Yup heard of it!!

Hi ya Alice,
Yes it is classed as a biphosphanate, which as you mentioned is to counter the nasties of long term steriod use. I have been on etidronate for a while now, for a 2 week period every three months. There are a few things to consider if taking biphosphanates ie denstist work including extractions of wisdom teeth etc as it alters the bone/cavity healing process.
Am glad to hear your neuro is taking steps to help reduce possible longterm side effects for you. Hope you still doing well, will continue to watch your progress in your postings.
all the best
