Getting your SYLVANT infusion

Before administering SYLVANT® (siltuximab), your doctor will perform blood tests to check that your body is ready to receive treatment. The tests are performed prior to every infusion for the first 12 months, and then every 3 dosing cycles thereafter.

What to expect

SYLVANT is an infusion treatment administered at a hospital, infusion center, or home by a trained healthcare professional.

Treatment with SYLVANT should be continued until disease progression.

When I received my iMCD diagnosis, I was relieved because I knew I was going to receive the proper treatment…and that made me hopeful for the future.
