Do over the counter antacid pills have a good shelf life?

Yes, over-the-counter antacid pills generally have a good shelf life, typically ranging from two to three years when stored properly. It's important to check the expiration date on the packaging, as potency may diminish after this date. To ensure maximum effectiveness, store them in a cool, dry place away from moisture. Always consult the packaging or a pharmacist for specific guidance on shelf life.
