SOLIRIS® (eculizumab) works by blocking a part of the immune system called the "complement" system. By blocking complement, SOLIRIS reduces the destruction of red blood cells (hemolysis) and therefore improves the symptoms of PNH.
In clinical studies, SOLIRIS blocked hemolysis in every PNH patient and all patients sustained a reduction in hemolysis for the entire time they were taking SOLIRIS, ranging from 10 to 54 months.
Since PNH is a chronic disease, SOLIRIS is intended to be an ongoing therapy. Patients who start SOLIRIS should continue to take it even if they feel better. If for some reason you and your doctor determine that you should stop SOLIRIS therapy, only your doctor can safely manage taking you off the drug.
Because SOLIRIS blocks part of the immune system, you may be at an increased risk for certain infections during SOLIRIS treatment. Your doctor will give you important safety information about SOLIRIS. You will need to have all recommended immunizations and vaccines before you start treatment with SOLIRIS.
