What happens if you miss a dose of Afamitresgene Autoleucel Injection?
Last updated September 7, 2026.
**Afamitresgene autoleucel (Tecelra) is given as a single one-time infusion, so there is no repeat dose for you to miss.** You do not take this medicine at home, and there is no catch-up dose to make up. What can be missed is an appointment in the treatment sequence: the visit where your T cells are collected, the lymphodepleting chemotherapy given in the days before infusion, the infusion itself, or the follow-up monitoring visits afterward. These steps are timed to work together, so a delay in one usually shifts the others. If illness, transportation, or anything else keeps you from an appointment, call your treatment center the same day so your team can rebuild the schedule. Keep the center's phone number saved in your phone and bring a written copy of your appointment dates to every visit.
What to do
- Call the center first: If you cannot make any scheduled visit, call your treatment center the same day rather than waiting for the next appointment.
- Do not skip the chemotherapy days: The lymphodepleting chemotherapy given before the infusion is part of the treatment, and missing it can change when the infusion happens.
- Keep the follow-up visits: Monitoring after the infusion checks for fever, low blood counts, confusion, and other effects that need fast treatment.
- Stay close by: Plan to remain near the treatment center for the period your team sets after the infusion, and have someone who can drive you.
- Track the plan in writing: Ask for the dates of cell collection, chemotherapy, infusion, and follow-up on one sheet so nothing gets lost between visits.
- Get help fast: Fever, chills, trouble breathing, severe fatigue, or new confusion after the infusion need same-day medical care, not a wait-and-see approach.
