TECVAYLI REMS — required
Closed distribution. All four parties must be certified/enrolled before any dispense or administration:
- Prescriber training + REMS enrollment
- Healthcare facility certified (CRS/ICANS recognition + tocilizumab on hand)
- Pharmacy verifies prescriber + facility cert before dispensing
- Patient enrolled + counseled + carries wallet card
- Web: tecvaylirems.com
Common error: dispensing or administering without verifying all four certifications. Triggers FDA reporting + claim denial + payer recoupment.
