It depends on the Dr, but if in doubt, I would discontinue for a few days: Should metformin be discontinued before doing a hysterosalpingogram (HSG)?
Patients should go off metformin for several days prior to any x-ray procedure in which iodinated compounds will be used, including the hysterosalpingogram where contrast dye is injected into the uterus (note: this is a different procedure than a sonohystogram where saline is injected into the uterus before an ultrasound).
The reason for this recommendation is that the kidneys clear both the dye and metformin. It should not be a problem if renal function judged by creatinine and blood urea nitrogen (BUN) tests is normal. Renal function testing should be performed before metformin is started, and periodic screening is prudent. Many of the users of metformin are older diabetics with altered kidney function, and this is added precaution. http://www.inciid.org/faq.php?cat=in...ty101&id=2#134
