Hi All, Well it has been 23 days since I was released from the Hospital after my 5 day loading dose of IVIG. the treatment worked well for me with very little side effects other than headache. I still take 60 mg of Mestinon every 3 hours and 40 mg of Prednisone daily and I have been able to return to work part time. Two days ago I began with a sore throat and now have a horrible cough and My MG symptoms are the way they were before my IVIG. I am beginning to feel the weakness returning including vision issues. I am not sure if the effectivness of my IVIG stopped or if the virus just caused me to feel weaker? Does IVIG make you more open to infection? I work as a counselor in a very rural area with individuals that do not have great access to medical care?
