The recall will temporarily disrupt supplies of the generic Lipitor to the U.S., Ranbaxy, a unit of Japan's Daiichi Sankyo Co, said in a statement.
The investigation in this regard is expected to be completed within two weeks, after which the company expects to resume supplies, it said.
Ranbaxy shares extended losses and were down 1.87 percent by 0553 GMT.
