I don't have any problems - don't take blood thinners or have a special diet. Can't say I have ever heard of this as a side affect of IVIG. Since it is completely out of your system in 3-4 weeks, don't see how it could be a cumulative problem; but, I'm not a doctor so don't take my word for it. I just know I don't have any such problems and I have been doing this for 10 years.

Good luck!
