‘Do no harm’ is not even in the Hippocratic Oath, which you probably didn’t take; and looking at the Oath of a Pharmacist, it does not leave you room to creatively interpret prescriptions. You can’t supply tylenol-3s in place of heart medication because the person seems to be in pain, and you can’t supply nothing in place of contraception. You are subservient to the doctor’s order.
Yes. You are not a free agent as the doctor is; you are his liaison. If someone wants contraception and the doctor does not prescribe it, they find another doctor, much like someone feeling like a ham sandwich does not go to a kosher deli.
You are not the sandwich maker or the deli owner. You’re the waiter or the cashier. You bring out the sandwich, you do not choose the menu options.
I don’t know what you do for a living, but allow me to explain this to you. A pharmacist is required to fill a prescription if he feels that it will not harm the patient. I cannot express to you how many times a pharmacist flat out refuses to fill a questionable script. This is usually due to a dosage that is out of line. The pharmacist calls the prescriber and expresses his or her concern. Many times the prescriber will change the prescription, other times they will not. If they can justify to me why they want what they want, I fill the script. If they do not or will not, I don’t. The patient is then free to find a pharmacist that will, much as they are free to find a new doctor, as you mentioned. This is because I am LEGALLY REQUIRED to follow up with prescribers regarding questionable prescriptions. I can be held liable for harm done to my patient by NOT calling and documenting my concerns with a prescriber. This action is referred to as an intervention, and happens many times per day. You may not agree with this, but I assure you that it is standard procedure.
The bottom line is this. A pharmacist is not a robot, doing everything they are told without question. It does not work that way. I have a professional obligation to ensure the safety of the people I serve. We use what is referred to as professional judgement. You cannot believe that a person with a doctor of pharmacy degree, which takes 6 years plus an extensive intership to earn, simply acts as a “waiter or cashier” in your above analogy. If you do believe it, then you are terribly misinformed about this profession.
