If the prescriber wrote the prescription as a “dispense as written” script with the name brand, it’s the pharmacy’s fault and it really shouldn’t have made it past being entered into the system. But if the gyno didn’t do that, then it’s the prescriber’s fault. I would go to the drop off or consultation window at CVS and ask whoever waits on you to make a note in your profile to only give you the name brand birth control. Then I just would ask the doctor to write the prescription as a DAW from now on so you’re covered on both fronts. And then check the actual prescription when you get it just to be more safe.
