In February, 1998, Bristol-Myers Squibb announced revised labeling for the
use of Glucophage in patients requiring radiologic studies involving
intravascular administration of iodinated contrast materials. (That is, in
situations where a person on Glucophage will need X-rays using an injection
of "dye" to help get better-appearing X-ray results, such as studies of
blood vessels and the interior of the heart.)
Revised labeling for use when radiologic studies are planned "is based on
the experience of leading radiologists, the short half-life of Glucophage (6
hours), and its relatively rapid clearance by the kidneys. The labeling now
recommends that:
a.. Glucophage should be stopped at the time of or prior to the procedure.
b.. Glucophage should then be withheld for 48 hours after the procedure.
Once renal function is found to be normal, Glucophage therapy can be started
again."
(Per Feburary 1998 letter from BMS.)

Thnks for the note. So far as I know at this point, contrast materials are
not implied.
