Department of Health and Human Services Secretary Alex Azar said the Food and Drug Administration is closely monitoring pharmaceuticals made in China during the coronavirus outbreak.

"To date, we are not aware of any expected shortages and we have aggressively, proactively reached out to manufacturers for that information," he said.

Rep. Kay Granger, the ranking member of the House Appropriations Committee, asked Azar during a budget hearing about what the US is doing to ensure the safety of the American drug supply.

The FDA is reaching out to pharmaceutical and device manufacturers, Azar said.

“The latest fruits of that work show that there are 20 pharmaceutical products we are aware of to date at FDA where either the entire product is made in China, or there is a critical active ingredient that is solely sourced within China, so those would be, obviously, the most targeted to be concerned about," he said.

Azar added, “I'm told there are two manufacturers in Hubei province of pharmaceuticals, but fortunately the manufacturer has a large, large stockpile of supply of advanced production there, but we have to be very alert to this and we have to be candid that there could be disruptions in supplies.”
