TAVALISSE is a drug used to treat adults with low platelet count due to chronic immune thrombocytopenia (ITP) when a prior treatment for ITP has not worked well enough. Chronic immune thrombocytopenia is an autoimmune bleeding disorder. In patients with ITP, the blood doesn't clot as it should because of a low platelet count.
TAVALISSE is a tablet that is taken twice daily. After 4 weeks, the dosage can be increased as necessary, to reduce the risk of bleeding.
