Does nicotine gum expire?

Yes. Nicotine gum has an expiration date printed on the packaging. It’s a quality and potency date.

- After expiry, the gum may not work as well because the nicotine potency can decline, and texture or flavor might change.
- It’s not usually dangerous to use expired gum, but it’s less reliable for quitting.
- Store it cool and dry in the original packaging; avoid heat, moisture, and sunlight.

If you’re in the middle of a quit attempt or you’re unsure, it’s best to replace expired gum with a fresh supply.

If you share the brand and the date you see, I can help interpret what it means for you.
