Taking Privigen

Hi Lauren,
I am taking Privigen. I have been receiving IVIG for six months. I originally had a Loading dose of Carimune and saw results. I then had two more months of Carimune at the Maintenance dosage. There was very little progress. The past three months I have received Privigen at the Load dosage each time. I have been improving. It is my understanding that the change from Caimune to Privigen was due to cost. We have attributed my progress to receiving the loading dose, not the change in the brand of IVIG.
What has been your experience?
