Rantac and ranitidine same?

Yes. Rantac is a brand name for ranitidine. Ranitidine is the generic drug; Rantac is simply one brand that sells it.

A few important notes:
- Ranitidine is an H2 blocker used to reduce stomach acid (for ulcers, gastritis, GERD, heartburn).
- In many places, ranitidine products have been withdrawn or replaced due to concerns about NDMA, a potential carcinogen. Some markets still allow ranitidine under careful monitoring or have switched patients to alternatives (like famotidine or proton pump inhibitors).
- If you’re currently taking Rantac or ranitidine, talk to your healthcare provider about safe alternatives and whether you should continue, switch, or stop. Don’t start or stop based on online advice without professional guidance.
- Check the product label for the active ingredient. If it says ranitidine (or ranitidine hydrochloride), it’s the same active drug, just a different brand name.
