(WASHINGTON) -- Pharmaceutical manufacturer Pfizer, announced the expansion of an ongoing recall for Lipitor, a drug intended to lower cholesterol in patients. The decision to expand followed the discovery of more bottles of the drug that give off a musty odor.
The latest recall will included an additional lot of 19,000 bottles of 40 mg Lipitor pills, which will bring the total number of bottles removed from shelves to 360,000.
Pfizer said in a statement that the musty odor is likely coming from a chemical called 2,4,6-tribromoanisole (TBA), which was previously identified in a bottle of Lipitor causing one of the original consumer complaints. The FDA says the health effects of TBA are "minimal," causing mainly gastrointestinal distress in consumers of the product.
The original Lipitor recall began in August, but was only announced in October after additional lots were included. The supplier changed its methods to resolve the problem in August, but Pfizer said the lots involved in the newest recall may have been distributed before then.
"Product filled in bottles made by the supplier prior to those changes may still be on the market, so it is possible that additional recalls could be necessary," Pfizer said.
