Chalk it up to another wonderful RECALL; actually recallS:
"Rolaids was a brand of antacid produced by McNeil Consumer Healthcare, a subsidiary of Johnson & Johnson. The brand was acquired from Pfizer Consumer Healthcare as part of a merger in 2006. It was invented by American chemist Irvine W. Grote in the late 1920s. As a result of multiple recalls, production was suspended by the manufacturer in 2010.
As of January 2012, the trademark for the Rolaids brand belongs to Chattem, a subsidiary of Sanofi."
