Does omeprazole contain aluminum?

Does omeprazole tablets or capsules contain aluminum?

Omeprazole is a proton pump inhibitor, and the drug substance itself does not contain aluminum. What’s more likely to vary across products is the capsule/tablet excipients (inactive ingredients), which can differ by brand and country.

Could aluminum show up from inactive ingredients or packaging?

If a specific omeprazole product lists aluminum-containing excipients (or uses certain formulations where aluminum is present), then aluminum could appear in the finished medication. But that would be product-specific, not inherent to “omeprazole” as a medication class.

How can you check an omeprazole product for aluminum?

Check the “Inactive ingredients” section on the package insert or the label for your exact brand (and strength). If you tell me your brand name (and strength, like 20 mg or 40 mg) and country, I can help you interpret what that product’s label says about excipients.
