Most radiologists are creatures of habit without much thought going into the process. The expansive lists of things that people must discontinue because of theoretical risk due to a drug interaction demonstrates the technician rather than physician component of the performance of myelography. Neurontin is also on the list along with a hundred other commonly taken drugs, whose withdrawal may cause significant side effects. Sometimes calling them and discussing these issues reveal the reasons for the lack of weighing the risk/benefits of drug withdrawal, and usually it is because these were published by some academic institution as a cautionary document, but ultimately became codified as law in the small city hospital's radiology department.
