Even in the cold of a bacterial infection that required the use of antibiotics, must also be used by doctors to decide what to do, should not be used on its own. At the same time, the cold is a self healing disease, cold medicine almost only symptomatic. This makes the "cold does not take medicine" has become a fully viable option.
