Q. I was prescribed the generic antibiotic Levaquin (levofloxacin) on 6/25/13 for “walking pneumonia.” The doctor did not provide any information about the drug. The prescription was for one a day for 10 days.

After two days (2 pills) I was in such extreme pain throughout my entire body that I could not walk, get up or go down stairs. I was in a wheelchair for a week and had to use a walker for a couple of weeks more. The pain in my joints, especially my neck, upper shoulders, lower back, legs, knees, etc. was almost unbearable.

It has now been almost eight months and I am still experiencing joint pains that seem to move around my body: one day my neck hurts; another day it’s my knees, thighs, hamstrings; then my back is affected.

When the pains began, I tried to contact the doctor. I left messages with her office that I could not tolerate the Levaquin and to please give me something else.  She apparently was calling the wrong number, (the office had both my numbers!) and never spoke to me.  Finally, after taking 6 of the pills, I decided to stop as I figured I’d be dead with 4 more!

Upon returning to the doctor a week after my first visit, I told her of my experience and that I had stopped taking the antibiotic.  She insisted my side effect reactions had nothing to do with the Levaquin and were not a result of this drug!  She told me to take 800mg of ibuprofen three times a day for the pain.

A month later in July I saw my orthopedist.  He could offer no help, but his nurse shared with me that she had had the same side effects from Levaquin and that it had been a year and she was still experiencing joint pains all over; one day here, another day there.

Going on the Internet I discovered that many other people have suffered the same side effects as I had…some for years!  I called the FDA to report the above, but was not able to get any of the required information from the pharmacy (no manufacturer, expiration date, Lot.#, etc.). I completed 5 pages of information on the FDA’s MedWatch form about side effects and such and faxed them to the FDA.  I also discovered there are some 3400 lawsuits regarding levofloxacin.

A. You are not the first person to report serious complications from levofloxacin (Levaquin). This is an antibiotic in the class called fluoroquinolones (FQs) or quinolones for short. Other medications include ciprofloxacin (Cipro), levofloxacin (Levaquin) and moxifloxacin (Avelox).

You are also correct that it is hard to complete the FDA’s MedWatch forms because it is almost impossible to get the essential information they demand (manufacturer, expiration date, Lot # and NDC number).

Here are some other somewhat similar experiences posted to our website:

“I was taking a 30-day prescription of Cipro for a prostate infection. After playing full court basketball, I awoke the next morning to knees that felt as though they were encased in concrete.

“My legs constantly ache as if I had just walked 20 miles.  Many nights I cannot sleep due to the pain in my legs and, for now, I cannot play basketball as the left knee area, in particular, is too weak.

“Ever since that time (20 months ago) I have suffered in every way imaginable. Sometimes I cannot even walk up my apartment stairs. I have seen my doctor, an acupuncturist and chiropractors. No one can make it go away. This has totally impacted my life, since I can’t play tennis and have a very hard time playing basketball. Do you have a suggestion?” Doug

“I took this medicine four years ago. I was also very physically active before taking it. After 7 days on the med, I developed body-wide tendon and nerve damage that has yet to improve. There are literally thousands of people who have been crippled.” Greg

“I had a similar experience with Cipro. I took it a year and a half ago and have had terrible joint problems ever since. The problems started almost immediately after taking Cipro. I’ve had to spend thousands on tests, physical therapy and doctors’ visits. The worst is my feet and ankles hurt so bad that walking is difficult now. I can no longer exercise without suffering days of pain. All this time, there is some improvement but much of the damage is permanent.” D.B.

“I took Levaquin on Nov.14, 2012. After 6 pills I had Achilles tendonitis, small tears, muscle aches and joint pain all over. Two years later I am still suffering from tendonitis, bursitis in my shoulder joints, fatigue and insomnia. I never ached so much in my life and it continues to get worse. I walk with a cane. There is numbness in my foot and leg diagnosed as neuropathy. Levaquin was prescribed for suspected urinary tract infection. It was contraindicated with my other meds and my age. This just should not be.

“This drug has caused permanent damage and ended most of my life activities. Doctors need to be informed what this med does and care about the consequences. I hope this antibiotic gets off the market or is used only in a life or death situation.” L.P.

We could provide dozens of other stories, but by now you have the idea. According to the Food and Drug Administration, more than 21 million people get a prescription for a quinolone antibiotic each year. Such drugs are prescribed for sinusitis, urinary tract infections, bronchitis, pneumonia, prostatitis and skin infections. Cipro has been around for decades.

The FDA issued an alert about FQs last year about neuropathy:

“This serious nerve damage potentially caused by fluoroquinolones may occur soon after these drugs are taken and may be permanent… Peripheral neuropathy is a nerve disorder occurring in the arms or legs. Symptoms include pain, burning, tingling, numbness, weakness, or a change in sensation to light touch, pain or temperature, or the sense of body position. It can occur at any time during treatment with fluoroquinolones and can last for months to years after the drug is stopped or be permanent. Patients using fluoroquinolones who develop any symptoms of peripheral neuropathy should tell their health care professionals right away.”

In addition to the nerve damage, these drugs can cause lots of other serious complications, including tendinitis or even tendon rupture. When this happens it can be a life-altering event. Joint pain and arthritis-like adverse reactions are not generally recognized as a complication of quinolones in adults, though they have been noted in children. We tend to believe the people who have reported this problem on our website rather than the official prescribing information for these antibiotics. It has taken the FDA decades to acknowledge the problems with tendons and nerves, so we would not be surprised if it takes years more for the agency to recognize the joint complications.

Unlike many of the people who have reported problems on this website, we are not calling for the banning of quinolone antibiotics. Goodness knows, we are running out of effective medications against serious infections given the degree of bacterial resistance that has evolved over the years. But doctors must inform patients of potential side effects BEFORE people start taking such drugs. Here is a list to be aware of:

Fluoroquinolone Side Effects and Complications:

  • Digestive distress, nausea, diarrhea, constipation, stomach pain, heartburn, vomiting
  • Headache, dizziness
  • Agitation, anxiety, irritability, restlessness, confusion
  • Insomnia
  • Tendon problems, tendinitis, tendon rupture
  • Retinal detachment
  • Nerve damage, peripheral neuropathy, nerve tingling, numbness
  • Allergic reactions, skin rash, anaphylaxis (life-threatening reaction requiring immediate medical attention!)
  • Super-infections including C. diff diarrhea
  • Hallucinations, psychosis, seizures
  • Depression, suicidal thoughts or actions
  • Irregular heart rhythms, torsades de pointes, QT prolongation
  • Kidney or liver damage
  • Blood disorders
  • Arthritis, muscle pain, weakness

    I took levaquin for ten days for diverticulitis. I began having muscle and joint pain and dizziness. Fortunately the muscle and joint pain has mostly gone but the dizziness has gotten much worse and I am now in my seventh week. I am mostly chained to my house. Can’t drive. I have had six sessions of physical therapy with little success. Have others experienced this?

    I was given Levaquin in 2012 for a sinus infection. After 5 days of an 8 day regime I developed bilateral Achilles tendonitis. I was told by the same doctor that prescribed it that the infection could have been treated with a Neti Pot.

    As of approximately 2 months ago I developed peripheral neuropathy in my feet and legs. I now have pain in my knees, and other joints. Until I took this medication people referred to me as a ‘work horse.’ Seldom sick. Active. Sturdy. Strong. There has been a downward spiral of mysterious neural pain. The neuropathy is now causing jabbing pains in my hands and feet. The drug doesn’t affect everyone adversely, but in my case and others, there were clear contraindications.

    I spoke to a casual acquaintance recently, and she was being treated with this medication for a similar ‘non-life-threatening’ sinus infection. Her doctor, like mine, did not discuss the potential side effects. I have been told by 2 doctors that exercise beyond short walks will trigger the neuropathy. Their words. My experience. My experience has been that there is no recourse. Doctors continue to prescribe this medication. Supposedly the ‘black box label’ is sufficient warning. It is not. Until doctors stop prescribing it for non-life-threatening conditions, it will continue to injure people in unbelievable ways and, as for myself, possibly alter the course of their lives. Thank you for opportunity to share.

    I went to the doctor and was prescribed Levaquin for what they thought was pneumonia. I took it for 8 days but after 2 doses I started having pain in my knees and my left upper arm. It got progressively worse and by the 8th day, I could barely walk and getting up and down in a chair was almost more than I could bare. The doctor didn’t want to believe that it could be the Levaquin even though he said it was a rare side effect. I then asked, what could it be then, because I haven’t done anything to myself to cause this. I went back in to see him, he ran some tests and my labwork came back elevated for inflammation. I had already stopped taking the medication, obviously, and he put me on a steroid. It took a few days but I finally started to feel better. Now that my course of steroids is done, the pain is back. And every day it’s getting worse….just like before. I was told that the half life for Levaquin was a week, well it’s been 9 days since I’ve stopped the Levaquin and the pain is back. So is this going to continue? What are we supposed to do? If it gets to the point it did when I was taking the antibiotic….I won’t be able to function. This is a nightmare.

    Prescribed 10 day regimen of Levaquin October 2010 for pneumonia. Seven days into the 10 day treatment, experienced sever tendonitis lower left leg. Over period of 6 months, the pain moved from left calf to left thigh, then to right calf, right thigh, then moved on to arms.

    Five years later, I still have side effects- muscle weakness, leg cramps. It’s permanent damage. I can cope but have very weak legs. After a year of personal training, my legs are stronger, but the side effects still resurface on occasion. This drug should be removed from the market. Or…. at least it should be used as a last resort only for critical needs.

    I was given levafloxin for a uninary track infection it raise my blood pressure so high they said I had stroke I think it was nerve damage cause by a server reaction to the levafloxin

  6. Paul

    I was on Levaquin for 9 days ( I stopped taking the medication) and was having significant difficulty urinating….I had a urine test which was negative, no pain, no burning and my prostate was not enlarged. After doing research, I realized that the Levaquin can cause urinary problems….how long will it take to get back to normal? I stopped two days ago, still having the same issue.
