You may have read on the NCCAM website or on Wikipedia that ''silver may interfere with the absorption of some antibiotics (thereby reducing their effectiveness.).

This claim has intrigued me for some time so I have tried to follow it up. Googling produced no answers. Neither did searching the PubMed website. So I emailed the NCCAM and requested a reference for the claim. They emailed back and said it comes from the this FDA safety alert...

The FDA Safety Alert contains no reference for the claim either, so I next emailed the FDA and asked them for a reference.

Their response was "Please contact the FOI staff at (301) 796-3900 to determine whether the records you are seeking are maintained in the Public Reading Room, Electronic Reading Room, or if the information requires the submission of a FOI request."

Thats as far as I have gotten so far but interestingly Steve Barwick has pursued the same enquiry with the same response. He claims to have filed an FOI request and is awaiting an answer.

Regardless, it seems remarkably hard to a find refererence for this quite extraodinary and oft repeated claim.

Normally I wouldnt trust a word that Stave Barwick writes but in this case he produces what I think is quite a reasonable and informative article that corresponds closely with my own experience. You may find it interesting...
