When I had mine I got the form with warnings about side effects. When I saw the allergic reaction I was a bit concerned, I asked the tech and was told it wasn't a big deal. Since I was in the basement I didn't have service and I decided to trust them given the large number of my friends who've had MRIs. It was fine, but it seemed like a major thing to toss in the patients lap right before they get strapped down in a tube.

But there’s a potential risk of an allergic reaction to any drug you take, any food or drink you consume, even environmental substances - perfumes; hayfever is an allergic reaction to pollens. You don’t know you have one until you have the reaction. I didn’t know I was allergic to penicillins until I needed them for an infection and it turns out I am.

Good point, I wasn't clear. The warning was about the systemic reaction inside the veins and arteries. Or something along those lines. Whatever it was the warning struck me as much more drastic than the usual allergic reaction warning.
