Brennan, I did more research on the iodine/shellfish thing. I guess they have changed their tune in the past few years! I did research a long time ago and "everyone," including Mayo, had been saying don't have Iodine if you have a shellfish allergy. Well, I guess now they've backed off of that stance. Every single time and on every single "form" before a CT, they ask if someone has an allergy to shellfish. Unreal. It always makes me question if this is health driven or drug company driven.

It hardly matters what studies say when you DO react to a drug so strongly. You should never have that drug again.

And a very detailed article from the UK.

Absolutely Annie. If you have any kind of negative reaction to the contrast dye you should never have it again - the next time may be worse again. I don't react badly to it myself but I do know that many people do.

The link I provided indicated that people with asthma seem to be likely to have a problem (the flood of histamine probably?) I'd expect that this is the same reason MGers tend to have troubles with it.

Guess I picked the wrong day to read this topic as my first CT Scan was just scheduled for Monday

Made it through the CT scan fine with no reactions but a day later I am feeling really weak especially in my hands. Has anyone experienced a delayed reaction like this to the dye. I was feeling real good last night and was thinking I may be turning a small corner. Today I have to say I am a bit discouraged.

Any kind of stress will cause an increase in MG symptoms. The dye reaction that I experienced was immediate. It occurred within 8 seconds of injection.
