How the FDA Actually Declares and Resolves a Drug Shortage
A drug shortage designation follows a specific legal and evidentiary process, not a simple observation that a pharmacy is out of stock.

Federal law requires manufacturers to notify the FDA of anticipated supply disruptions for certain drugs, and the FDA assesses whether demand exceeds supply capacity across the market before formally listing a drug shortage.
Resolution follows a similar evidentiary process
A shortage is generally considered resolved when the FDA determines that manufacturer supply can meet current and projected demand, based on data from manufacturers rather than anecdotal reports of individual pharmacy stock-outs, which can lag behind the official determination in either direction.
Why local stock-outs can outlast the official status
An individual pharmacy or region can experience a local stock-out even after a national shortage is declared resolved, due to distribution timing — which is a common source of confusion when a patient can't find a drug the FDA lists as available.
