Alka-Seltzer, the #1 effervescent brand for heartburn relief, introduces Fizzy Melts, a new antacid dietary supplement that doesn't require water to activate. Compact and convenient, Fizzy Melts fit easily in pockets, purses, and glove compartments. When heartburn, acid indigestion, or an upset stomach strikes, simply pop two mixed-berry flavored tablets on your tongue for quick relief without the chalky texture. Suitable for adults and children 12 years and older, Fizzy Melts provide fast, on-the-go relief.
