answer:“For, even if the rule is justified and codes of ethics are explicit in this regard, the rule doesn’t hold up in everyday life, as most physicians have already broken the rule at one time or another during their careers. Proof of this came in a survey3 conducted in 2006 among physicians in Montreal, which revealed that most of them had already prescribed laboratory tests (80%) and medications (60%) for themselves. And as it is unlikely that this was always only in emergencies or for minor illnesses, it is plausible that the phenomenon of self-treatment occurs much more frequently than we think and much more often than we admit.” Pub Med
