From the manufacturer's website:
Whether brought on by the stress of the moment, that burger-and-fries combo impersonating your lunch - or a combination of both - your stomach usually lets you know when it's not happy. Too much acid tangling with the high-fat food you just ingested, or too many demands on your limited time. Whatever the cause, the roiling you feel and hear is a clue you need help. (If the rumbling is loud enough, it's a clue to others, too.) Good Sense Dual Action Famotidine Complete Mint Chewable Tablets can help. The active ingredients reduce the acid in your stomach, and quiet the rumbling. Famotidine (acid reducer) teams up with calcium and magnesium (neutralizing the acid already in your stomach) to help in your bout against occasional heartburn and sour stomach.
