Pharmacy/Metronidazole and nerve damage?


What is the likelihood of metronidazole causing Peripheral Neuropathy or nerve damage?


The UK clinical data does not define any frequency for peripheral neuropathy, but in so doing it can be assumed that the frequency is probably less than "very rare" - defined as less than 1 in 10,000 patients.

Where neuropathy has occurred, it has usually reversed on completion of the course or discontinuation of the drug.

If you have only been prescribed metronidazole for a short period, I would suggest that treating the underlying infection is more important than a potentially very small risk of difficulties.

I hope this helps.

I am happy to answer general questions on medicines and hospital care. If possible, please use approved / chemical names rather than brands which are not internationally recognised. Like all health professionals I am bound by a duty of care which prevents me giving detailed information about medication or treatment of people other than the questioner. I will endeavour to help wherever possible or point towards more appropriate advice. If however your question crosses too far into patient confidentiality, I hope you will understand why I cannot answer your question. Consider.. would you want me to discuss your care with a friend or relative without your knowledge?
