That's what the doctor does ~ not the drug.
This business of leaping to the conclusion the drug had an adverse effect but the doctor is innocent (he's just standing there scratching his head dumbfounded by it all) is like arguing that guns leap off tables and shoot people!
Do your own research on the drug. I could spend days referring you to lawsuits and studies that justify my point. I hope it doesn’t affect a love one of yours like it did mine.
