I have been on Vyvgart Hytrulo almost 6 months with mild improvement. I’ve had upper respiratory and sinus infections this winter, but not sure if that is a side effect or just from all the gunk my granddaughters bring to me from daycare. Having issues getting the prescription filled again (a story in itself), so will have missed 2 doses as of tomorrow. Had quite a burst of energy and easier to get up and stand last week, but am tired and weak now, so maybe helping more than I thought. This is kind of a last-ditch attempt for improvement for me. I’m now 64, was diagnosed by Dr. Dyck at Mayo in 2003 as a “dirty CISP” after sural and spinal nerve biopsies in addition to all the other testing after searching for 5 years to figure out why my feet and legs were tingling and going numb and I was having trouble walking. Because of the significant damage done in those 5 years he was not optimistic but not hopeless either. My disease has progressed to a full-blown CIDP diagnosis now. Am now in a wheelchair secondary to a leg fracture and subsequent muscle weakness and wanted to try the Vyvgart to see if I could regain enough proximal strength to get back to using a walker. My neurologist in Missouri was very willing to help me give it a try and the intent is for me to be on it a full year before we make any final decisions about continuing it.
