Six of the Biggest Placebo Scams at Your Drugstore

We call a product “snake oil” if it doesn’t do what its seller claims.  This can be said of several products on shelves at your local drugstore–none of which are based on credible evidence, and all of which rely on the placebo effect.

The funny thing is that real snake oil—oil derived from the Chinese water snake— is actually much more evidence-based than any of these products.  Genuine snake oil contains more EPA Omega 3 fatty acids than salmon, and there’s plenty of decent evidence backing up the benefits of Omega 3s.  So if you can find real snake oil (you might have to go to China), buy it. 

If you see any of the products below, not only should you not buy them, but make sure people who you like enough to save from getting scammed don’t fall for them either. 

[Brief preamble on the placebo effect: Yes, I know that the placebo effect can produce “real” results if the person using the product believes it will work. But those effects are generally short lived, and the core problem will remain untreated. What I’m focusing on in this post are products that are marketed as doing something without (non-placebo) medical evidence supporting the claim.]

Homeopathic Allergy Medication

The idea behind these products is that repeated exposure to allergens in small doses builds resistance.  The formulations contain micro doses of pollens, dust, mold, and the rest of what us allergy sufferers avoid at all costs.

The theory is sound. People who receive allergy shots (as I did for about 20 years) are getting dosed with the stuff they are allergic to. An immune response follows, and over time the body can (but often does not) become immune to the allergens.  This didn’t work for me, but I know people who it has worked for, so I’m not knocking it. 

But the crucial difference between medical allergy therapy and homeopathic allergy therapy, and what makes the latter ineffective, is how the dose is introduced into the body. Allergy shots go directly into the blood stream. Homeopathic allergy products are taken orally, and most of the ingredients never make it beyond your stomach acid. What little does get through is too diluted to have the intended effect.  The upshot is that sellers of homeopathic allergy meds are relying on a medically sound theory to sell their product, even though the product does not work the same way—or at all.

Head On

Headache?  Just roll a little Head On across your forehead and get ready for sweet relief.  Everything about this product screamed “fake!” from the start and yet millions of people bought it thinking the mystery balm would somehow penetrate their skull and neutralize the ouchy thing in their head.  And if that doesn’t do the trick, there’s always extra strength Head On, brimming with extra strong mystery brain balm.

Thankfully, legal pressure forced the makers of this ridiculous product to stop advertising that it cures headaches, but if you’re a true believer you can still buy it for about 10 bucks a tube.  But, don’t. 

Magnet Therapy

This one goes under several brand names, so I’ll have to generalize: any product claiming its magnets will cure, relieve, manage, reverse, massage, etc. is a scam.  I don’t care if the product makers guarantee results. What they’re relying on is that your belief in the product will be strengthened by the alleged guarantee, which reinforces the placebo effect.  Magnet therapy products are also expensive, another placebo reinforcing factor. 

There is no credible evidence supporting any of the medical claims for magnet therapy.  The studies that are generally cited by proponents are small, inconclusive pilot studies that were never replicated. Every other major study of magnets has shown that they do precisely nothing. The original lie that launched the magnet therapy industry was made by a doctor in the early 1970s, who swore his magnets could cure cancer—an obnoxiously fraudulent claim that was never proven, and never will be.  It’s a scam.

Phenylephrine

Most people remember the days when you could walk into a drugstore, grab a box of decongestant tablets off the shelf and buy them without feeling like a criminal. But meth heads were buying up so much of the cold meds containing pseudoephedrine, a key ingredient in making crystal meth, that the once cheap and accessible decongestants became a controlled substance behind the counter (via the Combat Methamphetamine Epidemic Act of 2005).  You can still buy them in many stores, but it’s a hassle.

The replacement for pseudoephedrine was phenylephrine, an active ingredient marketed as equally effective as pseudoephedrine. Just one problem with that claim—it’s not, and it may not be effective at all.  Studies have shown that only about 38% of phenylephrine is bioavailable once the med hits your stomach acid.  At the standard 10 mg dose, that’s a tiny amount of the substance left for absorption. Multiple studies have shown that the dose is no more effective than a placebo

The only notable exception was a study paid for by pharmaceutical company, and producer of products containing phenylephrine, GlaxoSmithKline, that claimed to show an effect superior to placebo. I think I’ll stick with the non-vested-interest studies and call this one a big, honking, runny-nosed placebo scam.         

Airborne

Airborne, the vitamin pill you drop in water and down like Alka Seltzer, was all the rage a couple years ago. Travelers especially loved it because it was marketed as an “immunity boost” against all those nasty germs other travelers are breathing on you in planes and airports.  All along it was a placebo scam, and the company was forced to pay a $23.3 million settlment for false advertising.  Below, the incomparable Dan Ariely talks about the death of his favorite placebo effect.

 

Diet Pills

Ephedra, the main ingredient in many diet pills, was banned by the FDA a few years ago after being linked to several deaths. The ban was lifted in December of last year, prompting a new round of industry marketing.  The reality, however, is that only one company is currently manufacturing genuine ephedra products. All the rest are either selling ephedra substitutes, fake ephedra, and/or scrambling to retool their manufacturing process, which they changed back when the drug was banned.

People frequently do lose weight on ephedra; the reason is twofold: one, the ingredient revs their metabolism, burning more calories, and the products also contain huge doses of caffeine adding to the effect.  This is dangerous. Even if it does not kill you, forcing your body to artificially accelerate for extended periods can damage blood vessels, not to mention skyrocket stress and anxiety levels.  And if you happen to have a heart condition, even one you don’t know about yet, much worse could happen.

The other reason people lose weight is because they pair the pills with increased activity.  This is partly due to the metabolism effect, and partly placebo effect (i.e., “the pill is helping me workout more”). 

So the concluding remark is that any diet pills on the market now that contain an ephedra substitute are placebo scams, period.  When ephedra becomes widely available again, it will be just as dangerous as it was before, and wisely avoided.

    Actually, 0 molecules of the active ingredients in homeopathic medicine will reach your stomach. In order to be considered homeopathic, the ingredients must be diluted in water way past Avogadro’s Limit which means there are none left at all.*

    I remember many years ago, an article in the Journal of Irreproducible Results on suggested names for placebo drugs. This was triggered at the time by a study that concluded that placebos weren’t all equal, and that they had to come up with some different types.

    The article is a dim memory, but I seem to remember Confabulase, and Noneatall as two candidate names. It seems that the modern market has done them much better. Now we have entire classes of drugs that may improve upon the placebo effect…

    “Noneatall” — that’s funny. Thanks for the comment jake!

    You dignify homeopathy too much by writing that “the theory is sound”. It’s not. Homeopathy’s theory is “like cures like” – that a substance that induces a condition can cure it if administered in small amounts. So if you suffer from nausea, an immense dilution of a nausea-causing substance will cure it. Resemblance to immunology is coincidental.

    Don’t forget big pharma. If they aren’t scamming you on price they are over-hyping products, pushing doctors to prescribe a product for use not cleared by the FDA, and fixing their own test results. The whole business is a scam. And why should we be surprised?
