About Chronic Immune Thrombocytopenia (ITP)
In patients with ITP, the immune system attacks and destroys the body's own blood platelets, which play an active role in blood clotting and healing. Common symptoms of ITP are excessive bruising and bleeding.3 People suffering with chronic ITP may live with an increased risk of severe bleeding events that can result in serious medical complications or even death.4
