I have no idea what current practice is, but back then we used reference books. Knowing how to interpret the reference books -- that's what you do the degree and postgraduate training for. (And the commonest stuff you learned to spot straight off the bat.) One problem is that you need to be able to talk to/see the patient yourself. There's stuff that won't be in their medical records -- if they eat lots of spinach or drink grapefruit juice, for example. (Both of which have nasty side-effects when combined with various medications.) Or ask them how/when they take their meds. (A surprising number of patients misunderstand their prescriptions ...)
