Sun Pharma's US subsidiary Caraco Pharmaceutical Laboratories initiated the voluntary recall on April 9, the US Food and Drug Administration (FDA) said in an enforcement report for the week of July 2.
The vials were manufactured by Sun Pharmaceutical Industries, it added.
The firm-initiated class-II recall, which is ongoing, is due to "lack of assurance of sterility: a particle excursion for a different batch of the same product may lead to a lack of sterility assurance," the FDA said.
Shares of Sun Pharma closed at Rs 706.35 on the BSE, up 1.79 per cent.
