Where is prilosec manufactured?

There isn’t a single manufacturing location for Prilosec. Omeprazole (Prilosec) is made by multiple manufacturers around the world, and the exact plant can vary by batch, country, and whether you’re taking the prescription brand or an OTC/generic version.

What to check:
- Look at the drug packaging for lines like “Manufactured by,” “Manufactured for,” or “Distributed by” which will list the company and the city/country.
- In the US, Prilosec OTC is marketed by Procter & Gamble and many of the generic omeprazole products are produced by various manufacturers.

If you can share the exact product name (Prilosec prescription vs Prilosec OTC vs a generic) and the label details, I can help identify the likely manufacturer from the packaging.
