I'm having a hard time sourcing preservative-free lidocaine. Do you think lidocaine with preservative is safe to use for joints, RFA, etc?

I don't typically inject local for epidurals, but do use PF if I have an acute radic.

Thanks

The same reason we have to throw away a big bottle of contrast after using 2cc.. it makes the companies more money. I mean it’s an infection risk.. sorry
 
I was taught (and I was trained in a fairly conservative fellowship) that it had to with the infection risk from inserting multiple needles into the same vial numerous times.

But I’m happy to hear you guys are using multi dose vials. It would save quite a bit of money as a 1cc vial of depo 40mg is close to $10 each around my neck of the woods
