The hour-by-hour timeline
- 7:30 AM
Arrival
Check in at the nuclear medicine reception. ID, paperwork, and pre-treatment briefing.
- 8:00 AM
Vitals and IV
Blood pressure, temperature, weight, IV line placed (usually in your arm). Hydration starts.
- 8:30 AM
Final eligibility check
Blood test results reviewed. Your nuclear medicine physician confirms you're ready to proceed.
- 9:00 AM
Pre-medications
Anti-nausea medication, sometimes other supportive drugs. For Lu-177 DOTATATE therapy: octreotide pre-medication if functional tumor.
- 9:30 AM
Amino acid begins (Lu-177 DOTATATE therapy only)
A slow 4-hour infusion of lysine + arginine to protect kidney function. Some nausea is normal — anti-emetics help.
- 10:00 AM
Lutetium infusion
The treatment itself: 30 minutes through your IV. You feel nothing during the infusion.
- 10:30 AM – 1:30 PM
Observation
You rest in a shielded room. Frequent hydration. Bathroom breaks (urine carries some Lu-177).
- 1:30 PM
Optional SPECT scan
Some centers perform a post-treatment scan to visualize where the medicine went. ~30 min.
- 2:00 PM
Radiation safety briefing
Written and verbal instructions for the next 3–5 days. Distances from family, urination guidance, sleeping arrangements.
- 2:30 PM
Discharge
You go home. Most patients feel only mild fatigue. Some feel fine. A few feel queasy.
What you'll feel — at each stage
Before
Mild anxiety is normal. Many patients sleep poorly the night before cycle 1. By cycle 2–3, this fades. Eat a normal breakfast. Drink water on the way.
During the IV setup
A typical IV placement — a brief pinch. The IV stays in for the whole day.
During the amino acid infusion (Lu-177 DOTATATE therapy)
The most uncomfortable part for many patients. The amino acid solution can cause nausea, occasional vomiting, and a metallic taste. Anti-emetics manage this well in most cases. Sip water, breathe slowly, distract yourself with a book or show.
During the Lutetium infusion
You feel nothing. The medicine is given through your existing IV over 30 minutes. Most patients chat, read, or scroll their phone.
During observation
Quiet. You rest in a chair or recliner. Staff check in periodically. You urinate often. Most patients feel fine, just bored.
Discharge
Mild fatigue is common; nausea is occasional. Most patients are well enough to ride home (with someone else driving). A small percentage feel queasy and need a quiet evening.

Frequently asked questions
Can someone come with me?
Yes, most centers allow a caregiver during the non-restricted portions of the day. Once Lu-177 is administered, you'll be in a radiation-shielded area where visitors are limited. They can usually wait in a nearby room and rejoin you for discharge.
What if I need to use the bathroom during the infusion?
You can. The IV is portable; staff will help you with the line. You'll be using the bathroom a lot after the Lu-177 — that's the point (flushing unbound medicine).
Can I drink coffee or eat during the day?
Water and small snacks are usually fine. Coffee can be limited if you're already nauseated. Heavy meals are best saved for after discharge.
Should I take my regular medications on treatment morning?
Confirm with your team in advance. Most medications are continued; some (like long-acting somatostatin for NETs) are paused. Bring your medication list to every visit.
What if I feel unwell during the day?
Tell staff immediately. They're prepared for nausea, lightheadedness, and other common feelings. They can give additional medication or pause infusion. You won't be 'wasting their time.'
When can I drive home?
Most centers prefer you arrange transport, not because driving is forbidden but because some patients feel fatigued. If you must drive, give yourself a buffer of an hour or two after discharge before getting on the road.
