If you can’t find the expiration date of the product on the packaging, you can either ask the pharmacy to help you figure it out. It is never safe to consume a medication if you think it might have expired.

Also, if you are using the Alka Seltzer liquid gels, they have a slightly lesser shelf life of around two years.
