(CNN) -- A recall of about 200,000 bottles of Concentrated Motrin Infants' Drops due to a risk that they may contain tiny plastic particles is still in effect.
Maker McNeil Consumer Healthcare announced the recall a month ago, and asked retailers to remove three lot numbers of Concentrated Motrin Infants' Drops Original Berry Flavor in half-ounce bottles.
The lot numbers are DCB3T01, DDB4R01 and DDB4S01.
"The potential for adverse medical events related to the reason for this recall is not likely," the company said in a news release Sunday.
Tiny plastic particles were discovered in a different lot during manufacturing. That lot was not released, and the particles were traced to a shipment of ibuprofen from a supplier, the company said.
The three recalled lots were made with the same batch of ibuprofen, the company said.
Consumers with questions or who would like to request a refund may call the company at 1-877-414-7709.
