All sorts of things can go wrong – the drugs can have bad side effects that no-one predicted. One of the reasons for animal testing is to try and catch any drugs that might be harmful but it doesn’t always work. That’s also why when medicines are first tested in people something called “dose escalation” is used. This means that you give the first people a small dose of the drug & if it doesn’t harm them you give the next people a bit more and then the next people a bit more… until the side effects are too bad and you stop increasing the dose.
