Over the past few weeks I've noticed decreasing saliva and a dry mouth much worse than the temporary condition I experienced after RAI. Since my meds haven't changed in 4 or 5 months I'm wondering what would be causing this.
It just occurred to me that the contrast used in my scans might be the cause. I've had bi-monthly scans now going on about 6 months so I've had a lot more contrast than at any time in the past.
Can contrast cause this and, if so, does it go away when the scans are reduced or stopped?
