Which companies make omeprazole (generic and brand)?
Omeprazole is widely manufactured by many generic drug companies because it is an off-patent medicine in most markets. The specific “manufacturers” listed on a bottle or box typically depend on the country and the exact product strength and dosage form (for example, delayed-release capsules vs. tablets).
In the U.S., examples of companies that have marketed omeprazole products include large generic manufacturers and labelers (not always the original maker of the drug substance). If you need a precise manufacturer name, check the package labeling for the “Manufactured by” (or “Distributed by”) line.
How to find the exact omeprazole manufacturer for the product you have
Manufacturers can vary between batches and between re-labelers. To identify the correct one, look for:
- “Manufactured for/with” or “Distributed by” on the carton or bottle label
- The National Drug Code (NDC) number
- The dosage form (capsule vs. delayed-release granules/tablets), since supply chains can differ
If you share the strength (mg), dosage form, and NDC (or a photo of the label text), you can narrow it to the specific company for that exact product.
Are there common brand-name omeprazole products and who makes them?
In many countries, the most recognizable branded omeprazole is Prilosec (and other local brand names). Brand products are typically made by the brand holder and/or contracted manufacturers, but the label will show the responsible firm for the specific product.
Are there multiple versions (enteric-coated, delayed-release) with different makers?
Yes. Omeprazole is commonly sold as delayed-release/enteric-coated formulations so it can survive stomach acid and dissolve in the intestine. Different formulations and strengths can come from different manufacturing sites and companies, even if they contain the same active ingredient.

If you tell me your country, I can narrow the list
“Omeprazole manufacturers” varies by region. Tell me:
- Your country (or where the product was bought)
