Yes. Not all pharmacies offer the full array of vaccines recommended for overseas travel. But if one in your area provides that service, it's certainly a safe, convenient way to get the immunizations you need to help you stay healthy on your trip.

Testosterone drugs such as Androgel 1.62% and Axiron increase the risk of heart attacks, strokes, and other cardiovascular events in men who take the drugs. Children accidentally exposed to testosterone can experience early puberty, and women who touch the stuff can experience acne and the growth of body hair. Need another reason to steer clear of the drugs? Consider this: The gels are flammable.

Not from your vet. They sharply mark up their drug prices, and tack on a $5 to $15 dispensing fee, according to the American Animal Hospital Association. For many pet meds, a better bet is your local pharmacy.

Not if the screening device scans your heel to capture your bone density measurement, instead of the lower spine or hip. Bone density measurements help determine if you have osteoporosis. But heel scans can be inaccurate, say our medical consultants. The problem is that "normal" results could provide a false sense of security. For a better assessment, and to help determine whether you even need the test at all, discuss with your doctor.

Think a pill that packs two cholesterol-lowering drugs in one potent package is a good idea? The Food and Drug Administration thinks so. It recently approved the combination of the popular statin drug Lipitor (atorvastatin) with another medication called Zetia (ezetimbe). But our medical advisers say the new product, Liptruzet, is too risky and too expensive.

Emergency-room visits stemming from Ambien, Edluar, Zolpimist, and other insomnia drugs containing zolpidem have more than tripled in recent years, according to a new report.

Superstorm Sandy devastated not just homes and property, but people's ability to get needed health care, too. A quarter of the people in our survey of online subscribers in Connecticut, New Jersey, and New York said Sandy caused medical hardships, especially with getting prescription drugs by mail and closed pharmacies.

If you've ever had trouble affording your medications and wanted to call your doctor on it, here's some encouraging news: Doctors aren't pleased about the prices either. Denouncing "profiteering" by pharmaceutical companies, more than 100 cancer doctors and researchers specializing in treating the blood cancer chronic myeloid leukemia (CML) argued the pressing need to lower cancer drug prices in a paper published last week in the journal Blood. And the doctors noted that the costs of prescription drugs, combined with medical illnesses, are the "the single most frequent cause of personal bankruptcies."

About a year after they expire. In most cases, prescription-drug expiration dates are one year to five years from the date they were made. But some pills can actually keep for a decade or even longer, research suggests. "Except for tetracycline, which can become toxic and cause kidney problems, expired drugs generally don't appear to cause harm," says Consumer Reports' chief medical advisor, Marvin M. Lipman, M.D. "But they do become less potent over time."

Walmart and Target win out over drugstore chains like Rite-Aid, CVS, and Walgreens, as well as supermarkets, on prices for dozens of common, brand-name and generic over-the-counter drugs, according to our team of Secret Shoppers.

We're barely a week into Spring and already pollen counts in some parts of the U.S. are on the rise, causing sheer misery in the form of runny noses, itchy, watery eyes, and sneezing for nearly 60 million seasonal allergy sufferers. If you're one of them, you know that getting relief, short of locking yourself way for the next three months, can be difficult. But it's not impossible.

Scratch headaches off the list of excuses for avoiding sex. Surprisingly, German researchers recently found that among 800 migraine sufferers, two-thirds of those who had sex during their migraines reported that their headache pain felt better afterward. Most of the rest, however, said the pain got worse. We'll let you be the judge of that. In the meantime, we stand by another, better studied option to help relieve migraines: the generic form of Imitrex, or sumatriptan.

More kids, with the blessing of their doctors and parents, take drugs to improve their attention, focus, and memory, even when they don't have attention deficit hyperactivity disorder (ADHD). But that practice is "not justifiable," according to new recommendations from the American Academy of Neurology.

The hour of sleep you'll lose Sunday morning when your clock springs forward might do more than just make you cranky. Some research suggests it translates into more car crashes and even heart attacks on Monday morning, thanks to worsened sleep deprivation. But a few simple steps might help smooth the transition.

Sleep problems keeping you up at night? Exercise, no matter the level or time of day, might help, according to a poll by the National Sleep Foundation released this week. It found that people who exercise, whether light or vigorous, early in the day or right before bed, sleep better than people who don't exercise at all.
