Sylvant 400mg Inj (Siltuximab) for Multicentric Castleman's Disease: My Experience and Questions
I was diagnosed with Multicentric Castleman's Disease (MCD) and started treatment with Sylvant 400mg Inj (Siltuximab) a few months ago. The medication is given intravenously and works by blocking IL-6, which has significantly reduced my symptoms. However, I'm curious about others' experiences with this treatment, especially regarding side effects and long-term management. The potential side effects list is extensive, and while I haven't experienced any severe reactions yet, I'm always on guard. What has your journey with Sylvant been like?
