|
- Due to the risk of CRS and neurologic problems, you should be hospitalized for 48 hours after all doses of TALVEY® that are part of the “step-up dosing schedule.” The “step-up dosing schedule” is when you receive the first 2 or 3 doses of TALVEY®, which are smaller “step-up” doses, and also the first full “treatment dose” of TALVEY®.
- TALVEY® is given weekly or every 2 weeks. Your healthcare provider will decide the number of days to wait between your doses of TALVEY® as well as how many treatments you will receive.
- If you receive TALVEY® weekly, “Step-up dose 1” is given on day 1 of treatment. “Step-up dose 2” is usually given on day 4 of treatment. The first “treatment dose” is usually given on day 7 of treatment.
- If you receive TALVEY® every 2 weeks, “Step-up dose 1” is given on day 1 of treatment. “Step-up dose 2” is usually given on day 4 of treatment. “Step-up dose 3” is usually given on day 7 of treatment. The first “treatment dose” is usually given on day 10 of treatment.
- If your dose of TALVEY® is delayed for any reason, you may need to repeat the “step-up dosing schedule” to receive TALVEY®.
- Before each “step up” dose of TALVEY®, you will receive medicines to help reduce your risk of CRS. Your healthcare provider will decide if you need to receive medicines to help reduce your risk of CRS with future doses.
- Your healthcare provider will monitor you for signs and symptoms of CRS and neurologic problems as well as other side effects, and treat you as needed.
TALVEY® is available only through the TECVAYLI® and TALVEY® Risk Evaluation and Mitigation Strategy (REMS) due to the risk of CRS and neurologic problems.
You will receive a Patient Wallet Card from your healthcare provider. Carry the Patient Wallet Card with you at all times and show it to all of your healthcare providers. The Patient Wallet Card lists signs and symptoms of CRS and neurologic problems.
