The time usually depends on how many grams are to be infused and whether or or not it is a 5% concentration such as Carrimune or a 10% concentration such as Gamunex. Also the patient’s body weight comes into play. A 200lb person can be infused more quickly than someonee who weighs 125lb. Good luck.
I receive IVIG infusions (Gamunex) every three weeks. They are good for me. Was able to get up and dance with my grandaughters at my grandson’s wedding a few weeks ago. The only thing that is holding me back is my arthritis in the hips and knees. I am still taking Prednisone (15mg) a day. Trying to get off again.
