Actually pharmacies are supposed to be paying attention to the scripts you’re filling and alert you doctor if there’s a potential problem. Like if the script he wrote has a history of reacting with something else you’re on. Or that this is your 5th active script for oxy and maybe that’s a problem.
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”.
