Grady’s Story – Levofloxacin Toxicity and Recovery

Grady tells his story about fluoroquinolone toxicity, and what has helped him, in this video –

This is a summary of what Grady states in the video:

Grady was initially floxed by Levaquin/levofloxacin in 2005. He suffered from extreme weakness, rhabdomyolysis, pain, anxiety, insomnia, extreme pain and weakness in all his muscles and tendons, and an inability to move. He was bedridden for two full years. After two years in bed, he was able to start to move again, but he still suffered from constant chronic pain and other symptoms. For more than 12 years he was ill. After 12 years of being sick, he found something that helped him – high doses of magnesium. To get doses of magnesium that were as large as what he needed, Grady took both oral magnesium supplements and he also used transdermal magnesium. With his protocol of high doses of magnesium, he was gradually able to recover.

Grady says that he’s able to go out and do things, have a social life, and he’s able to live a somewhat normal life. He’s not back to the level of health that he was before taking levofloxacin, but he is doing much better now than he was for years after getting “floxed” by levofloxacin.


Note from Lisa – I hope that Grady’s story of pain, and eventual improvement, helps to inspire you! I often get messages from people asking about the possibility of recovering and healing after a long-term battle with fluoroquinolone toxicity. A lot of long-term floxies feel discouraged by the lack of recovery stories on this site that they can identify with. I hope that they find inspiration and hope in Grady’s story. Even though he was suffering for a very long time, he found something that helped him, and now he is living a “somewhat normal life.”

    What kind of spray magnesium did you use? They’re so many to choose from on amazon. I get so frustrated and give up. I just cannot seem to concentrate. What other things have you done?

    • mntnhigh4 August 24, 2018 at 10:01 am Reply

      Hi, Laurie.
      I use Life-Flo brand magnesium oil. Other things I’ve found helpful are low dose iron and high dose manganese for energy, along with the herb bacopa for anxiety. I also take a probiotic and vitamins b, c, d and e, and extra amounts of vitamin b12 and p-5-p (active b6)
      I think minerals seem to help me much more than vitamins do.

    Hi Grady,

    Does it all come back if you fail to use the supplements?

    I’m a year floxed and have a strong suspicion that being floxed is completely due to gut dysbiosis. GABA and vitamins are made in the gut for instance.

    Do you have an opinion on this theory? I feel I wasted a lot of time waiting around for improvements because I believed all of the hype around mitochondrial damage.

    Glad happy to hear of your improvement.

      Hmmmm. I wasn’t familiar with gut dysbiosis until seeing your comment. But from my what I’ve read and looking at that, it would make sense that that could be the issue. I have used probiotics. I would need to look at this further, but it does give me a different, interesting direction. The mitochondrial damage does make sense symptomaticly. But so could gut dysbiosis. Thanks for pointing that out.

        Hi Grady,

        Thank you for your video. It has helped me!

        When you stop using magnesium, do your symptoms come back?

    Hello Grady,

    My name is Louis, and I have taken Levofloxacin for a UTI. Thank you for sharing your story and personal advice. I would like to talk to you about my personal story and share some of my problems with you. Can you please reach out to me at

    Thanks again for sharing your story.

    Best wishes,

    Did kratom help you for FQ toxicity?

    • mntnhigh4 September 7, 2018 at 10:12 am Reply

      It did. Tremendously. Both for the pain and the anxiety, along with most other symptoms. I felt very good while taking kratom. I’ve tried opiate pain medications in the past, and they didn’t work as well. There is the physical dependence and uncomfortable withdrawal that comes when you stop using kratom. That’s important to consider. Still, if it was easier to obtain I would have stuck with it. Coupled with the magnesium, I could work while on both, which isn’t the case with magnesium alone.

    Hi Grady,
    my heart goes out to you! What you have gone through is living hell and what you lost is hardly to imagine!

    Wish you all the best for the future and thank you for sharing!

      Thank you so much, Lenny! Things are improving, so there’s always hope! Thank you for watching.

    Hi Grady
    Thank you so much for you story & video. I’m so sorry you have suffered so long. It’s very kind of you to help others who are going through Floroquinolone toxicity. I’m at month 5 now and much improved from when I took Cipro for a UTI in June. I couldn’t walk very well for the 1st few months. My muscles were tight when I tried to walk even the shortest distance. Along with the scary CNS symptoms of despair, depression & horrible anxiety. I found myself crying everyday for months. I hardly recognized the person staring back at me in the mirror. I’m a woman age 53 in what I thought was good health. I’m sorry you list so much of your life. It is very hard for people to understand that a drug, especially an antibiotic can hurt you so much. I find myself getting frustrated trying to explain what has happened to me. No one can get the deep despair you feel when your body doesn’t work right and everything hurts. It’s so nice to have others like yourself who have experienced this. It helps so much. Wishing you good health.

      Sandi how are you doing now?

    • mntnhigh4 March 19, 2019 at 2:37 pm Reply

      I’m sorry you’re suffering from this too, Sandi. It’s truly one of the hardest things you ever go through because it doesn’t just effect you physically, but emotionally as well. And then to not have others believe us and what we’re going through makes it even harder. It can make us feel alone and misunderstood, so it’s nice that we can find others that truly understand. Thanks for watching and commenting.

    To all who are suffering, yes, Grady is right. Magnesium is key. In fact I found canine research years ago that showed dogs had fewer tendon ruptures when give Magnesium pre FQs , during and after. It is stunning that even this simple thing was not conveyed to us. Also, to protect the mitochondria, high dose Ubiquinol may be useful. My first dosing was in 1996 and on thru many years before I knew what was causing it. So many tendon injuries and yes depression and suicide thoughts. Now I am using a fasting plan to help remove old dead cells and kick start stem cells. I am desperate to claw back as much of my prior mountain climbing life as possible. Happy to say that muscles are returning. Planning to do the Prolon fasting gig forever and keep the Magnesium and Ubiquinol going in. I also use the other vitamins like Grady did. Keep staying the course. For me it has been a super long haul. We are the pioneers that need to keep sharing with all we meet.

      Great points, Jana. Glad you’re improving as well. Can you tell me more about this fasting you’re doing? I do 3 day fasts only drinking water because I felt it could help. But I’d be interested in finding something that i know is a more beneficial form of fasting to restore my body if there’s something different I can be doing.

    Hello, Grady

    Thank you for sharing your story.
    What kind of magnesium supplement did you use? Whenever I take magnesium it gives me diarrhea. Do you have any tips for that?

    Best wishes!

    • Dee January 7, 2019 at 11:38 pm Reply

      Katy, When I first got floxed 18 months ago I took Mag in pill form and got diarrhea. When I switched to Angstrom liquid mag I did not get diarrhea . It enters the bloodstream instead of the stomach. Hope that helps.

    • mntnhigh4 March 19, 2019 at 2:47 pm Reply

      Hi Katy. Thanks for watching. I use KAL brand magnesium glycinate and Life-flo magnesium oil. I have links to both in this new video:

      If I take more than about 600mg of magnesium orally, I will get diarrhea. So what I do is take about 400mg orally using magnesium glycinate at bedtime. And then I use the magnesium oil to get the rest of my magnesium because it absorbs through the skin and bypasses the digestive track. 6 sprays of the oil equals about 100mg. So I spray on about 50 squirts on my legs and stomach and anywhere else that hurts, let it sit for about 30 minutes, and then shower it off. Hope that helps. Dee makes a good point as well.

    Hi Grady did you shake have taccycardia or brain burning

    • mntnhigh4 March 19, 2019 at 2:50 pm Reply

      Hi Eleni. No brain burning, but I did have tachycardia and shaking, along with brain pressure. They are pretty much gone now, either through the supplements or just the time passing and my body healing on its own. I hope you find relief. 🙏

    Thank you for sharing your story! It gave me so much hope. I am about 3 months in and it’s really hard. I got severe insomnia, so there’s never any rest from this. I am a Christian too, so I will be praying for you. Pray for me too!

    • mntnhigh4 July 12, 2019 at 1:54 pm Reply

      I pray some of what’s worked for me helps you and you find relief soon. Just know it does get better. Thank you for the prayers. You’ll be in mine as well.

    Hi Grady
    I’m at around 20 months out, was doing pretty good but having a relapse of symptoms. I’m going to try to do more of the supplements you have suggested. I ate very unhealthy through the holidays and my stomach is really messed up. There must be something to the idea of our gut biome. I pray you are going really well these days Grady. Thanks again for all your helpful insights.
