Does prilosec have magnesium in it?

Prilosec (omeprazole) itself does not typically contain magnesium as an active ingredient. It’s formulated as omeprazole plus inactive ingredients.

That said, the exact inactive ingredients can vary by formulation and country (and by whether you mean Prilosec OTC vs prescription omeprazole, or capsules vs other versions).

If you tell me:

• the exact product name (e.g., Prilosec OTC, strength like 20 mg),
• and whether you’re in the US (or another country), I can help you check the likely inactive ingredients. If you can also share a photo or the “Inactive ingredients” section from the box, I can confirm whether any magnesium compounds are listed.
