- Lyophilised powder, sealed vial, left at room temp overnight
- 20–25°C
- 8–12 hours
- 10–20% loss
- Refrigerate immediately; use within 30 days; expect slightly reduced efficacy
- Reconstituted solution, left at room temp overnight
- 30–50% loss
- Significant degradation likely; consider replacement if dose precision required
- Lyophilised powder, shipping delay in summer heat
- 28–35°C
- 24–48 hours
- 25–40% loss
- Contact supplier for replacement; structural integrity compromised
- Reconstituted solution, refrigerated but temp spiked to 12°C for 2 hours
- 10–12°C
- 2 hours
- 5–10% loss
- Minimal impact; continue use as planned
- Lyophilised powder, frozen at −20°C then thawed at room temp
- −20°C → 22°C
- Thaw cycle
- Negligible if slow thaw
- Acceptable if thawed slowly; avoid repeated freeze-thaw cycles
