There are no tests for this yet. Doctors tend to not admit this damage, as they are afraid of being blamed and sued.

And there is another nasty thing that may happen after these drugs as well. The DNA damage they do to cells can affect tendons and in some people tendons may be weakened and rupture. This typically happens months after the last dose, as it takes time to manifest. The knee tendons and achilles are the prime target. But we have had two men on NT who ruptured their bicep tendons months after fluoroquinolones.

These drugs damage DNA and affect the mitochondria in cells. The nerve cells are very sensitive and are damaged quickly.

Come to our PN forum and search "fluoroquinolones" for more
posts. We have several now and some in the past who had this.
JesseM is posting about it now in fact. His doctor in Chicago diagnosed him (and that is pretty rare).

Jesse's doctors did not recommend anything for him other than symptom relief. Most doctors have not investigated this problem at all. Dr. Jay Cohen MD has a website discussing it:

You might find that supplements supporting mitochondrial functions may help you heal.
These are:
CoQ-10
acetyl carnitine
magnesium
NAC

This is more common than most people realize. These drugs were initially designed to be 3rd or 4th line options when others fail.
But Big Pharma pushed them aggressively on doctors who now prescribe them 1st line. The tendon ruptures were discovered in DOCTORS themselves first who used the Cipro samples heavily.
They started rupturing tendons, so that link to the toxicity was revealed in them first. One would think there is a lesson in that, but I guess not?
