Watch Out For Neuropathic Antibiotic Side Effects!


Today's post from collective-evolution.com (see link below) is another powerful argument against taking fluoroquinolone antibiotics (Cipro,Levaquin,Avalox etc), especially if you have or are prone to neuropathic problems. It's astonishing that many doctors are still unaware of the dangers and side effects of these drugs and prescribe them routinely without looking to see whether the patient is at risk. The best advice is to look at the pharmaceutical (not the brand name) name of any antibiotics you are given and check the side effects on the internet (Drugs.com has a reliable and trustworthy reputation in this regard). After that, if you are still worried, discuss it with your doctor with any evidence you might have gathered and ask for an alternative (there are plenty to choose from). Don't just stop taking them or ignore it - rely on your doctor making the right choice in the end.
 


Fluoroquinolone Antibiotics: Are You At Risk?
August 26, 2013 by Lisa Bloomquist. 

Fluoroquinolone antibiotics, Cipro, Levaquin, Avelox, etc. are broad-spectrum antibiotics used to treat a variety of infections, from urinary tract infections to anthrax and everything in between. The first quinolone created was Nalidixic Acid which was discovered by George Lesher in 1962. (Nalidixic Acid was added to the OEHHA prop 65 list of carcinogens in 1998.) Cipro (ciprofloxacin) is a second generation fluoroquinolone patented in 1983 by Bayer, Levaquin (levofloxacin) is a third generation fluroquinolone patented in 1987 by Ortho-McNeil-Janssen (a division of Johnson & Johnson), and Avelox (moxifloxacin) is a fourth generation fluoroquinolone patented in 1991 by Bayer.


Fluoroquinolone Antibiotics – Still on the Market

Of the 30 quinolones that have made it to market since the 1980s, all but 6 have either been removed from the US market or have severely restricted use.

The fluoroquinolone antibiotics that are still on the market are some of the most commonly prescribed antibiotics. Per the FDA, “Approximately 23.1 million unique patients received a dispensed prescription for an oral fluoroquinolone product from outpatient retail pharmacies during 2011,” and “Within the hospital setting, there were approximately 3.8 million unique patients billed for an injectable fluoroquinolone product during 2011.”

When used properly, such as in cases of life-threatening hospital acquired pneumonia, fluroquinolone antibiotics can save lives. 


Fluoroquinolone Antibiotic Side-Effects and Adverse Reactions

When used improperly, fluoroquinolone antibiotics can needlessly cause devastating side-effects. Devastating side-effects can also occur when fluoroquinolone antibiotics are used properly, but the devastation can be justified by weighing it against the alternative – death. In 2001, Dr. Jay S. Cohen published an article on the severe and often disabling reactions some people sustained as a result of taking a fluoroquinolone antibiotic. Dr. Cohen says,

It is difficult to describe the severity of these reactions. They are devastating. Many of the people in my study were healthy before their reactions. Some were high intensity athletes. Suddenly they were disabled, in terrible pain, unable to work, walk, or sleep

Dr. Cohen’s study of 45 subjects suffering from Fluoroquinolone Toxicity Syndrome, a name that I’m pushing for, (without an official name, it is difficult get the word out) showed that they had the following symptoms:


Peripheral Nervous System: Tingling, numbness, prickling, burning pain, pins/needles sensation, electrical or shooting pain, skin crawling, sensation, hyperesthesia, hypoesthesia, allodynia (sensitivity to touch) numbness, weakness, twitching, tremors, spasms.


Central Nervous System: Dizziness, malaise, weakness, impaired coordination, nightmares, insomnia, headaches, agitation, anxiety, panic attacks, disorientation, impaired concentration or memory, confusion, depersonalization, hallucinations, psychoses.


Musculoskeletal: Muscle pain, weakness, soreness, joint swelling, pain, tendon pain, ruptures.


Special Senses: Diminished or altered visual, olfactory, auditory functioning, tinnitus (ringing in the ears).


Cardiovascular: Tachycardia, shortness of breath, hypertension, palpitations, chest pain.


Skin: Rash, swelling, hair loss, sweating, intolerance to heat and\or cold.
Gastrointestinal: Nausea, vomiting, diarrhea, abdominal pain.

When a fluoroquinolone antibiotic triggers a toxic reaction in a person, multiple symptoms are often experienced.


Fluoroquinolone Antibiotic Damage – Technical Aspects

Fluoroquinolones are eukaryotic DNA gyrase and topoisomerase inhibitors very similar to many antineoplastic agents (source). What this means in plain English is that these drugs work the same way as chemotherapeutic drugs; they disrupt DNA and lead to destruction of cells. A recent (2013) study conducted by a team of scientists at the Wyss Institute for Biologically Inspired Engineering at Harvard University Studies showed that Ciprofloxacin, along with a couple of other non-fluoroquinolone antibiotics, causes oxidative stress and mitochondrial malfunction. A 2011 study published in the Journal of Young Pharmacists found that, “There is significant and gradual elevation of lipid peroxide levels in patients on ciprofloxacin and levofloxacin.” They also found that “There was substantial depletion in both SOD (superoxide dismutase, “a free radical scavenging enzyme”) and glutathione levels” and that “On the 5th day of treatment, plasma antioxidant status decreased by 77.6%, 50.5% (and) 7.56% for ciprofloxacin, levofloxacin and gatifloxacin respectively.” The study also notes that administration of fluoroquinolones leads to a marked increase in the formation of Reactive Oxygen Species (ROS) and that “reactive free radicals overwhelms the antioxidant defence, lipid peroxidation of the cell membrane occurs. This causes disturbances in cell integrity leading to cell damage/death.” 


How Many People are at Risk?

The exact rate of adverse reactions to fluoroquinolones is difficult to determine. Studies of adverse reactions to fluoroquinolones have noted that, “During clinical trials, the overall frequencies of adverse effects associated with (fluoroquinolones) to vary between 4.4 and 20%.” Just the fact that the spread is so large, a 15.6% spread in frequency of adverse reactions is a HUGE difference, it implies that the actual occurrence of adverse reactions is difficult to establish or unknown.

With the FDA figures above noting that 26.9 million unique patients were given fluoroquinolones in 2011, if you just take the conservative adverse reaction figure of 4.4%, you’ll get a horrifying number of people with adverse reactions in 2011 alone – 1,183,600 people. 20% of 26.9 million is 5,380,000 people adversely effected. That is scary. Those numbers are truly frightening given the severity of the adverse effects described above.
Fluoroquinolone Toxicity Syndrome

I see fluoroquinolone toxicity everywhere, and even I think that those numbers are high for severe, disabling reactions like mine where multiple symptoms develop simultaneously. Not everyone who has an adverse reaction to a fluoroquinolone has a reaction like mine, or even develops Fluoroquinolone Toxicity Syndrome. Many people have milder reactions. Milder symptoms include any one of the symptoms listed above as well as diarrhea, vomiting, mild tendinitis, decreased energy, painless muscle twitches, memory loss, urgency of urination, or any number of reactions that the body may have to a massive depletion of antioxidants and increases in lipid peroxide levels and reactive oxygen species production.

Even though severe adverse reactions to fluoroquinolones antibiotics can be painful and disabling for years, many (possibly most, but certainly not all) people recover from Fluoroquinolone Toxicity Syndrome with time. I anticipate that I will be fully recovered 2 years after my reaction started. Sadly, there are some people who don’t recover. They suffer from chronic pain, disability, impaired cognitive abilities, etc. permanently.

It is absurd, to say the least, that an acute problem, an infection, that can easily be taken care of with administration of an antibiotic that is not a fluoroquinolone, is converted into a chronic problem, a syndrome that can disable a person for years, by a prescription ANTIBIOTIC, used as prescribed. In my case, a urinary tract infection that could have likely been taken care of with macrobid or even cranberry juice and d-mannos, was treated with Cipro which left me unable to do many physical and mental tasks that I had previously been able to do with ease. It’s a crazy, absurd situation. It’s absurd and it’s wrong.


Some Antibiotics are More Dangerous than Others

The bottom line is that these popularly prescribed antibiotics are dangerous drugs that have caused thousands of people to suffer with a myriad of maladies. Undeniably, they have their place, in treating life-threatening infections. Unfortunately, they are not being reserved for use in life-threatening situations and people are being hurt after taking them for simple sinus, urinary tract, bronchial and prostate infections. A strict and rigorous protocol needs to be established to limit the damage that they cause; because it’s not right to maim and disable people to treat their sinus infections.

Another Suspect Fluoroquinolone Antibiotic May Cause Neuropathy


Today's post from aboutlawsuits.com (see link below) is another one in the growing row about fluoroquinolone antibiotics (in this case Avelox) and their potential for causing nerve damage. It's worth bearing in mind that fluoroquinolones are by far the commonest antibiotic prescribed in the USA but nobody can ignore the evidence that shows that they are a danger for people susceptible to nerve damage and even more damaging for those who already have it. Even the FDA has insisted that the industry display clear warnings on the packaging of these drugs and yet doctors still prescribe them widely, either through lack of knowledge or lack of professional attention to detail. The problem is that this class of antibiotics comes under many brand names and people aren't always aware that the tiny print reveals that they are fluoroquinolones (and sometimes not even that). If you have neuropathic problems and/or immune system illnesses, you really need to have a serious discussion with your doctor as to whether these are the right drugs for you, especially as there are enough alternatives available.

Avelox Lawsuit Filed Over Peripheral Neuropathy Risk Written by: Irvin Jackson September 26, 2014

According to claims raised in a recently filed product liability lawsuit against Bayer and Merck, consumers and the medical community were provided inadequate warnings about the link between Avelox and peripheral neuropathy for years, which allegedly left a Tennessee woman with irreversible and permanent nerve damage.

The complaint (PDF) was filed last month by Sherri Kellerman, in the U.S. District Court for the Northern District of California.

Kellerman indicates that she developed peripheral neuropathy from side effects of Avelox (moxifloxacin), which is a popular antibiotic that is part of a class of medications known as fluoroquinolones. Other medications in the same class include the blockbuster antibiotics Levaquin and Cipro.

Fluoroquinolone Antibiotic Failure to Warn

The case joins a growing number of antibiotic peripheral neuropathy lawsuits being pursued nationwide, which all involve similar allegations that makers of fluoroquinolones provided false and misleading information about the risk of permanent nerve damage that may result from use of the medications.

Peripheral neuropathy involves damage to the nerves, which may impair sensation, movement and other aspects of health. Symptoms may include pain, burning, tingling, numbness, weakness and sensitivity to light touches, temperature and motion in the arms and legs.

Until last year, the peripheral neuropathy warnings provided with Avelox suggested that the problems were “rare” and failed to adequately disclose that users may be left with irreversible nerve damage, according to allegations raised by Kellerman.

In August 2013, the FDA required new, more stringent warnings about the peripheral neuropathy risk with Avelox, Levaquin, Cipro and other fluoroquinolone antibiotics, indicating problems may last for months or years after an individual stops taking the drug.

The new label announced by the FDA required the drug makers to warn patients that if they experience symptoms of peripheral neuropathy, they should contact their doctors and be switched to another antibiotic from a different class of drugs.

Avelox Risks Withheld

Fluoroquinolones are among the most widely used antibiotics in the United States, with about 23.1 million patients receiving prescriptions for an oral version of the antibiotics in 2011. Since it was introduced in 1999, Avelox has increased in popularity within the class, approaching blockbuster drug status.

Kellerman alleges that Bayer and Merck knew or should have known about the Avelox peripheral neuropathy risk for years, indicating that studies have linked fluoroquinolones to a risk of permanent nerve damage for years before the medication was even introduced.

A study published last month in the medical journal Neuorology suggested that users of oral fluoroquinolones may face double the risk of developing peripheral neuropathy. Researchers found that current users of Avelox and other similar antibiotics faced an 83% increased risk of suffering nerve damage, and new users faced more than double the risk of peripheral neuropathy compared to those not taking the drugs.

“Defendants failed to appropriately and adequately inform and warn Plaintiff and Plaintiff’s prescribing physicians of the serious and dangerous risks associated with the use of Avelox concerning peripheral neuropathy, as well as other severe and personal injuries, which are permanent and/or long-lasting in nature, cause significant physical pain and mental anguish, diminished enjoyment of life, and the need for medical treatment, monitoring and/or medications,” according to Kellerman’s complaint.

The Avelox lawsuit pursues claims for strict liability, failure to warn, negligence, breach of warranty, fraud, negligent misrepresentation and fraudulent concealment. It comes amid a growing number of similar Levaquin lawsuits and Cipro lawsuits being pursued on behalf of former users of those related antibiotics, which have also been linked to a risk of peripheral neuropathy.
