Ideally all doctor-patient discussions about drugs should involve the doctor providing info about the drug's goals, and pros and cons, and other ways to achieve the same goals, and the patient saying what they want and how relevant symptoms and drugs have been for them. Patients can request or decline drugs for any reason. Doctors can recommend drugs or decline requests for them, but when declining they have a duty to explain the reasons, answer questions, and offer alternative approaches where possible. If your doctor doesn't do this, try asking them to, and if they don't do it to your satisfaction, see a different doctor. They are being paid to provide a service to you, not to treat you like a child because you have less general medical knowledge than they do. That is the old approach, and not all doctors have caught up yet.
