OIT-008 / SOP v2.0
Incident, recall and reassessment
Reaction, suspected deviation or change involving an allergen batch.
Procedure
- In an acute reaction, the clinical emergency plan and appropriate emergency services take priority. The laboratory does not provide an alternative treatment protocol.
- Record product, lot, container, reported intake, timing and available information with privacy protection. Do not automatically assign causality.
- Suspend supply of the suspect batch and notify the responsible pharmacist and clinical team. Check shared raw materials and adjacent work for contamination.
- Preserve samples and data. Examine identity, calculation, mixing, recovery, labelling, dosing device and transport/use conditions.
- Organise recall and reporting to competent bodies where required. Record contacts and reconcile affected quantities.
- Close with documented investigation, CAPA and effectiveness review. Restarting or changing dose is the specialist’s decision, separate from technical correction of a batch.
Edition-specific detail
Investigation distinguishes an expected clinical reaction from identity, dose, contamination or product errors. A negative retained-sample result does not exclude a problem in another withdrawal. Preserve the device, label and available remainder with secure traceability; clinical cofactors are assessed through the responsible specialist.
Stop criterion
Do not resume supply of a suspect product before the required assessment is complete.
