the dangers of prescription are the charges you pay the chemist. sometimes you can get the same medicines over the counter at a cheaper price than the prescription charges. put a bit more simpler, you dont always get what you think you are getting. the trick is to ask the right questions, make sure the answers actually relate to the questions that need answering and then make a decision, remembering you may have to swallow it at the end of the day!
even if it is a bitter pill!
edit added - ok, i know its a convoluted answer so perhaps this may help - the doctor tells you need to take something/do something to deal with an issue. the doctor writes a prescription out detailing exactly what you need to do, however when you go to the chemist they tell you there is a 'cheaper' way of achieving the end result - who is wrong? the doctor for giving you a prescritpion in a detailed solution, the chemist for advising you of a different solution achievable at a lower cost or you for not seeking an alternative medicine?
is that better?
