How many weeks are you admitted for CAR-T?
Most centres admit you a few days before the infusion and keep you as an inpatient for roughly 7 to 14 days afterwards. You then stay within about an hour of the centre for another 2 to 4 weeks. Counting the workup and the manufacturing wait, plan for six to eight weeks away from home.
Discharge is not the end of the stay. This is the single thing families get wrong when they book travel. The inpatient block is only the middle of the period. The centre releases you from the bed long before it releases you from the city, because the reactions this treatment can cause appear quickly and need the same unit that treated you, not the nearest hospital to your home.
Why the first two weeks are guarded so closely. The reprogrammed cells multiply inside the body after infusion. That expansion is how the treatment is meant to work, and it is also what can trigger a severe inflammatory reaction. Most reactions begin within the first week, and nearly all within the first month. The stay is built around that window, not around how you feel on any given day.
Before any of this begins, your own T cells have to be collected and sent for manufacturing — a separate visit, weeks earlier, explained in Apheresis: Collecting Your Cells for CAR-T. Families often count only the admission and are caught out by the two trips.
Said plainly, before anything else: CION Cancer Clinics does not provide CAR-T cell therapy or any other cell therapy. We do not administer it, stock it or manufacture it, and we quote no price for it. This page exists so your family can plan realistically for what an accredited centre will ask of you, and so we can point you to one if your diagnosis is a case where CAR-T is genuinely on the table.
Did you know?
Most cell-therapy units ask patients not to drive for about eight weeks after the infusion, because the neurological effects of this treatment can appear suddenly and without warning. That single rule quietly decides a lot of a family’s logistics — someone else has to be able to drive, at any hour, for the whole stay.
What happens on each day of the CAR-T hospital stay?
Admission, a short conditioning chemotherapy course, the infusion itself, then close monitoring. The infusion takes under an hour and is the least eventful part of the whole admission. Everything before it is preparation, and everything after it is watching.
| Stage | Where you are | Typically takes |
|---|---|---|
| Admission, baseline tests, consent and a line placed | Inpatient | 1–2 days |
| Lymphodepleting chemotherapy, to make room for the new cells | Inpatient | About 3 days |
| Rest days before infusion | Inpatient | 1–2 days |
| The infusion itself (Day 0) | Inpatient, at the bedside | Usually under an hour |
| The close-watch window — observation for reactions | Inpatient, the critical period | 7–14 days |
| Discharged, but living near the centre with a caregiver | Accommodation within about an hour | 2–4 weeks |
| Review visits tapering off, then clearance to travel home | Outpatient, near the centre | Decided visit by visit |
| Long-term follow-up after a gene-modified cell therapy | Home, with scheduled visits | Years, as regulators require |
A stay of this shape is not comparable to a chemotherapy admission, and it is not the same as a transplant admission either. If you are weighing the two pathways, CAR-T vs stem cell transplant sets the admissions, the recovery and the demands on the family side by side.
What monitoring happens while you are admitted?
Temperature around the clock, vital signs several times a day, and short neurological checks every few hours. Bloods are drawn daily. Fever is the first sign the team is looking for. A change in handwriting or a slip in attention is the second. Both are checked deliberately, not casually.
| What is checked | Typically how often | Why it matters |
|---|---|---|
| Temperature | Every few hours, day and night | Fever is usually the first sign of cytokine release syndrome |
| Blood pressure, pulse, oxygen saturation | Several times a day, continuously if unwell | A falling blood pressure or oxygen level signals a reaction progressing |
| Neurological check — orientation, counting, a handwriting sample | Every few hours in the first two weeks | Handwriting change and confusion are often the earliest neurological signs |
| Full blood count | Daily | Counts fall after conditioning; transfusion and infection risk are managed on these numbers |
| Kidney and liver function, electrolytes | Daily to alternate days | Organ strain shows here before it shows in how you feel |
| Inflammatory markers such as CRP and ferritin | Daily to alternate days | Used alongside symptoms to grade a reaction and decide treatment |
| Cultures, chest imaging, ECG | Whenever fever or a new symptom appears | Infection and a reaction can look identical at the start |
| Weight and fluid balance | Daily | Fluid shifts are part of how severe reactions are recognised and managed |
Monitoring does not stop at discharge. For the weeks you remain near the centre, the caregiver takes temperatures at home on a fixed schedule and the unit gives a number to call at any hour. Guideline bodies including NCCN and ESMO describe this close-observation period as a defining requirement of cell therapy, which is also why only accredited units are permitted to deliver it.

CION does not provide CAR-T cell therapy. We do read your reports, explain what an admission would demand of you, and point you to an accredited centre when that is the right next step.
Can family stay with the patient during CAR-T?
Yes — and at most centres one adult caregiver is not optional but required, 24 hours a day, through the admission and for weeks after discharge. Visiting is usually limited to that one named attendant while blood counts are low. Plan for one person at the bedside, not a family group.
What the caregiver is actually asked to do. Take and record temperatures on a schedule. Notice confusion, unusual sleepiness, a word coming out wrong, a handwriting sample that has changed. Get the patient back to the centre immediately, at any hour, without waiting for morning. Manage medicines, food safety and fluids while counts are low. Units train the caregiver before discharge and often ask them to sign that they understood the instructions.
Why one person is rarely enough for eight weeks. The role is unbroken and exhausting, and the caregiver also has to eat, sleep and handle paperwork. Families who cope best send two adults and rotate, or arrange a second person to arrive for the discharge period. If only one attendant can be in the room, the second can still shop, cook, queue at the billing counter and drive.
Children, elderly relatives and large family groups. Cell-therapy units restrict visitors during the low-count weeks for good reason — a common household infection is a serious event for someone whose counts have not recovered. Expect video calls rather than visits for part of the stay, and prepare children for that before you leave home rather than at the hospital door.
How do you plan two months in another city?
Almost every family doing this is far from home, because only a handful of centres in India are accredited to deliver cell therapy. Six practical decisions decide whether the stay is manageable or chaotic. Make them before you travel, not from a hospital corridor.
-
Ask the centre for its distance rule in writing
Units set a limit — commonly staying within about an hour of the hospital after discharge. That number decides your accommodation, so get it before you book anything. Ask how long the rule applies for.
-
Book accommodation you can extend week by week
A serviced flat with a kitchen beats a hotel room, because food safety matters while counts are low. Never book a fixed non-refundable block — a delayed batch or a complication moves every date.
-
Name two caregivers, and a driver for the night
One trained attendant at the bedside, one to relieve them, and a way to reach the hospital at 2 am. The patient will usually be told not to drive for about eight weeks, so this cannot be left to chance.
-
Budget for living costs separately from the treatment
Rent, food, travel and lost income for two months are a real second bill, and families routinely forget them. Amounts vary by city; treat any figure you are quoted as indicative, as of August 2026.
-
Carry the full record, and a set of copies
Biopsy and marrow reports, immunophenotyping, imaging, every line of treatment, insurance papers, ID and address proof. Keep a scanned set in the cloud so a missing file never costs you a day.
-
Settle work leave, school and dependants before you go
Two months is long enough that it cannot be handled by phone. Arrange care for elderly parents or young children at home, and tell employers a range rather than a date.
What can make the stay longer than planned?
Assume the schedule will move. These are the usual reasons, and none of them means something has gone wrong with your planning.
- A cytokine release reaction needing treatment — managed in the unit with specific medicines, and in intensive care if it is severe. Days to weeks.
- Neurological effects — confusion, difficulty finding words or drowsiness are watched closely and treated in hospital, never at home.
- Blood counts that stay low — transfusion support and infection risk keep people in beds after the reaction window has passed.
- An infection during the low-count weeks — common, expected, and treated with antibiotics in hospital rather than at the accommodation.
- Manufacturing or scheduling delays — a batch that fails release testing restarts the pathway from collection and moves every date after it.
- Living far from the centre — units keep patients in longer when going home is not safe if a fever starts overnight.
What happens after you are finally cleared to travel home — immunity, vaccinations, infection precautions and the follow-up schedule — is covered in Life After CAR-T: Recovery, Immunity and Follow-Up. Long-term data after gene-modified cell therapy is still maturing, which is exactly why regulators require years of follow-up.
Does CION provide CAR-T cell therapy?
No. CION Cancer Clinics does not administer, stock or manufacture CAR-T or any other cell therapy, and quotes no price for it. If a page, an agent or a forwarded message tells you otherwise, it is wrong.
What we do is read your reports and give you a straight answer: whether your diagnosis is even in a category where CAR-T gets discussed, what an accredited centre would realistically ask of your family, and what the treatment you have already been offered is worth as a written second opinion. Where referral to an accredited cell-therapy centre is the right next step, we will say so and help you prepare the record before you travel.
The immunotherapy given as day care at CION Cancer Clinics is checkpoint-inhibitor treatment — a different class of treatment, with a different schedule and a different side-effect pattern, and no admission of this kind. Response-assessment PET-CT during that treatment is coordinated at partner imaging centres rather than owned by CION. Our first consultation is free, takes 45 minutes, and carries no commitment to start treatment anywhere.
