A mouth rinse solution made in a now-shuttered pharmacy unit at the National Institutes of Health Clinical Center in Bethesda, Md., has been quarantined after a nurse discovered particles inside, according to The Washington Post.
The solution was a sugar and water solution made four years ago and was used to evaluate patients' responses to sweets. No one was harmed by the solution, but the NIH is still looking into where the particles in the solution came from.
The solution was prepared in the Pharmaceutical Development Section of the NIH Clinical Center in 2012. That unit of the center was shut down in 2016 after the Food and Drug Administration faulted it for its sterility processes.
The FDA told The Washington Post it is "gathering information to determine if additional action is necessary" in this case.
