The answer would be D, the one closest to "all of the above".
The correct option is B.
According to CDC, adverse drug events cause more than 700,000 emergency hospital visits annually in USA. There are several reasons for these adverse drug events and one of them is the use of non-prescribed drugs by individuals. Over-the- counter- drugs are those drugs that people can buy without any doctor prescribing the drugs for them. Using drugs in this manner causes serious problems which are usually life threatening.
