What this bill does
In plain words · AI-written from the official summaryTracks risks in America's medicine supply
The FDA keeps a list of medicines that are essential to always have on hand—especially drugs needed for emergencies, chronic illnesses, and public health crises. This bill requires the FDA to update that list every two years and thoroughly check for weak spots in how these medicines are made and delivered. The FDA and the Department of Health and Human Services would also work together to spot problems in the supply chain and tell Congress what they find.
How it affects you
You might not notice this directly, but it affects everyone who depends on medications. The goal is to make sure that essential drugs—whether for emergencies, ongoing conditions, or future health threats—stay available and don't run out. By identifying supply chain problems early, the government hopes to prevent shortages of the medicines people rely on.

Mapping America’s Pharmaceutical Supply Act or the MAPS Act
This bill requires the Food and Drug Administration (FDA) to continually update its essential medicines list and identify risks and vulnerabilities in the associated supply chains.
In 2020, in response to an executive order, the FDA published a list of essential medicines deemed medically necessary to have available at all times. The bill requires the FDA to update and maintain this list to include drugs and ingredients (1) related to responding to public health threats and emergency incidents, (2) that are of greatest priority for providing health care and are at high risk of shortage, and (3) the shortage of which would adversely affect patients with chronic conditions. The FDA must review the list at least every two years and update it as appropriate.
Also, the bill requires the FDA to conduct a risk assessment of the supply chains for drugs and ingredients on the list and annually report its findings to Congress. The assessment must include information about key manufacturing materials, drugs with primarily foreign or single suppliers, manufacturing capacity, relevant public health and national security risks, and risk mitigation strategies.
Additionally, the Department of Health and Human Services (HHS) must map and monitor relevant supply chains to identify vulnerabilities and provide an annual status report to Congress. HHS must facilitate the secure exchange of information among agencies regarding locations and quantities of production and relevant regulatory actions.
