Agreed—but the key communication is between the pharmacy and the doctor.
If they have concerns of any kind they should be raised with the doctor and the conversation with the patient should just be “we will talk to your doctor and get back to you”.
Yeah, but it is something they do. My wife’s dealt with that plenty (she had a really annoying pharmacy for a while, that wanted to discuss everything). And they do have the authority to say no we’re not filling that.
