Fostamatinib, sold under the brand names Tavalisse and Tavlesse, is a medication used to treat chronic immune thrombocytopenia (ITP). It is used in cases were other medications have not worked. It is taken by mouth.

Common side effects include diarrhea, high blood pressure, nausea, respiratory infection, dizziness, liver problems, rash, abdominal pain, tiredness, chest pain, and low white blood cells. Use in pregnancy may harm the baby. It is a tyrosine kinase inhibitor which blocks the enzyme spleen tyrosine kinase (SYK). This reduces the immune system's destruction of platelets.

Fostamatinib was approved for medical use in the United States in 2018 and in Europe in 2020. In the United Kingdom a dose of 150 mg twice per day costs about £4,600 per month as of 2021. This amount in the United States costs about 13,000 USD.
