(CNN) Kimberly-Clark is recalling regular absorbency U by Kotex Sleek tampons in the United States and Canada after reports of the tampons unraveling or coming apart upon removal.

In some cases, users sought "medical attention to remove tampon pieces left in the body," the recall announcement said.

There have also been a small number of reports of infections, irritation, injury and other problems. People should seek medical attention if they experience symptoms such as vaginal injury, irritation, urogenital infections, abdominal pain, nausea or vomiting.

Lot numbers can be found on the bottom of the tampon packaging.

Recalled products were manufactured between October 7, 2016, and October 16, 2018, and distributed between October 17, 2016, and October 23, 2018. No other Kotex products are affected by this recall, the company said.
