Acid reducer : Over the counter medications sold by Costco should be regulated and checked for safety according to US government regulations. To be sure you can contact Costco.

Drug safety: If FDA approved and not expired they should be safe to take. Otherwise no drug has ever been proven safe to be taken indefinitely with no physician supervision. A recent recall addressed a different drug in same class, Ranitidine.
