The week after each cycle
Day 0–1 (discharge day and the next)
You feel reasonable. Mild fatigue, possibly nausea (more common with Lu-177 DOTATATE therapy due to the amino acid infusion). Drink plenty of water. Urinate often — and follow your center's urine guidance (flush twice, wash hands well).
Day 2–3
Radiation level still elevated. Continue distance precautions (1 meter from young children and pregnant women). Sleep separately if possible. Use separate toilet if available. Full radiation safety guide →
Day 4–7
Radiation precautions ease. Most patients return to work, exercise, social life. Some mild fatigue persists. Dry mouth (Lu-177 PSMA therapy) may linger.
Week 2–4
Blood counts may dip during this window — your bone marrow is most affected at this time. Most people don't notice; some feel mild fatigue or get easily winded.
Week 5–6 (or 7–8)
Pre-cycle blood tests, possible scan, then next cycle.
Managing common side effects at home
Mild nausea
- Anti-nausea medication as prescribed
- Small frequent meals, bland foods
- Ginger tea, peppermint
- Avoid strong smells, fried/spicy foods initially
Fatigue
- Plan rest periods; don't push through the first 3–4 days
- Light walks improve energy faster than total rest
- Hydration and balanced nutrition support recovery
- Sleep priority — aim for 8 hours
Dry mouth (Lu-177 PSMA therapy)
- Sugar-free gum or candies
- Frequent small sips of water
- Humidifier at night
- Pharmacy saliva substitutes if persistent
- Good dental hygiene is critical (dry mouth increases cavity risk)
Mild diarrhea or constipation
- Stay hydrated
- Fiber adjustments based on direction
- OTC medications usually fine (confirm with team)
Frequently asked questions
When can I resume sexual activity?
Most teams recommend waiting about 7 days after a cycle. Use barrier protection during the first week. Discuss with your medical team for specific guidance.
Can I drink alcohol between cycles?
Light moderate alcohol is generally allowed once you've recovered (after day 7). Discuss with your team. Avoid in the first few days when nausea and fatigue are most likely.
Can I exercise?
Yes — gentle exercise helps recovery. Start light walking from day 2–3, work up to your normal routine within a week. Avoid intense exercise in the first 3 days post-cycle.
Will I feel worse after each cycle?
Most patients don't see cumulative worsening. Some feel cycles get a bit easier as they know what to expect. A small number have cumulative fatigue or blood-count issues that require dose adjustment.
