I have been on Vyvgart for over a year now with great results. Not Hytrulo, but the IV route. Myasthenia gravis was treated with Pyridostigmine, Rituxin, IVIG, Solaris, Pulse dose Steroids and Plasma Exchange with little result. 9 Hospitalizations, 5 in ICU at UofPenn and Philadelphia VA. Lost muscle mass and gained 30 lbs. I was looking into Hospice. I could not walk very far or hold on to things. I started Vyvgart and walked 9000 steps 3 days later. 36 sessions of cardiopulmonary rehab, diet weight loss back to 154 lbs, no hospitalizations. I am 79. Drove one of my cars in time trials this summer after not being able to drive at all for years. Just built a new deck and gazebo at my home. On the other hand another vet I talked to at the VA infusion is having no benefit from it. I was discourged from trying it because of side effects, but I had little to lose. Vyvgart prevents recycling of old antibodies rather than prevention of making new ones. wish you well on your journey. Never give up.
