I don't like to see a doctor when I am sick. So I usually go to a pharmacy to buy some medications based on my symptoms. But I am concerned about the side effects of the medications because a certain medication is so comprehensive. For example, any cold pills cover fever, cough, sore throat, and runny nose. Sometimes I have to the over round pills even though I have only fever and sore throat. That's why there are a few advantages of prescribed medicine.
