A physician indicating that a brand name medication is required must provide a clear directive to the pharmacist. The method that is not acceptable involves leaving the decision to the pharmacist's discretion. This is because such ambiguity can lead to the substitution of a generic medication, which the physician does not intend.
In the context of acceptable methods, when a physician handwriting a note on the prescription, signing 'Dispense as Written', or making a note on an electronic prescription, all provide clear instructions that the specific brand name medication must be dispensed. These methods ensure that there is no misunderstanding regarding the physician's intent for the patient’s medication, thus complying with legal and clinical standards.
Leaving it to the pharmacist's discretion creates uncertainty and does not fulfill the requirement for specificity in the physician's order. Therefore, it is not an acceptable method for indicating that a brand name medication is required.
