After a cold chain break, what is the recommended action regarding the affected supply?

• A. Return to stock.
• B. Label it DO NOT USE.
• C. Use within 24 hours.
• D. Discard it.

Answer: (B)

When a cold chain break occurs, patient safety hinges on not using products whose stability is uncertain. Refrigerated or frozen medicines may lose potency or become unsafe if their temperature history is compromised, so assuming they’re still usable is risky.

The immediate, recommended action is to clearly label the affected supply as DO NOT USE and keep it separated from usable inventory. This prevents accidental administration while you follow the facility’s policy for disposition. Depending on the item and local guidelines, the next step typically involves returning the product to the supplier or discarding it, but the first and most important action is to mark it clearly and quarantine it so it cannot be used.
