How to weigh your risk? A When the pain reliever Vioxx was withdrawn from the worldwide mar

22、ket last September after the announcement that it increased patients risk of 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 m

23、edicines, too sometimes putting their health at serious risk. The sometimes-sensationalized 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? B Americans have somehow come to believe they should ge

24、t the best medical care with the latest remedies with no side effects. But there is no drug that doesnt have side effects. Peter Corr, head of worldwide research and development for drug manufacturer Pfizer says, “As a society we expect medicine to be perfect. There is no such thing. There is always

25、 a risk.“ C Since there is no such thing as a pill that is completely safe, including aspirin, consumers have to accept the dichotomy (一分为二 ) that the same medicines that extend and enhance our lives may hurt us: some of them may merely have minor side effects, while others are able to cause death.

26、So how should you and your doctor proceed? 1. Weigh the risks and benefits of any drug. D 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 th

27、at any risk is too big and opt against taking any medications 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. E Zena McAdams, 59, a regional clergyman in Macon, Georgi

28、a, has lived with a condition that causes chronic pain for 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 t

29、aken off the market.“ F After speaking to her doctor, she switched 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 v

30、ersus the benefits and decided that her quality of life was most 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 p

31、ain.“ 2. Be especially cautious about new drugs. G New drugs are inherently risky. So if youre taking one, monitor yourself carefully. Have your eating and digestive habits changed? Are you feeling unusually tired or agitated (焦虑不安的 )? Have your breathing patterns or skin color changed? If so, call

32、your doctor immediately, who may tell you to stop taking the drug. How does 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

33、 same class as one that has been recalled, it is careful to ask your doctor if that drug places you at greater risks. 3. Know if youre in a high-risk group. H Although scientists still dont know precisely why, certain individuals have bad reactions to a drug or to a particular dose of a drug, while

34、others dont. Men metabolize (新陈代谢 ) drugs differently than women do, for example. Be 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 under-represented in trials of drugs, y

35、et they are the most likely to be taking the drugs when they are approved.“ 4. Ask the right questions. I 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 y

36、ou a bit uncomfortable, ask. You are responsible for your own health and safety. “If the 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

37、 for any additional concerns you have about the drug or its side effects. J You can ask the pharmacist 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 labe

38、l change, with new information about the drug or any warnings, it will be part of the PPI (保险证明 ). 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,

39、 or go to its website. 5. Be informed, and follow directions carefully. K Check that the pills you 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

40、 exactly as prescribed. Be alert for expiration dates, and stay attentive to recalls and warnings. 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 antihypertensive drug (治疗高血压的药

41、 ), was taken off the market because it could cause blood pressure to drop sharply when used with other heart medications. If you fill all your prescriptions at the same store, the pharmacist may be able to warn you of known interactions. L It is vitally important that patients and their doctors pro

42、vide feedback to manufacturers and regulators if they have any suspicion of a problem. Then these signals will be known and can be analyzed to see if they are more widespread, which could save lives. 37 Among drugs with equal effect, you should choose the one with a longer safety record. 38 Informat

43、ion on clinical trials and side effects of a drug can be found in its professional package insert. 39 When Posicor is used with other heart medications, it may lead to sharp drop of blood pressure. 40 Patients with a minor illness are the least likely to try drugs with serious side effects. 41 If pa

44、tients and doctors can provide appropriate feedback to drug manufacturers, many lives could be saved. 42 Avorn worries about the elderly most because they usually arent included in the trials of new drugs. 43 Drugs with similar names may result in errors of medication dispensing. 44 According to Pet

45、er Corr, every drug has certain kind of side effects. 45 For many years, Zena McAdams had to take medicines to control chronic pain. 46 It is suggested that we should change the doctor if he/she doesnt want to answer the questions about drug usage. Section C 46 Girls think they are cleverer, more su

46、ccessful and harder working than boys from as young as four, a study has found. Boys come round to this view by the age of seven or eight and assume that girls will outperform them at school and behave better in lessons, research from the University of Kent shows. The study Gender Expectations and S

47、tereotype Threat argues that teachers have lower expectations of boys than of girls and this belief fulfils itself throughout primary and secondary school. Girls performance at school may be boosted by what they perceive to be their teachers belief that they will achieve higher results and be more c

48、onscientious (勤奋的 ) than boys, the academics claim. Boys may underachieve because they pick up on teachers assumptions that they will obtain lower results than girls and have less drive. “By seven or eight years old, children of both genders believe that boys are less focused, able and successful th

49、an girls and think that adults endorse (认可 ) this stereotype,“ the academic Bonny Hartley said. “There are signs that these expectations have the potential to become self-fulfilling in influencing childrens actual conduct and achievement.“ Hartley said that while it was unacceptable to divide classes by the race of their pupils, this was not the case for gender. “In this way, it is widely acceptable to pitch the boys against the girls or harmlessly div
