There are very good reasons why a doctor might decide to change a prescription for someone, and listening to the patient over the doctor in some of those cases would not only be a bad idea, it could be potentially fatal or cause long lasting problems.

For example:

- Evidence of abuse of a drug.

- A second prescription which interacts badly with the first.

- Changing health circumstances (pregnancy, some sort of deficiency, failing internal systems, etc).

The correct thing to do in a case like this is to stop and coordinate with the prescribing physician. Having a pharmacist look at some change compared to how things were done prior and have a patient tell them it's a mistake and they should ignore it without consulting the prescribing physician is almost never a good idea.
