I enjoyed reading your post. I use some apps to double check medication side effects, contraindications, appropriate dosage and etc. Sometimes our nursing resident or caregiver brings a pill and ask what is this? I look at its shape, color and the code numbers and check it with the pill identifier. It is good to have a portable reference handy, really helpful. The free version of Epocrates Rx is a great toll but if you want a comprehensive coverage you need to pay for the full version (You will not be able to see if herbal medications interact with the free version). I have tried Micromedex, Medscape Mobile and RxDrugs too, but I think the best one is Epocrates
