Of course, plenty of M.D.'s do know which prescription and over-the-counter drugs are duds, dangers, or both. So we asked them, "Which medications would you skip?" Their list is your second opinion. If you're on any of these meds, talk to your doctor. Maybe he or she will finally open that big red book with all the dust on it.
Advair
It's asthma medicine ... that could make your asthma deadly. Advair contains the long-acting beta-agonist (LABA) salmeterol. A 2006 analysis of 19 trials, published in the Annals of Internal Medicine, found that regular use of LABAs can increase the severity of an asthma attack. Because salmeterol is more widely prescribed than other LABAs, the danger is greater — the researchers estimate that salmeterol may contribute to as many as 5,000 asthma-related deaths in the United States each year. In 2006, similarly disturbing findings from an earlier salmeterol study prompted the FDA to tag Advair with a "black box" warning — the agency's highest caution level.
Avandia
Diabetes is destructive enough on its own, but if you try to control it with rosiglitazone — better known by the brand name Avandia — you could be headed for a heart attack. Last September, a Journal of the American Medical Association (JAMA) study found that people who took rosiglitazone for at least a year increased their risk of heart failure or a heart attack by 109 percent and 42 percent, respectively, compared with those who took other oral diabetes medications or a placebo.
Celebrex
Ketek
Most bacteria in the lungs and sinuses don't stand a chance against Ketek, but you might not either. This antibiotic, which has traditionally been prescribed for respiratory-tract infections, carries a higher risk of severe liver side effects than similar antibiotics do. "Ketek can cause heart-rhythm problems, can lead to liver disease, and could interact poorly with other medications you may be taking," says Dr. Rodgers.
Prilosec and Nexium
Heartburn can be uncomfortable, but heart attacks can be fatal, which is why the FDA has investigated a suspected link between cardiac trouble and the acid-reflux remedies Prilosec and Nexium.
Visine Original
What possible harm to your peepers could come from these seemingly innocuous eyedrops? "Visine gets the red out, but it does so by shrinking blood vessels, just like Afrin shrinks the vessels in your nose," says Thomas Steinemann, M.D., a spokesman for the American Academy of Ophthalmology. Overuse of the active ingredient tetrahydrozoline can perpetuate the vessel dilating-and-constricting cycle and may cause even more redness.
Pseudoephedrine
Forget that this decongestant can be turned into methamphetamine. People with heart disease or hypertension should watch out for any legitimate drug that contains pseudoephedrine. See, pseudoephedrine doesn't just constrict the blood vessels in your nose and sinuses; it can also raise blood pressure and heart rate, setting the stage for vascular catastrophe. Over the years, pseudoephedrine has been linked to heart attacks and strokes. "Pseudoephedrine can also worsen symptoms of benign prostate disease and glaucoma," says Dr. Rodgers.
