Is prilosec and omeprazole the same thing?

Yes. Prilosec is the brand name for the drug whose generic name is omeprazole. They’re the same medicine; Prilosec is just the brand, and omeprazole is the generic name.

A few quick notes:
- Both Rx and OTC versions exist; dosing can differ by formulation and country.
- In other places, the same medicine may be sold under different brand names (for example, Losec is another brand name used in some countries).
- If you’re taking other medicines (e.g., clopidogrel, warfarin) or have specific health conditions, check with a clinician or pharmacist about potential interactions or appropriate dosing.
- Long-term use of PPIs like omeprazole can affect absorption of certain nutrients and increase some risks, so use as directed.

If you want, tell me your country and whether you’re looking at OTC or Rx, and I can tailor dosing and usage info.
