I have read some things (here and elsewhere) about the potential for PN if you have taken fluoroquinolone antibiotics.

I took a course of Levaquin approximately 7 years ago, for a case of bronchitis that didn't respond to a few other antibiotics.

The bronchitis was causing coughing fits that lead to laryngospasms - (if you want to feel like you are about to die, try experiencing one of those). I would have taken anything they gave me at that point in time.

Anyway, I was just curious whether or not there is any evidence that PN caused by taking fluoroquinolones can occur many years later. Or, is it a more immediate effect?

The damage from fluoroquinolones is insidious...and it may add onto other damage from other environmental triggers that affect DNA of mitochondria. There are over 100 causes of neuropathy.
And some people may have additive situations of damage... some of this, and some of that...etc.

I haven't seen exact time frames given, yet. But each person is different. It seems to me that PN tends to be concealed for a while, until a certain plateau is reached and then symptoms become noticeable. There is evidence in the CMT community that Levaquin can trigger an asymptomatic (no symptoms yet) CMT adult into a deterioration. Given the highly variable presentations of CMT in those patients who inherit it, one has to
consider environmental triggers that may be in play for all these various individuals.

PN is very complicated, and involves so many factors, that no one clear answer appears to be accessible about it. Some of the posters who come here have immediate reactions to fluoroquinolones, and others have delayed reactions.

Yeah, this is kind of what I figured. A person is exposed to so many things during a lifetime. Usually, you assume that brief low level exposures to toxic materials doesn't cause major damage. (You don't have any immediate symptoms of a problem, so you assume everything is fine.)

But the additive effect is hard to predict. It seems like every time I do a bit of reading, I find about 5 more things that could be causing me a problem. But no way to know which ones (if any) actually are causing me a problem.

So, I'll just continue to work towards healthy living, a healthy diet, and a range of supplements to support good circulation, healthy nerves, and mitochondrial support.

I'd not accept any further fluoroquinolones if possible. There is always a chance of a life threatening situation, where you may not have much choice.

But for UTIs there are drugs that work that are not so nerve damaging.

Have seen Dr. Gareth Parry (not as a patient) a number of times. No question that some drugs are not for a CMTer. The drugs can make it worse. Or they can cause evident symptoms in some people who have CMT but are yet unaware of it. That is why there is a neurotoxic medications list for a person with CMT.

Do you have a link to this neurotoxic medications list? (Seems like something that anyone with neuropathy would want to have as a reference - not just those with CMT)

The list is for medications that are potentially toxic to CMTers. Some of them more than others. CMT affects the peripheral nervous system (PNS). CMT is one of the most common "inherited" neurological disorders.

I understand. I just thought if a drug was neurotoxic to someone with CMT, it might not be very good for other people either - especially if you have some form of PN.
