How to find out if your medication has been recalled

Most people assume that if a medicine they take is recalled, someone will tell them. A letter, a phone call from the pharmacy, something on the news. For the largest and most dangerous recalls, that sometimes happens. For most of them, it does not.

Recalls are graded, and the grade decides who hears

The FDA sorts drug recalls into three classes by how much harm the problem could cause. Class I is the serious end — a reasonable probability of serious harm or death. Class II covers problems that might cause temporary or reversible harm. Class III covers issues unlikely to cause harm at all, such as a labelling or packaging defect.

Class II is where most recalls live, and it is also where the notification chain tends to stop. A recall notice travels from the manufacturer outward — to wholesalers, then to pharmacies. Whether it goes the last step to the patient depends on the pharmacy's own systems, whether your contact details are current, and whether anyone connects the recalled lot to your particular fill. The FDA itself has acknowledged that recalls frequently do not reach the patient.

What is actually being recalled

A recall almost never covers an entire drug. It covers specific lots from a specific manufacturer — sometimes a single batch. That is why 'is my medicine recalled?' has no useful yes-or-no answer without two pieces of information:

• The NDC, the National Drug Code on the pharmacy label, which identifies the manufacturer, drug, strength and package size
• The lot number, printed on the manufacturer's packaging — the box or the stock bottle, not always the pharmacy vial

With the NDC you can tell whether your product is involved at all. With the lot you can tell whether your particular batch is.

Where to check

The FDA publishes recalls and safety alerts on its own website, and its enforcement database is public. Both are searchable and both are authoritative. Both also assume you already know to go looking — which is the real problem. A recall you never think to search for is a recall you never find.

The 2D barcode changes what is possible

Prescription packages increasingly carry a square 2D barcode alongside the old striped one. Under the Drug Supply Chain Security Act, that code carries the product identifier, the serial number, the lot and the expiration date. Scanning it means the lot number does not have to be squinted at and typed — which is what makes lot-level recall checking practical for a person rather than a warehouse.

If a medicine you take is recalled

Do not simply stop taking it and wait. For many medicines, stopping abruptly carries its own risk, and a recall is often about a manufacturing defect rather than a danger in every dose. Contact your pharmacist or prescriber, tell them the drug, the NDC and the lot, and ask what they want you to do. They can usually replace the medicine the same day.
