Very informative and helps us save a lot of money on prescription drugs. Instead of having a doctor initially prescribe a 30 day supply of a new medication; I always ask for samples or an rx for 10 pills. I check the medication on Web MD before deciding whether I should take it or not. Why spend the money on a prescription if I'm not going to be taking it or it may give me an adverse reaction. The fine details about any possible illness is very informative. Things that I might forget to ask the doctor can always be found on Web MD
