A family member of mine ended up with permanent peripheral neuropathy in their feet within days from taking a fluoroquinolone-class antibotic for something that wasn't even that serious. They were old enough that remyelination wouldn't occur, and it didn't. Still can't feel their feet to this day, and it happened a decade ago. Funny enough I was prescribed a fluoroquinolone a few months back without even asking; the condition was so benign that using it was left up to me as optional. The risk calculus there was unfathomably bad, and suffice it to say I didn't take any.
