Sylvant
treats a rare disease called Multicentric Castleman's disease (MCD). Tell your doctor if you have an infection as you shouldn't receive Sylvant if you have a severe infection.
Sylvant Overview
Sylvant is a prescription medication used to treat a rare disease of lymph nodes and related tissues called multicentric Castleman's disease (MCD). While not officially a cancer, MCD acts similarly to Lymphoma, a cancer of the lymph nodes. MCD causes an abnormal overgrowth of immune cells in lymph nodes and related tissues in the body.
Sylvant is an injection that works by blocking a protein that stimulates abnormal growth of immune cells.
Common side effects include itchy skin (pruritis), weight gain, rash, increased levels of uric acid in the blood and upper respiratory tract infection.
