@wendyw - My assumption with Pfizer is that they would not admit to you a connection between kidney stones and Effexor unless it is in the detailed information sheet that comes with the prescription. Either they don't know, are investigating the possible connection themselves, or another option but for fear of a law suit they will probably not admit something like that to you unless it is in the detailed information sheet that comes from Pfizer with the script. I mean the paper with the impossible to read tiny writing and not the paper from the pharmacy, although reviewing the latter would be a good idea too.

@wendyw - Is there a reason why he has had 3 nephrologists? Getting second opinions can be good but jumping around too much can be detrimental so I'm wondering if you have found one you are satisfied with or are you still searching?

It actually took this to find a good one who could communicate.

@wendyw - well I'm glad you finally found someone you like. Having confidence in your doctor is so important!
