...hi ... well this was my only new prescription, other 2 had been on for ten years... and there were 3 pages of warnings etc. about side effects, not to take over age of 65 etc., but have had conversations with pharmacists before to almost disregard these pages, their saying its just for insurance purposes; however checking the internet which I ought to have done before taking the pills, I dont think I would have taken them; in fact two quinolone drugs I believe were successfully sued in USA Courts - dont have info at my fingertips now. Things is side effects with these do not always show up whlile taking the quinolone drugs! As in my case about 2 weeks later and can be up to MONTHS later... its on Internet.
As well as P.N. an often-had side effect is tendon snapping back of leg and runners or just walking up stairs etc., they forget that 2 months or more ago they took a quinolone drug. If you read the book Poison Pills a man's wife was terribly stricken after ONE pill, similar to the 14 I took....I firmly believe my P.N. was caused by Norflox (Canada), a quinolone black box drug with all the warnings... for a mere UTI... also that they should only be used when almost life or death infection when a severe reaction may be better than death type thing.JMO

p.s. Just a fast check Health Canada back in 2017:
"Information for consumers

Fluoroquinolones are a class of prescription antibacterial drugs that are used to treat several types of bacterial infections.

Fluoroquinolones are generally well tolerated but they have been associated with rare serious side effects that were disabling and persistent, including tendon damage, nerve damage in the hands and feet, and central nervous system disorders.
***These side effects can occur hours to weeks after exposure to fluoroquinolone treatment."
