Win Rho

How does this medicine work?

Win Rho can be given only to Rh-positive persons who have idiopathic thrombocyopenia purpura (ITP), and who have not had their spleen removed. ITP means platelets (cells that help with blood clotting) are destroyed in the body. Win Rho may temporarily increase platelet counts in these patients.

Win Rho is a human plasma product that has been specially treated to remove viruses.

Win Rho usually begins to work in 1 to 2 days, with a peak effect in 7 to 14 days. It lasts an average of 1 to 3 weeks and has been effective for up to 5 months. Repeat doses may be needed.

How is it given?

Win Rho is given into a vein (IV) in the hospital or clinic.

What are the side effects?

Win Rho has fewer side effects than other ITP treatments, steroids or gammaglobulin.
