(CNN) The United States has its first novel coronavirus-related drug shortage, according to the US Food and Drug Administration. The maker of an unnamed drug that has recently been added to the FDA Drug Shortages list told the agency that the shortage is due to the novel coronavirus.

On Tuesday, the FDA warned that these types of shortages could happen, and said it was monitoring the situation closely. The agency identified 20 drugs that either solely sourced their active pharmaceutical ingredients, or produced finished drug products, from or in China.

The unnamed company that notified the FDA about a shortage said the problem is the result of an issue with the manufacturing of an active pharmaceutical ingredient used in the drug.

The US relies heavily on Chinese-made drug ingredients, medical devices and drugs that are used in humans and animals. As of 2018, China ranked second among countries that exported drugs and biologics to the US, and ranked first for medical devices, according to the FDA.

The agency said Tuesday it has been in touch with 180 manufacturers to remind them that the companies have a regulatory obligation to notify the FDA if they anticipate any disruption to drug supplies. The agency asked companies to evaluate their supply chains in light of the coronavirus outbreak.
