Like any manufactured drug product, GLP-1 pens are occasionally subject to voluntary recalls tied to specific lot numbers, usually related to device malfunction, dosing accuracy, or sterility concerns identified during manufacturing or post-market surveillance.
Where the lot number is
The lot number and expiration date are printed on the pen itself and on the outer carton. Manufacturer and FDA recall notices typically list the specific affected lot numbers rather than an entire product line.
What to do with a recalled pen
If a lot number matches an active recall, contact the pharmacy that dispensed it and the manufacturer for return or replacement instructions, and check with a prescriber if you've already used doses from that lot and have safety questions.
