I'm a doctor. My patient Bonnie seems to dislike me, so I'm going to stop prescribing her medication to her.
How do you justify withholding medication your patient needs?
It's not right to prescribe medication to a patient who scornfully refuses their meds.
Is she the one who is actively refusing? Have you considered talking to her about it first? Maybe she's having a bad reaction. To just stop a medication regimen without notice sounds dangerous.
I don't need to explain myself or anything else to you.
You obviously know more about the intricacies of medication than I do, but what you said at the beginning made me think that you were stopping this prescription because of hard feelings between you and the patient. Even if this isn't the case, I would suggest referring her to another doctor, and letting them decide if the prescription should be ceased.
