  1. Ensuring prescribers are educated on the risk of serious bleeding with severe thrombocytopenia and the risk of glomerulonephritis associated with TEGSEDI.
  2. Ensuring prescribers are educated and adhere to the following:
    • Counsel patients on how to recognize and respond to signs and symptoms of serious bleeding and glomerulonephritis.
    • Enroll patients in the TEGSEDI REMS.
    • Submit documentation that periodic monitoring of patients is being done to identify severe thrombocytopenia, serious bleeding with severe thrombocytopenia, and glomerulonephritis.

  3. Ensuring patients are informed on the following:
    • How to recognize and respond to signs and symptoms of serious bleeding and glomerulonephritis.
    • The need to have their platelet count and renal function monitored.

  4. Enrollment of all patients in a registry to further support long-term safety and safe use of TEGSEDI.
