Antacids neutralize existing stomach acid and offer rapid but comparably short-term relief of heartburn, acid indigestion and sour stomach.
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 left 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.
Rolaids tablets come in many different flavors, including original peppermint, cherry, freshmint, fruit, tropical, punch, cool mint, berry, and apple.
The active ingredients are calcium carbonate (550 mg) and magnesium hydroxide (110 mg). The inactive ingredients are dextrose, flavoring, magnesium stearate, polyethylene glycol, pregelatinized starch, sucralose and sucrose. The new Chattem varieties have increased the amount of the active ingredients in the product, up to 1000 mg of calcium carbonate and 200 mg of magnesium hydroxide for the “ultra strength” varieties.
Minor side effects may include constipation or stomach cramps. Serious side effects include loss of appetite, vomiting, dizziness, and headache.
