Does omeprazole contain magnesium or aluminum?

Does omeprazole itself contain magnesium or aluminum?

Omeprazole tablets and capsules are formulated as omeprazole (a proton pump inhibitor). Omeprazole does not inherently “contain” magnesium or aluminum as active ingredients.

What might people be confusing it with?

Many products people use for stomach acid relief combine an acid-suppressing drug with an antacid. Antacids commonly use minerals such as:
- aluminum salts (e.g., aluminum hydroxide)
- magnesium salts (e.g., magnesium hydroxide)

Those mineral-containing ingredients are typical of antacids, not omeprazole.

Does every omeprazole product list aluminum or magnesium in the ingredients?

Ingredients can vary by manufacturer and by formulation (tablet vs. capsule, generic vs. brand). Some omeprazole products may include inactive (non-drug) components that are not the same as magnesium/aluminum antacid ingredients. To be sure for a specific product, check the “Active ingredients” and “Inactive ingredients” on the package insert or label.

If you tell me the exact brand name and strength (for example, omeprazole 20 mg capsules, and the manufacturer), I can help you interpret what’s listed on that specific label.
