FDA Commissioner Stephen Hahn said the agency has been “closely monitoring” the medical product supply chain “with the expectation” that the outbreak of the novel coronavirus would “likely” have an impact.

“A manufacturer has alerted us to a shortage of a human drug that was recently added to the drug shortages list,” Hahn said in a statement Thursday night. “The manufacturer just notified us that this shortage is related to a site affected by coronavirus. The shortage is due to an issue with manufacturing of an active pharmaceutical ingredient used in the drug.”

“It is important to note that there are other alternatives that can be used by patients,” he added. “We are working with the manufacturer as well as other manufacturers to mitigate the shortage. We will do everything possible to mitigate the shortage.”
