When a verbal or telephone order is given, there is always the chance that the person receiving the order will not hear the order correctly or will misinterpret what is said. If there is any delay between the time the order is given and time it is written or entered into the computer, there is also the risk that the order will not be remembered or entered correctly. With chemotherapeutic drugs, doses must be exact because an unintentional overdose can result in severe harm, or even death, for the patient. Never permit or accept verbal and telephone orders for initial orders or changes when dealing with chemotherapy medications.
