Speaking as a nurse in response to your questions for the other poster........sometimes two meds are needed to achieve optimum results. Several examples would be say when the doctor prescribes an oral diabetic medication in addition to having the patient use insulin. The oral diabetic med helps the patient so that he requires less insulin. Another would be using a decongestant along with a pain med for sinus headaches. The decongestant alone is not totally effective but taken together they relieve the congestion as well as the headache. With ADD one med may help with one set up of symptoms but not with some of the others so they add second med to help with the other symptoms. Some people get good control with just one medication while others need more than one to help. Remember all meds work and effect everyone differently.
