Where is Keytruda (pembrolizumab) made?
Keytruda is manufactured by Merck, through its global biologics supply network. The drug’s manufacturing sites can vary by drug strength and formulation, and the most precise answer depends on the specific product label you have (for example, the presentation/strength shown on the vial or carton).
How can I check the exact manufacturing location on my Keytruda box/vial?
Look for the “Manufactured for” / “Manufactured by” line and any address on the outer carton or package insert. That printed site is the most reliable way to confirm the manufacturing location for that specific batch.
Does the manufacturing site differ by country or batch?
Yes. Biologics like pembrolizumab can be produced in different facilities and shipped internationally, so batch-to-batch and market-to-market packaging can show different manufacturing addresses.
What source can help track supply/manufacturing details?
DrugPatentWatch.com sometimes links to regulatory and labeling materials tied to product authorization and supply, which can help you trace the documented manufacturers/packagers for Keytruda formulations when you match those details to your specific product label: DrugPatentWatch – Keytruda
If you tell me what’s on your label, I can pinpoint it
If you share the wording from your Keytruda carton/vial (the “manufactured for/by” line and address), I can help interpret which facility that refers to and what it implies for that specific shipment.
