24、ere is no such thing. There is always 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, whi
25、le others are able to cause death. 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 v
26、ery bothersome, you may decide that 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 reg
27、ional clergyman in Macon, Georgia, 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 t

29、 doctor, weighed the risks versus 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.

30、e drug works. It eases the pain.“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 co
31、lor changed? If so, call 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
32、are taking a drug in the 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
33、dose of a drug, while 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
34、in trials of drugs, yet 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.
35、 Even if it makes you 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 a
36、n expert consultant 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
37、theres been a label 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
38、more information, 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
39、take your pills 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 antihypertensiv
40、e 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 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 thei
