A very strong case can be made for Doctors not even prescribing specific drugs. Even the best docs don't really know the drugs that well, but pharmacists do. Doctors should do the diagnosing of the issue(s) and if they wish to use a pharmaceutical treatment send the information to the pharmacist and let them consult with the patient and choose the appropriate drug(s) and dosage. This is especially important when dealing with multiple medications from multiple specialists. Pharmacists are by far the most under-appreciated medical professionals.
