Besremi

Besremi is a medicine used to treat polycythaemia vera in adults who do not have symptoms of an enlarged spleen. In patients with polycythaemia vera, the body produces too many red blood cells, which can cause the blood to thicken and reduce blood flow to the organs. The patients’ spleen may also become larger as it tries to remove excess cells. Polycythaemia vera is rare, and Besremi was designated an ‘orphan medicine’ (a medicine used in rare diseases) on 9 December 2011. Besremi contains the active substance ropeginterferon alfa-2b.
