Anybody with P Anca vasculitis being treated with retuximab infusion ?

Any thoughts on having rituximab infusion versus Cellcept daily for treatment of P Anca vasculitis? I was stricken in 2020 with seizure and vision loss after Anca inflamed my dura and eye. I was dosed heavily for months with prednisone then started in Cellcept after insurance would not cover rituximab… stayed on Cellcept but I got squamous cancer…they took me off and said we would monitor thru MRI. and blood work.. well no2023 and I have had a big flare up and it attacked my eye again resulting in bad dipole.. 7 plus weeks of bug Prednisone and then hopefully the rituximab infusion..any experience with this drug and effects would be appreciated. Thank you
