disregarded. You can reinstate them in their appropriate place, at the top of the consciousness of every patient who deals with the medical system. You can and you should, yet you don’t.

You, as an individual, have the power to stop filling these prescriptions. You have the power to talk to the doctors that you work with, to inform them that fluoroquinolones are dangerous drugs. You have the power to talk to your patients and ensure that they have the information that they need to make a decision with true informed consent.  You have that power. Please use it to make the world a better place.

You, as a group, have the power to change the way that all drugs are viewed. You can make sure that a protocol of careful examination and active warnings to patients for all drugs that are truly dangerous is followed when prescribing and filling prescriptions of drugs with serious side-effects. You can pressure the FDA into making sure that the side-effects listed on a drug insert are real and not arbitrary so that they are actually paid attention to.

Please be moral. Do the right thing. Please be ethical. Know that your actions have consequences. They matter. Your decision about whether or not to fill a prescription of Cipro, Levaquin or Avelox can make a difference in a person’s life.

I know that the tone of this letter is scolding. Please know that my intention is not to make you feel like a horrible person, my intention is to ask you to be a better, more empowered, more ethical person.  If that is not possible, I ask you, I beg of you, please just STOP filling prescriptions of fluoroquinolones for children. They need your protection. They will thank you by living a full life without the chronic illness that plagues people who have been adversely effected by fluoroquinolones. Please, do what you can. Please do what’s right.

Thank you,

P.S. – If you’re pleading ignorance, let me ask you this question – Would you give your child a fluoroquinolone?  If your answer is no, YOU KNOW.

What Do Fluoroquinolone Antibiotics Have in Common With Gardasil?

6849 views

Horrific side effects that are generally unrecognized by medical practitioners, that’s what these medications have in common. Gardasil Week just ended on Hormones Matter. It made me realize how many bad drugs are on the market. I had an adverse reaction to a fluoroquinolone antibiotic, Cipro, and my life changed forever. Reading the Gardasil stories, I noticed similarities amongst the adverse reactions of the fluoroquinolone antibiotics, Cipro, Levaquin and Avelox and the adverse reactions to Gardasil; both are massive, system-wide and go generally unnoticed by modern medicine.

I have to admit, I’m a bit scared about writing this post. I don’t want to be labeled as “anti-vaccine” and demonized as such. I’m not anti-vaccine. Vaccines have saved thousands of lives throughout human history. Even though an antibiotic hurt me, I’m not anti-antibiotic either. Like vaccines, antibiotics have saved thousands, possibly millions of lives.  Vaccines and antibiotics together account for so much good in modern medicine that it has become almost sacrilegious to question or criticize them – as if in questioning them one negates the lives that have been saved by them.

Rogue Players

Unfortunately, some rogue players have entered both the vaccine and the antibiotic fields; Gardasil in the vaccine market and the fluoroquinolone antibiotics, Cipro, Levaquin and Avelox, in the antibiotic market. Whether the benefits outweigh the risks of these drugs and/or whether these drugs are being used properly is a question that should be asked. Unfortunately, questioning a vaccine or antibiotic leads many to a knee-jerk reaction. Often the injured individual is accused of being anti-vax or anti-antibiotic. It is as if even asking whether or not these drugs are being properly applied and the risk are being properly assessed, is offensive;  as if, in acknowledging that there are side-effects that may not outweigh the benefits for these particular drugs, you are trying to annihilate the whole class of treatments.

I’m not, in any way shape or form, proposing that we get rid of either vaccines or antibiotics. But it would be more than nice, it would be the right, just, empathetic, loving thing to do, to listen to the stories of those who have been hurt by Gardasil or fluoroquinolones, and to explore whether or not they are the right tools to use for accomplishing what we want to accomplish – the limiting of disease and infection. Sticking one’s head in the sand and insisting that all things that come out of the pharmaceutical industry are good and pro-science is a faith-based position that is, frankly, incorrect.

People are being hurt by both Gardasil and fluoroquinolne antibiotics. Disabling, ruinous effects are coming from both of these drugs. Their lives go from normal, with nothing wrong with them in the case of those being treated by Gardasil, or having possibly only a minor infection, in the case of those prescribed fluoroquinolones, to a life of suffering with chronic health problems. This isn’t right. It’s not okay. There is nothing that is okay about turning a non-existent condition into a chronic miserable condition, or an acute condition that can be cured with mild antibiotics, and turning it into a chronic syndrome that causes pain and suffering for years to come.

Too Severe to be Real?

Reactions to both Gardasil and fluoroquinolones are often delayed, weeks to months, and so severe that they are, ironically, disregarded as absurd or impossible. If hundreds or even thousands people didn’t have similar reactions, this might be a valid argument, but when a lot of people have the same reaction of body-wide breakdown, the connection between the drug and the reaction should be seen as valid and researched as such.

Hiking before Cipro, hiking after Cipro
Greg Spooner had a toxic reaction to Cipro in 2010. Details about his story are listed below.

Maybe the incredulous attitude people display when faced with a severe adverse reaction to a pharmaceutical stems from our preconceptions about what medicines should do or how they should act.  Although, we are all aware of the risk for side-effects, we believe they “should” be mild and treatable. When, in fact, some patients develop severe reactions that are systemic, complex and difficult or impossible to treat. Rather than connecting the system-wide breakdown that the patient experiences to the drug, it is easier to believe that the cause of the person’s problems were something else, or dismiss the patient with a misdiagnosis. Rarely are the illnesses linked to the medications that caused them. When the adverse reactions are so comprehensive, they’re seen as absurd and unlikely. Worse yet, they are considered impossible to treat and often dismissed. Even if a physician recognizes the connection between the medication or vaccine and the system-wide breakdown that develops, there is very little, if anything, he or she can do to treat the syndromes that arise.

But They Save Lives

“But they save lives!” is always the argument that people make in favor of these drugs.  For fluoroquinolones, OF COURSE they save lives!  No one is arguing that they don’t.  But given the severity of the adverse effects caused by fluoroquinolones, their use should be reserved for life or death situations. Unfortunately, fluoroquinolones are used as a first line of defense against urinary tract infections, sinus infections, suspected prostate infections, travelers’ diarrhea, etc., when other, safer drugs are available and are equally effective. Giving people a drug with the potential for severe negative consequences when there are effective alternatives that don’t have the same risks is a violation of the Hippocratic Oath.

Of course, if everyone reacted as badly as I did to Cipro, or as badly as Alexis, Ashley or Nicole did to Gardasil, these drugs would be taken off the market.  Everyone would know that they are dangerous and no one would take them (except, in the case of fluoroquinolones like Cipro, in a truly life-or-death situation where there were no other alternatives). But the fact that not everyone has a horrific adverse reaction to these drugs does not negate the fact that some people do.  (And more people have bad reactions to these drugs than realize it.  Because of the delay in adverse reactions, the fact that they are under-recognized by doctors and thus an incorrect diagnosis is often made, and the absurdity of the reactions being caused by an antibiotic or vaccine, people often fail to make the connection between the cause, fluoroquinolones or Gardasil, and the reaction, a chronic syndrome of pain and destruction.)

Regardless of whether or not policy change comes as a result of the harm caused by Gardasil or fluoroquinolones, the victims of both deserve sympathy and compassion.  They deserve to be able to tell their stories. They deserve to be listened to. I can only hope that the stories are heard.
