A prescription is as personal as your name. It is designed for you alone. It is based on such factors as your age, weight, general health, allergies (过敏症), and other factors, as well as your illness.
Never take a prescription drug meant for another person, even if you think you have the same illness. Prescriptions aren't supposed to be traded around the family or neighborhood. Each prescription is intended for an individual. It is a violation of federal law to sell a prescription drug without a prescription.
Doctors and dentists are licensed by each state to prescribe drugs for human use. Doctors for veterinary (兽医的) medicine are licensed to prescribe drugs for animal use.
A licensed medical doctor must pass all examination m practice medicine in a certain state. Before doing this, he or she has probably completed at least two years of a premedical course, a four-year medical course, two years of internship (实习) or residency in a hospital, and perhaps an extra year or more of training in a specialty -- altogether at least eight years of medical training, possibly nine.
Don't take prescriptions written for you during a previous illness without first checking with your doctor. Your illness may not be the same as the previous one, even though you think it is. Also the drug may have lost strength. Only a doctor is qualified to advise you about continuing to take a medicine.
Why does the law require that some drugs be used under a doctor's prescription？

听力原文： Feeling stressed lately？ Has the doctor said he cannot find anything wrong with you？ Perhaps he sent you to a hospital, but all the fancy equipment there showed that there was'nothing wrong with you. Then consider this: you might be in a state of sub-health. Sub-health, also called the third state or gray state, is defined as a borderline state between health and disease. According to an investigation by the National Health Organization, over 45 percent of sub-healthy people are middle-aged or elderly. The percentage is even higher among people who work in management positions as well as students around exam-time, due to their heightened exposure to stress.
The key to preventing and recovering from sub-health, according to some medical experts, is to form. good living habits, alternate work with rest, exercise regularly, and take part in open air activities. As for meals, people are advised to eat less salt and sugar. They should eat more fresh vegetables, fruits, fish and so on because they are rich in nutritional elements--vitamins and trace elements-that are indispensable to the body.
Nutrition experts point out that it is not good to eat too much at one meal because it may cause unhealthy changes in your body. They also say that a balanced diet is very helpful in avoiding subhealth.
