Reactions to Cipro, Levaquin, and Other Fluoroquinolone Antibiotics
Since the December, 2001, publication
of my article in the Annals of Pharmacotherapy,1
I've received hundreds of e-mails from people suffering from devastating,
long-lasting side effects associated with Cipro, Levaquin, Floxin, and other
fluoroquinolone antibiotics. Most of these people are young and had been healthy
These antibiotics have legitimate uses in treating
infectious diseases, but they are overused for minor conditions such as sinusitis,
prostatitis, and bladder infections. My stance is that Cipro, Levaquin, and
similar antibiotics should be used only when other, safer drugs are ineffective,
or for organisms that are only sensitive to fluoroquinolones.
As I said on National Public Radio in October
2001, I strongly believe that all people placed on these antibiotics should
be warned about infrequent yet serious reactions that may cause joint, muscle,
or tendon pain or rupture, nerve pain (burning, electrical sensations, tingling),
muscle weakness, thinking or memory problems, heart palpitations, rapid heart
rate, gastric problems, skin rash, or many other unusual physical or psychological
symptoms. These reactions can occur quickly and suddenly, and patients should
alert their doctors immediately.
Doctors, for their part, must recognize that these symptoms can lead to severe, long-term pain or dysfunction, and should stop the antibiotics immediately if at all possible. Because adverse reactions may increase in severity and duration with each exposure, patients with these reactions should not receive fluoroquinolones again. I'd hoped that my article would accomplish this, just as it prompted the U.S. Centers for Disease Control to alter their guidelines for treating anthrax. But it hasn't had the same impact on the medical system.
Most people do fine with these antibiotics. For those who don't, the effects can often be minimized with proper warning and prompt response. Unfortunately, few patients were given any warnings. Again, their rights of informed consent are violated.
On the hopeful side, I
have spoken to the FDA about this issue. They are taking a very serious look
at the problem. But although the FDA has already received thousands of reports,
action is slow. And even if the FDA requires new warnings in package inserts
and the PDR, most doctors will never notice them, and because of the unrelenting
influence of the drug industry, most doctors will continue to overprescribe
these drugs when other, safer, cheaper drugs would do.
So you'd better be informed.
Preventing fluoroquinolone reactions is much, much better than trying to treat
them, because there is no known, specific treatment. Below is the information
that I have sent to people seeking help. I don't know if any of these suggestions
is highly effective, but having experienced a severe, long-term disability
myself in the mid-1990s and now having improved considerably, I encourage
people to keep asking questions and trying things. You can also connect with
others enduring similar experiences with fluoroquinolones at the web sites listed at the end of this article.
Information for People with Fluoroquinolone-Related Reactions
I have sent this information to hundreds of people who have contacted me about their reactions following the publication of my paper. I wrote the paper so that people having these types of problems might get accurately diagnosed, because most physicians have no idea how severe some of these fluoroquinolone-related reactions can be.
First, I should explain I am not a neurologist or orthopedist.
I am a researcher and my major area of expertise is medication reactions,
which you can read about in my medical journal articles and my recent book,
Over Dose: The Case Against The Drug Companies
(Tarcher/Putnam, info & reviews at amazon.com). I wrote the article about
fluoroquinolones because of the reports I received and because no one was
paying attention to this serious problem. My knowledge about fluoroquinolones
in particular and antibiotics in general is limited to what is contained in
the article. I have not conducted any new research on fluoroquinolones since
writing my article in the Annals of Pharmacotherapy in December, 2001, so
you need to check the medical literature and others sources for updated information.
Regrettably, there are few doctors who are informed
about fluoroquinolone-related reactions. You might find information about
knowledgeable doctors at some of the fluoroquinolone websites, where people
have posted a lot of useful information.
As far as I know, there are no specific treatments
for the nerve or tendon/joint/muscle problems associated with Cipro, Floxin,
and Levaquin, and other fluoroquinolones. Most of my information is hypothetical
or anecdotal; some of these recommendations may help some people, but not
Medications such as amitriptyline or other tricyclics,
or Neurontin (gabapentin), may be helpful for neuropathic pain (tingling,
burning or electrical sensations) or nerve pain. Muscle spasms, twitching,
tremors, and seizures may be helped with long-acting benzodiazepines such
as clonazepam (Klonopin) or diazepam (Valium). SSRI antidepressants (Zoloft,
Paxil, Effexor, Prozac, etc.) are occasionally helpful for depression. Because
patients' nervous system are sometimes very sensitive, these drugs should
be started at very low doses and increased, if necessary, very gradually.
Magnesium (chelated) in doses of 400-1000
mg/day may be useful for reducing neuropathic pain or muscle spasms in some
people. Doses over the U.S. recommended daily amount of 320 for women and
400 for men should always be taken with a doctor's supervision. Seniors, people
with kidney disorders, and those taking medications for heart, hypertension,
or other vascular or neurological disorders should have medical supervision
even for RDA doses of magnesium.
Interestingly, another doctor has also been
recommending magnesium, as low doses of milk of magnesia (1 or 2 teaspoons
twice-daily), to be taken for several months. The theory is that because of
the affinity of minerals for these antibiotics, this might help leech some
of the remaining fluoroquinolone molecules from the tissues. Some patients
have benefited, but not all. In discussion with this doctor, our sense is
that calcium, magnesium, and perhaps other minerals may be beneficial. With
magnesium, better absorption is important to get the magnesium into the tissues,
so chelated magnesium or a magnesium solution might work best. As with all
of these recommendations, there's little solid science, so it's trial and
error. (For more information on magnesium, please go to the other magnesium
sections of this website.)
B-vitamins have been reported to reduce tingling.
One person wrote to me that high doses of lecithin have helped with memory
problems. GABA, an amino acid, has some similar qualities to Valium and Klonopin
and may be helpful for anxiety, nervousness, or insomnia.
Anti-inflammatory drugs are controversial: some
people have written to me that they have helped, especially for muscle/joint/tendon
pain; others have written that they have worsened their conditions. If you
have benefited from anti-inflammatory drugs, you might obtain additional benefit
from high doses of omega-3 oils (fish oils; EPA/DHA). There is considerable
literature on this. Omega-3 oils take time to work, but the ultimate result
can be better than standard anti-inflammatory drugs (NSAIDs).
Many alternative doctors are knowledgeable about
magnesium, GABA, omega-3 oils and, perhaps, about other possibilities.
Corticosteroids (cortisone, etc.) are very controversial.
Doctors sometimes prescribe steroids in the hope of reducing the reactions,
but many people have written that steroids actually made their cases worse.
Steroids should be used with great caution unless there is a specific indication.
Fluoroquinolone-linked reactions can be nasty,
and recovery varies from individual to individual, with some reactions resolving
quickly and others lasting years. That's why I do not advocate using fluoroquinolones
as the first antibiotics for treating minor infections. If we are ever to
change the medical-pharmaceutical mindset about this, it will be accomplished
by patients. So please submit a Medwatch report. It's easy to do at: www.fda.gov/medwatch/report/consumer/consumer.htm.
Or call 800-FDA-1088).
I regret that I cannot give you a more specific,
well-proven remedy for these reactions. It is tragic -- and very frustrating
-- that the medical-pharmaceutical system frequently fails to recognize these
problems and, therefore, doesn't warn patients or doctors. So doctors not
only fail to recognize the reactions, but continue to prescribe fluoroquinolones
to people who've already shown signs of toxicity previously. It's a terrible
situation, but not unlike I've seen and written about with other drugs.
I hope that your condition resolves soon. Sincerely, Jay S. Cohen, M.D.
