Tums are one of the most common over-the-counter antacids for heartburn and indigestion. But if you find an old bottle in your medicine cabinet, you may wonder: do Tums expire? The short answer is yes. Like all medications, Tums have an expiration date printed on the packaging. While they don’t suddenly become dangerous after that date, their effectiveness can decline over time.
In this article, we’ll explain how long Tums last, what happens after expiration, how to store them properly, and which storage products can help extend their shelf life.

Do Tums Expire?
Yes, Tums have an expiration date, typically 2–3 years from the manufacturing date. After that date, the active ingredient (calcium carbonate) may lose potency, meaning the tablets may not work as well to relieve heartburn or indigestion.
Are Expired Tums Safe?
- Not harmful: Expired Tums are generally not toxic, but they may be less effective.
