Pills.....

All drugs have potential side effects. Some people are more susceptible to side effects than others. The common aspirin also has dangerous side effects. Hell, even drinking too much water can kill you.

A good doctor will continually monitor a patient for side effects, efficacy, and blood level, depending on the drug. Some drugs do not work on some people; that is the reason a doctor might try numerous drugs or a combination of them to get the desired results.

The bottom line is that a patient does not need to take any medicine he does not want to take.
