Johnson & Johnson’s consumer division is recalling more than 53 million bottles of over-the-counter products including Tylenol, Motrin and Rolaids after reports of an unusual odor, expanding on an issue that led to a Tylenol recall last year.

The latest voluntary recall, which drew a sharp rebuke from U.S. regulators on Friday, followed consumer reports of “an unusual moldy, musty, or mildew-like odor that, in a small number of cases, was associated with temporary and non-serious gastrointestinal events,” the company said. Such events included nausea, stomach pain, vomiting and diarrhea.
