i was a late responder to vyvgart. My first cycle was terrible, i had worsening during the 4 weeks of infusions. I wanted to give up but my neuro convinced me to try a 2nd cycle. Again MG symptoms were worse and much worse than the first cycle. I had already decided to move on to another treatment then 1 month after 4 infusion, i realised i felt better. i thought great, MG is subsiding a bit like it had previously, usually only lasting a week or 2. Each day I kept getting stronger and at some point i could walk without exhaustion. my neuro scheduled another cycle but the gap was about 8 weeks after and for some reason the next infusion cycle also was 8 weeks later. i was feeling great at this point and decided to stay with 4 weeks infusion, 8 weeks off. Eveything has been perfect until my last infusion cycle. first 3 infusions had worsening that lasted a bit longer than usual and with the 4th i have had worsening for 2 weeks. I am still not sure i am fully recovered but i think i am.
