Is Your Pharmacy Selling Snake Oil?

Pop quiz: The photo above was taken recently at a large pharmacy chain. One shelf features products that have been tested in clinical trials, shown to be effective, and approved for sale by the FDA. The other shelf promotes products that are, as obesity specialist Yoni Freedhoff, MD, puts it, “At best, yet-to-be-proven hope — and at worst, useless hogwash.”
Can you tell which is which?
OK, it’s pretty obvious when we phrase it that way. (The FDA-approved meds are on the top shelf.) But when you’re browsing the rows upon rows of boxes in the health aisles of your local pharmacy, the differences between evidence-based drugs and poorly researched supplements aren’t always so clear.
As Freedhoff argues in a recent post on his website, selling trendy, unproven, herbal or so-called “natural” remedies only a few feet away from the pharmacy counter gives them an air of credibility that may not be deserved. “People see pharmacies as both business and service, where their service is to provide healthy products to their customers,” Freedhoff tells Yahoo Health. Pharmacists are regularly reported to be among the most trusted health professionals, he adds. As a result, many people assume that the “natural” products available for purchase in the pharmacy section meet the approval of the pharmacist.
Most often, that assumption would be incorrect. “The pharmacists I know are mortified by the [non-evidence-based] products their pharmacies sell,” Freedhoff says, referring specifically to supplements and devices such as raspberry ketones pills and ionic technology bracelets, which have little to no research to support the benefits they advertise.

“Most of the stuff out there is a total waste of money at best, and can be outright dangerous at worst,” says weight-loss expert Charlie Seltzer, MD. “Supplements are confusing as it is, and most people, even really smart ones, do not have the knowledge to look at a package and know whether the claims are based on real science or just marketing hype,” Seltzer tells Yahoo Health.
Many hot natural products, such as the green coffee bean extract pills that are suddenly in every grocery checkout line, simply don’t have much research conducted on them. So we often don’t know the side effects these products could cause or how they react with other drugs.
That’s in stark contrast to the rigorous research that prescription and over-the-counter medications must undergo. In the U.S., pharmaceutical companies must show proof that medications are safe and effective before they can legally hit the market. But supplements don’t. Instead, the government relies on consumers to report serious adverse effects that may be due to supplement use, and only then reviews the product’s safety.

To make smart decisions about the dizzying array of options on pharmacy shelves, experts offer these tips:
Don’t assume that something is safe just because it claims to be natural. “Plenty of ‘natural’ mushrooms grow in my front yard that I wouldn’t want to eat,” Freedhoff quips.
Know that not all doctors and pharmacists are supplement experts. “Much of what we learned in medical school about supplements was incorrect anyway regarding efficacy and safety,” Seltzer says.
Before you take a controversial new herbal product, Seltzer recommends, talk with a health professional who specializes in the condition that you are trying to treat. He or she will have the expertise to let you know if the compound in question could possibly help your problem, and can offer alternate or additional solutions.
