What is TAVLESSE

TAVLESSE contains the active ingredient fostamatinib. It acts specifically on an enzyme called spleen tyrosine kinase, which plays an important role in the destruction of platelets. In this way, TAVLESSE limits the destruction of platelets by the immune system and increases their number in the body. This helps to reduce the risk of severe bleeding.

What is TAVLESSE used for

TAVLESSE is used for the treatment of adults with low platelet counts due to chronic immune thrombocytopenia (ITP) when a previous ITP treatment has not been sufficiently effective. ITP is an autoimmune disease in which the body's own immune system attacks and destroys the platelets in the blood. Platelets are necessary to help create clots and stop bleeding.

Do not take TAVLESSE

• if you are allergic to fostamatinib or any of the other components of this medication (listed in section 6).
• if you are pregnant.
