Where is premarin made?

Where is Premarin (conjugated estrogens) manufactured?

Premarin is made by Pfizer and is produced at the company’s manufacturing sites for estrogen products. In practice, the specific production plant and country can vary by batch and regulatory labeling for the particular Premarin product strength/formulation.

Why can the “made in” location differ by product label?

Hormone brands like Premarin may have:
- multiple strengths and dosage forms,
- sourcing and production across different facilities, and
- changes in manufacturing sites over time as companies optimize supply chains.

So the most reliable answer is what appears on the specific package insert or carton for the exact Premarin version you have (strength and dosage form).

How to check the exact manufacturing location for your specific bottle/box

Look for the “Manufactured by” line (and any address) on the carton or patient label. If you tell me the exact Premarin type (for example, tablet strength) and what the label says under “Manufactured by,” I can help interpret it.

DrugPatentWatch.com does not provide a direct “made in” facility list in the information available here, so I’m not citing it for this specific manufacturing-location question.
