2、 如何加强学生的网络道德教育On Improving Students Network Morality_（分数：106.00）_二、Part Reading Compr(总题数：1，分数：70.00)Worried about prescription drugs? How to weigh your risk?When the pain reliever Vioxx was withdrawn from the worldwide market last September after the announcement that it increased patients risk of

3、heart attacks and strokes, millions panicked. Suddenly, ads for the drug were replaced with ads looking for Vioxx “victims“. Not only did patients stop taking Vioxx but, doctors say, many people stopped taking their other medicines, too-sometimes putting their health at serious risk. The sometimes-s

4、ensationalized headlines didnt help. People wondered. Should I trust my doctors? Could what I thought would help me actually kill me? Is the drug safety system broken?Americans have somehow come to believe they should get the best medical care with the latest remedies with no side effects. But there

5、 is no drug that doesnt have side effects. Peter Corr, head of worldwide research and development for drug manufacturer Pfizer says, “As a society weexpect medicine to be perfect. There is no such thing. There is always a risk.“How You Can Make Informed DecisionsSince there is no such thing as a pil

So how should you and your doctor proceed?1. Weigh

7、 the risks and benefits of any drug.As a smart consumer you must decide whether a drug is “safe enough“ for you. The greater the benefit, the more risk you may be willing to take. If your illness is mild and not very bothersome, you may decide that any risk is too big and opt against taking any medi

8、cations at all. On the contrary, if your illness is serious or potentially life threatening, you may even be willing to try an experimental drug with greater risk for serious side effects.Zena McAdams, 59, a regional clergyman in Macon, Georgia, has lived with a condition that causes chronic pain fo

9、r many years. For a long time she took OTC ibuprofen (布洛芬，一种镇痛非处方药), “I mean lots of it,“ she says. In the spring of 2001, her doctor prescribed Vioxx. Taken only once a day, it was “remarkable,“ she says. “I took it every day till it was taken off the market.“After speaking to her doctor, she switc

10、hed to Celebrex last October. It was also effective in controlling the aches and pains associated with her condition-until she heard concerns that it, too, had serious potential side effects. She talked to her doctor, weighed the risks versus the benefits and decided that her quality of life was mos

11、t important. “There is always that nasty feeling about safety,“ she says, “but there is no reason to think that I have any heart problems. The benefits at this point in my life certainly outweigh the risks. The drug works. It eases the pain.“2. Be especially cautious about new drugs.New drugs are in

12、herently risky. So ff youre taking one, monitor yourself carefully. Have your eating and digestive habits changed? Are you feeling unusually tired or agitated? Have your breathing patterns or skin color changed? ff so, call your doctor immediately, who may tell you to stop taking the drug. How does

13、a consumer know that a drug is new? Ask your doctor or pharmacist (药剂师).If you have a choice between two or more equally effective drugs, choose the one with a longer track record of safety, If you are taking a drug in the same class as one that has been recalled, it is careful to ask your doctor ff

14、 that drug places you at greater risks.3. Know if youre in a high-risk group.Although scientists still dont know precisely why, certain individuals have bad reactions to a drug or to a particular dose of a drug, while others dont. Men metabolize (新陈代谢) drugs differently than women do, for example. B

15、e especially watchful if you are very young, very old or pregnant. Drugs usually arent tested on these groups. “I worry the most about the elderly,“ says Avorn. “They are vastly underrepresented in trials of drugs, yet they are the most likely to be taking the drugs when they are approved.“4. Ask th

16、e right questions.When you get a new prescription, never leave the doctors surgery without a clear understanding of why youre taking the drug, how to take it, and how youll know if its working. Even if it makes you a bit uncomfortable, ask You are responsible for your own health and safety. “If the

17、doctor doesnt want to answer questions, you should probably find another doctor,“ says Avorn.After your visit, if you still have questions, call or e-mail the doctor. Use your pharmacist as an expert consultant for any additional concerns you have about the drug or its side effects.You can ask the p

18、harmacist for the professional package insert for the drug, says Corr. Although its written for health care providers, it includes information on clinical trials and side effects. Also, if theres been a label change, with new information about the drug or any warnings, it will be part of the PPI (保险

19、证明). Or request more consumer-friendly information, which should tell you how to use the drug properly and warn of any precautions. You can also call the drug companys toll-free number for more information, or go to its web-site.5. Be informed, and follow directions carefully.Check that the pills yo

20、u receive are the correct ones. Errors crop up in the dispensing of medications: Its easy to confuse products with similar names (for example, Zantac and Xanax).Read the instructions and take your pills exactly as prescribed. Be alert for expiration dates, and stay attentive to recalls and warnings.

21、 Tell your doctor about any other medications you take, either prescribed or OTC (over the counter). Drug interactions can cause serious problems. For example, Posicor, an anti-hypertensive drug (治疗高血压的药), was taken off the market because it could cause blood pressure to drop sharply when used with

22、other heart medications. If you fill all your prescriptions at the same store, the pharmacist may be able to warn you of known interactions.It is vitally important that patients and their doctors provide feedback to manufacturers and regulators if they have any suspicion of a problem.
