I'm surprised the AMA, insurance companies or the US government haven't built a simple website that compares the drugs used to treat various conditions to combat the problem of people switching drugs because they are new or are heavily advertised. While a layman can't be expected to fully understand the benefits/drawbacks/interactions of a drug in detail, it seems like it should be possible to have an easy to understand grid of positives, negatives, retail price, etc. that would make comparing say, the brand new bipolar drug to old generic lithium.
