I think they are vastly over-prescribed in this country, you can thank the immensely wealthy pharmaceutical companies for that. We shouldn't be loading people down with these drugs, we are at a point now where we are taking so many different medications it is almost impossible to know for sure their interactions.

In order to know if there are potentially dangerous drug interactions there would have had to have been a chronic toxicity study done on every drug's interaction with every other drug. Trust me, there hasn't been such research conducted.
