What is the life expectancy of someone with Fluoroquinolone Toxicity?

Varies.

Also did you take an Fq with another medication that it should not have been taken with?

There are some who took just one Fq pill and enddd in a wheelchair or dead. Then there are some who are 20 year Floxies and some bed ridden. Every reacts differently. Then there are some who took an Fq several times over several years not knowing that have been affected yet or they had a delayed and then whamo ... their in a wheelchair or dead, and most Fq victims with delayed reactions never connect the dots that their illness and diease(s) was from the Fq they took 7 months earlier or 10 years later. Very complex. I recommend you join the many Floxie Facebook groups based mostly in the USA, Canada, uk, Germany ...
