Soliris

Generic name: Eculizumab
Drug class: Selective immunosuppressants

Usage of Soliris

Soliris is a monoclonal antibody. Eculizumab binds to proteins in the blood that can destroy red blood cells in people with genetic conditions that affect the natural defenses of red blood cells.

Soliris is used to prevent the breakdown of red blood cells in adults with paroxysmal nocturnal hemoglobinuria (PNH).

Soliris is also used to treat a rare chronic blood disease called atypical hemolytic uremic syndrome (aHUS) in adults and children who weigh at least 11 pounds (5 kilograms).

Soliris is also used to treat myasthenia gravis in adults.

Soliris is also used to treat neuromyelitis optica spectrum disorder (NMOSD) in adults.

Soliris is available only under a special program. You must be registered in the program and understand the risks and benefits of this medicine.
