4、eased 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 hut, doctors say, many people stopped taking their other medicines, too-sometimes putting their health at seriou

5、s 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? Americans have somehow come to believe they should get the best medical care, with the lat- est remedies with

6、 no side effects. But there is no drug that doesnt have side effects. Peter Con, 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 a risk.“ How You Can Make Informed Decisions Since th

7、ere 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. So how should you

8、and your doctor proceed? 1. Weigh 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 b

9、ig 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. Zena McAdams, 59, a regional clergyman in Macon, Georgia, has lived with a co

10、ndition 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 taken off the market.“ Af

11、ter 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 versus the benefits and dec

12、ided 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 pain.“ 2. Be especially cau

13、tions about new drugs. 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? Have your breathing patterns or skin color changed? If so, call your doctor immediately, who may tell

14、 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 same class as one that has been reca

15、lled, it is careful to ask your doctor if that drug places you at greater risks. 3. Know ff 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 ) dru

16、gs 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, yet they are the most likely to be takin

17、g the drugs when they are approved.“ 4. Ask the 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 resp

18、onsible 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 email the doctor. Use your pharmacist as an expert consultant for any additional concerns you have abou

19、t the drug or its side effects. You can ask the pharmacist for the professional package insert (插页 ) 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 t

21、, and follow directions carefully.

Read the instructions and take your pills exactly as prescribed. Be alert for ex

22、piration 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 anti-hypertensive drug (治疗高血压的药 ), was taken off the market because i

23、t 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.
