Johnson & Johnson’s voluntary recall of Concentrated Motrin Infants’ Drops remains in effect. The recall, which was originally issued last month, involves 200,000 bottles thought to contain tiny plastic particles. Although company officials believe adverse health effects are unlikely, they have advised consumers to stop using the product immediately.

According to the Associated Press, the recalled products may contain traces of polytetrafluorethylene (PTFE), a type of plastic used in Teflon coatings. In an update released Sunday, distributors said that J&J’s McNeil Consumer Healthcare Division had traced the contamination to a third-party supplier of ibuprofen – the active ingredient in Motrin and many other over-the-counter pain relievers.

“Out of an abundance of caution, McNeil is voluntarily recalling the three lots released to the market made with the same batch of active ingredient,” the company wrote. “McNeil has worked with the third party to ensure that corrective measures are currently in place and are effective. The potential for adverse medical events related to the reason for this recall is not likely.”

Since 2009, McNeil has issued about 40 recalls involving common analgesics like Tylenol, Motrin, and Zyrtec. In April 2010, the manufacturer issued its largest-ever recall of children’s pain relievers, pulling more than 130 million units off the shelves.

The recalled products are Concentrated Motrin Infants’ Drops Original Berry Flavor ½ fl oz bottles. The units can be recognized by their lot numbers:

- DCB3T01

- DDB4R01

- DDB4S01
