Hi @moonray A belated welcome to Connect! I just noticed that you’ve been a member for several years but this is your first time dropping by with a comment. Thank you so much for sharing your little trick of Tylenol and water to help prevent headaches with your IVIG infusions.

If you don’t mind sharing a little more about yourself, I might be able to help connect you with other members with a similar diagnosis. What conditon has left you with a weakened immune system?
