I received IV iron infusion three times. The first two times doctor ordered the iron to be diluted with a lot of saline solution and given slowly over a three hour period. The third time, which was a week ago, the nurse forgot (in her own words she "forgot" this) the usual dosing and diluted iron in a much smaller amount of saline solution (so the iron was more concentrated). I mentioned this before she started the IV, but she started it anyway, THEN went back and checked my records and came back and asked if I wanted more fluid. Isn't it up to the doctor to decide how much fluid is "necessary?" Anyway, she decided to follow the iron with a medium size bag of saline to match the amount of fluid. After this I developed severe phlebitis and am having neuropathy in the affected arm.
