I have a script for impressive Dr 40 mg capsule (prilosec) the pharmacy had half my regular pills but the other half was a different kind and there was a note staying they are the same just a different color but they are not working like the other pills did. I looked them up on here by the description of the pill and they don't show it the capsule has O M on the top and 40 on the bottom part of the capsule. What should i do?
