" Starting today, the millions of people who suffer from frequent heartburn and acid indigestion can once again turn to Rolaids to help relieve their symptoms." Rolaids is sold in retail stores across the United States and is available in both tablets and a new liquid form. The liquid is a first for the brand, as is new Ultra Strength formulation in both tablets and liquid. Ultra Strength Tablets and Liquid deliver Rolaids' strongest level of acid neutralization. "Incorporating Rolaids into Chattem's portfolio further strengthens Sanofi's position as a leader in the U.S. consumer healthcare sector and helps to further diversify our category offerings," said Anne Whitaker, President, North America Pharmaceuticals, Sanofi . Chattem will support the re-launch of Rolaids with a fully integrated marketing campaign featuring chef and restaurateur Guy Fieri. The campaign includes national television spots that include Fieri and re-establishes one of the most recognized advertising taglines of all-time – How Do You Spell Relief? R-O-L-A-I-D-S. Heartburn occurs when the opening between the stomach and esophagus malfunctions and allows stomach acid to enter the esophagus. More than two-thirds of all U.S. adults experience heartburn at least once per month.
