It takes many many years or a catastrophic event (like happened in Japan with clioquinol) to identify a drug as a cause of PN.
When drugs are still on patent, often this information is suppressed by the companies themselves.
I think ALL drugs are capable of causing negative reactions in some people. It depends on how well they metabolize the drug and their own particular genetic chemistries.
There are forms available at the FDA... Medwatch where you can report this. Also at Patientsville.com
