Pfizer is recalling 191,000 bottles of Lipitor cholesterol fighter following reports of a musty odor coming from some bottles of the medicine made by a third-party supplier.

The world's largest drugmaker said the recall involved seven lots of 40 milligram Lipitor, as well as three other lots of the medicine supplied to a Canadian generic drugmaker. Five of the seven recalled lots of the branded medicine were in the United States, while two were recalled from Canada, Pfizer said.

The recall was initiated after the company received three reports from consumers complaining about the musty odor.

The health problem reported by the consumer was found to be not likely to be related to the odor problem.

The U.S. Food and Drug Administration is aware of the recall and monitoring the situation, Pfizer said.
