I took Cipro 3 months ago and my peripheral neuropathy began approx 8 days later. since then, i have done a lot of research on fluoroquinolone toxicity, and it seems that these symptoms can show up immediately, as in after one pill, or much later after the drug has been discontinued, as in a year later. also, you can take the drugs prior to having a reaction like that. best to all of you for quick healing.
