I was started on the mestinon syrup in the hospital 3 weeks ago and had an IVIG infusion. The syrup is so much better for me to use. I have been set up for monthly IVIG infusions for 6 months (starting next week) until cellcept kicks in more. Been three weeks since my last infusion the 40mg q 6 hrs of mestinon is too much now and i need to lower it. It's great to be out of bed more and doing things around the house after 3 months of being in bed.
