When i was nsurg resident in my country, like many other residents in the field, i developed a thinking - we, nsurgeons don't look below the brain and do this and do that. It was kind of a demi god concept. True, many beginners in a hi tech field think like that. But as they move on they start respecting other specialists when they call them for referral for an issue in a different field of expertise. This is when the concept of 'i can also prescribe this and do this' diminishes.
Now that i start int med to move on to neuro, i realize that the job of internist is far from easy. Internists know much more than subspecialists on the wide spectrum of drugs prescribed, their adverse effects and interactions and also recognizing the early features of certain diseases clinically before someone from a non related field does.
If someone asked me about Dilantin(phenytoin), i could speak volumes about it. But if you ask me about ACE inhibitors, my knowledge was limited. But internists know about it and many other things. I eventually admired certain attendings who also taught residents dignity and respect for generalists and other specialists. There was a post op parasagittal meningioma with seizures we found difficult to control. Repeat CTs showed no hematoma or hydrocephalus. As nsurg residents our ego was preventing us from asking neurology referral. Our nsurg prof told us to do it. The neurology team evaluated and worked up the epilepsy and seizures were controlled.
There was a diabetic pt with brain tumor posted for surgery receiving dexamethasone to keep ICP in check. The blood sugar levels were high and we knew it was due to dexa, but how to modfiy antidiabetic drugs. All of us read about OHA and insulin preparations, but which to give and how much. So referred to an internist and it was done and everything was perfect.
Now i have a profound respect for internists (generalists) and their work. Most specialists cannot deal with many issues.
If i were asked this question, i would say- Sure i can prescribe, but i cannot use it to the patients benefit. By the way how much dose should i prescribe !!!!
