1. What TAVLESSE is and what it is used for
What TAVLESSE is
TAVLESSE contains the active substance fostamatinib. It specifically targets an enzyme called spleen tyrosine kinase, that plays an important part in the destruction of platelets. In this way TAVLESSE limits platelet destruction by the immune system and increases platelet count in the body. This helps reduce the risk of severe bleeding.
What TAVLESSE is used for
TAVLESSE is used to treat adults with low platelet counts due to chronic immune thrombocytopenia (ITP) when an earlier treatment for ITP has not worked well enough. ITP is an autoimmune disease, in which the body’s own immune system attacks and destroys platelets in the blood. Platelets are needed to help create clots and stop bleeding.
2. What you need to know before you take TAVLESSE
Do not take TAVLESSE
if you are allergic to fostamatinib or any of the other ingredients in this medicine (listed in section 6).
if you are pregnant.

Tell your doctor, pharmacist or nurse immediately if you get any of the following symptoms while you are taking this medicine:
if you have high blood pressure (hypertension). New or worsening high blood pressure is common in people treated with TAVLESSE and can be severe. Your doctor will check your blood pressure regularly during treatment with this medicine. If needed, your doctor may start you on blood pressure medicine or change your current medicine to treat your blood pressure. Tell your doctor or pharmacist if you get headaches, confusion, dizziness, chest pain or shortness of breath.

Changes in liver function blood tests are common with this medicine. These may be symptoms of liver problems. Liver problems may occur and can be severe. Your doctor will regularly carry out blood tests to check how well your liver is working during treatment with this medicine.
if you get diarrhoea. This is common in people treated with this medicine and can be severe. Tell your doctor or pharmacist if you get diarrhoea during treatment with this medicine.

if you get a high fever (a sign of serious infection), chills, feel sick, or have a general feeling of being unwell. Your doctor will regularly do blood tests to check your white blood cell counts, and you may be told about a decrease in your white blood cell counts (neutropenia).
