Do not use if package is damaged (crossed-out box)

The standard’s wording, as the sources below reproduce it:

“Indicates a medical device that should not be used if the package has been damaged or opened and that the user should consult the instructions for use for additional information.”

ISO 15223-1:2021, 5.2.8 · ISO 7000-2606

What it means for you

Check the pack before use: a tear, a hole, a broken seal or a wet pouch means the device inside can no longer be relied on — for sterile products the pack is what keeps them sterile. Boston Scientific notes the symbol can also mean “Do not use if the product sterile barrier system or its packaging is compromised”.

Whether a device is right for you is a question for your pharmacist, nurse or doctor.

What it looks like
A circle with a diagonal bar over a box whose corner is torn open.
Where you see it
Sterile pouches and blister packs: dressings, catheters, test swabs, contact lenses, syringes.
Other names
do not use if package is opened or damaged; check package integrity

What it does not tell you

It does not say an intact pack is sterile after the use-by date, and it does not say what counts as damage for a specific product — the instructions do.

Often confused with

Indicates a medical device that is intended for one single use only.
