Rolaids is an American brand of calcium and magnesium-based antacid produced by Chattem. It was invented by American chemist Irvine W. Grote in the late 1920s, and originated with manufacturing in Chattanooga, Tennessee, under one of Chattem's forerunner companies, which manufactured the brand for Warner-Lambert; Warner-Lambert merged with Pfizer in 2000. In 2006, McNeil Consumer Healthcare, a subsidiary of Johnson & Johnson, acquired the brand from Pfizer Consumer Healthcare. In 2013, McNeil sold the brand to Sanofi, following a two-year period where the brand was pulled off the market due to product recalls resulting from quality control and manufacturing issues that also kept former fellow antacid brand Pepcid AC's "chewables" product and other fellow McNeil products like some varieties of Tylenol off store shelves for the same period. Rolaids returned to the market at the beginning of September 2013 under Chattem ownership with new packaging, trade dress, and a new liquid variety. More information...
