Sunstar Americas Expands Voluntary Recall of Paroex® Chlorhexidine Gluconate Oral Rinse USP

January 4, 2021

Due to potential bacterial contamination, the company is voluntarily recalling a larger batch of its prescription oral rinse.

Sunstar Americas recently announced that it has expanded its voluntary recall to cover a larger batch of its Paroex® Chlorhexidine Gluconate Oral Rinse USP, 12% due to potential contamination with the bacteria Burkholderia lata.

The original recall was issued in October 2020, and it has now been expanded to include products bearing an expiration date from 12/2020 – 09/2022. The infected products could potentially lead to oral, or systemic infections that could become life-threatening.

To date, 29 adverse events related to this recall have been reported to Sunstar. Affected patients tested positive for Burkholderia lata infections. Use of the contaminated product on patients with pre-existing respiratory conditions, including those infected with coronavirus disease 2019, is particularly unsafe.
