Sunstar Americas, Inc., Expands Voluntary Nationwide Recall of Paroex® Chlorhexidine Gluconate Oral Rinse USP, 0.12%, for Microbial Contamination

Use of the defective product in immunocompromised patients may result in oral and, potentially, systemic infections requiring antibacterial therapy. In the most at-risk populations, the use of the defective product may result in life-threatening infections, such as pneumonia and bacteremia.

SAI received reports of 29 adverse events to date. Affected patients tested positive for B. lata infections, which were typically found in sputum cultures while under treatment for other serious medical conditions. Use of the contaminated product on patients with preexisting respiratory conditions, including those infected with the COVID-19 coronavirus, is particularly unsafe.
