Americans spend upwards of
$20 billion each year on unproven medical treatments. Sixty percent
of those who try untested therapies are over 65 and spend an
estimated $10 billion on them, according to a 1984 House Subcommitte
on Health and Long-Term Care report, "Quackery: A $10 Billion
Scandal."
Approximately 80 percent
of older Americans have one or more chronic health problems,
according to John Renner, M.D., a Kansas City-based champion
of quality health care for the elderly. He says their pain and
disability lead to despair, making them excellent targets for
deception.
"Despite disappointments
with promised cures, they continue to hold out hope that next
quick `cure' will work," says anti-fraud activist Stephen
Barrett, M.D.
Frightened of losing a parent
or grandparent, family members, too encourage them to "try
everything, especially unproven remedies, according to Barrie
R. Cassileth, Ph.D., writing in CA--A Cancer Journal for Clinicians.
And, indeed, sometimes people
get better when using unproven treatments. But because these
therapies have not passed scientific muster, it is impossible
to know if improvement is associated with the treatment, represents
spontaneous change, or is due to the "placebo" effect.
(A placebo is an inactive substance with no known therapeutic
value. The "placebo effect" is the phenomenon of people
getting better while taking an inactive substance they believe
to be therapeutic.)
"It's important to remember,"
says Barrett, "that many conditions get better on their
own, or appear to get better if we believe they will."
What's the Danger?
Taking a chance on unproven
treatments is not simply useless, it is often dangerous, according
to the Food and Drug Administration, which divides such products
into two categories: direct health hazards and indirect health
hazards.
Direct health hazards are
likely to cause serious injuries. For example, muscle stimulators,
promoted falsely as muscle toners, carry a risk of severe electric
shock.
Indirectly harmful products
are those that cause people to delay or reject proven remedies,
according to FDA. For example, if cancer patients reject proven
therapies in favor of unproven ones, their disease may advance
beyond the point where proven therapies can help.
All types of unproven therapies
can be economically harmful, often draining precious dollars
from older Americans' limited resources.
FDA's Health Fraud Staff,
in its Center for Drug Evaluation and Research, investigates
any product for which a disease claim is made. Joel Aronson,
director of the health Fraud Staff, points out that once a manufacturer
claims a product can treat or prevent a disease or condition,
"whether that product is bottled water or an herb, it is
considered a drug and falls under FDA jurisdiction." A product
is also considered a drug if it claims to alter the structure
or function of the body.
FDA's Center for Food Safety
and Applied Nutrition becomes involved with issues such as health
claims for herbs, vitamins, and other dietary supplements (see
"Dietary Supplements: Making Sure Hype Doesn't Overwhelm
Science" in the November 1993 FDA Consumer). For a reprint

FDA's Promotion and Advertising
Staff, in its Center for Devices and Radiological Health, investigates
health and disease claims made about devices. Byron Tart, acting
director, explains that such devices fall into two main categories:
devices approved for some medical use but promoted for an unapproved
use, and devices not approved for any medical use at all.
Targeting Older Americans
Commonly, unproven products
are pushed zealously on the elderly. Promoters often claim their
products prevent aging and such conditions as arthritis, Alzheimer's
disease, heart disease, and impotence.
According to the National
Institute on Aging, however, "while a healthy lifestyle
will help delay many of the conditions associated with aging
processes, no preparation or device can stop aging." The
1984 House Subcommittee report estimated that people spent at
least $2 billion per year on anti-aging remedies. Some anti-aging
products are also promoted to either prevent or treat Alzheimer's
disease.
According to JoAnn McConnell,
Ph.D., of the Alzheimer's Association, "so-called new `cures'
for Alzheimer's surface constantly."
But there are no cures, which
may cause Alzheimer's patients and their families to be susceptible
to products holding out false hope.
There is, however, one approved
treatment for Alzheimer's disease: the drug Cognex (tacrine hydrochloride),
which was approved in September of 1993 specifically to treat
the symptoms of Alzheimer's disease. "It is not a cure for
Alzheimer's disease," says FDA Commissioner David A. Kessler,
M.D., "but it provides some relief for patients and their
families."
Particularly susceptible
to deception are the 37 million Americans--many of them over
65--who have arthritis. One reason is that arthritis symptoms
come and go, causing people to associate their spontaneous relief
with a new "remedy." The Arthritis Foundation says
that older Americans spend an estimated $2 billion annually for
unproven arthritis remedies.
A Closer Look
Here's a closer look at some
unproven therapies promoted for a variety of ills common in older
people:
Cellular Therapy promoters claim an extract from animal
hearts can strengthen human hearts, eye extracts can cure eye
disease, and so on. FDA says there are no scientific studies
demonstrating the safety and effectiveness of cellular therapy
for any medical purpose and warns of health problems, including
severe allergic reactions and death.
Chaparral is an herb used in teas, capsules and tablets
that promoters purport delays aging, cleanses the blood, and
treats cancer. In early 1993, FDA warned consumers not to use
it because it had caused serious liver and kidney troubles. Most
manufacturers voluntarily withheld chaparral- containing products
from sale, and consumers are advised not to use remaining products.
Coenzyme Q-10, a synthetically produced version of
a naturally occurring enzyme, is promoted to slow aging by enhancing
the immune system. Not only is there no proven benefit, but it
may be dangerous for people with poor circulation, according
to Edward L Schneider, M.D., of the National Institute on Aging.
Overall, there is no evidence that "boosting" the immune
system delays aging, nor is there any evidence that it's possible
to do so, according to Schneider.
DHEA (dehydroepiandrosterone) is a naturally occurring
chemical. Because levels decline with aging, some scientists
speculate it may play some role in aging processes. But there
is not proof that DHEA delays aging, according to Schneider.
DMSO, or dimeltyl sulfoxide, is a solvent similar to
turpentine promoted for arthritis relief. In a sterile form called
Rimso-50, it is approved by FDA for treating a rare bladder condition
called interstitial cystitis. For this approved use, it is instilled
into the bladder for short times (20 to 30 minutes). This is
the only approved human use. There are no controlled studies
demonstrating its safety and effectiveness in relieving swollen,
inflames arthritis joins, and in an impure form it can harbor
bacterial toxins that can enter the bloodstream even when applied
topically. It is one of the few compounds rapidly absorbed through
the skin. It can be especially dangerous if used as an enema,
as recommended by its promoters.
Electrical Stimulators are approved by FDA when prescribed
by physicians for various conditions, including after-stroke
therapy. However, FDA has not approved them for wrinkle removal
and face lifts.
Geranium, an inorganic, nonessential element sold as
a dietary supplement. Promoters claim it prevents and treats
Alzheimer's, and advise users to apply bandage wraps with it
to treat arthritis and headaches. Not only is geranium ineffective,
but is has caused serious irreversible kidney damage and death,
according to FDA.
Gerovital-H3, originating in Romania more than 30 years
ago, was brought here illegally and sold as a cure for arthritis,
atherosclerosis, angina pectoris, hypertension, deafness, Parkinson's
disease, depression, diabetes, and impotence. One of its ingredients
is procaine hydrochloride, an anesthetic approved for dental
use. No health claims for Gerovital have been substantiated,
and FDA considers it an unapproved new drug. It has caused low
blood pressure, respiratory difficulties, and convulsions in
some users.
Herbal Products are centuries-old, but mostly unproven,
"cures" for everything from constipation to anxiety.
They are available in various forms, including teas, capsules
and tablets. Some are potentially dangerous. Chamomile tea, for
example, can cause a severe allergic reaction in people allergic
to ragweed. Lobelia can cause vomiting, breathing problems, convulsions,
and even coma and death when used in large amounts; people with
heart disease are especially susceptible. Comfrey has caused
severe and even fatal liver disease. (See "Beware the Unknown
Brew: Herbal Teas and Toxicity" in the May 1991 FDA Consumer.)
Lecithin, a naturally occurring component of certain
body tissues, is touted for lowering cholesterol and treating
Alzheimer's disease. There's no proof that it's effective for
either one.
Low-Intensity Lasers are promoted to relieve arthritis
pain, but FDA has not approved them for this or any other use.
Hearing Aids
FDA is taking action to improve
the patient care of people who buy hearing aids. Though hearing
aids have significantly improved the quality of life for many
older Americans, the agency is concerned that some manufacturers
are making unsubstantiated claims about their devices and are
giving inaccurate portrayals of their devices' risks and benefits.
The agency last November
proposed changes to hearing aid regulations to require a hearing
assessment in all cases before a person is sold a hearing aid.
The regulation will also require that this assessment be done
by a qualified health professional licensed by the state. A public
hearing on the proposal was held Dec. 6 and 7 near FDA headquarters
in Rockville, Md.
Although a 1977 regulation
restricts hearing aid sales to people who have had a hearing
evaluation by a doctor within six months, FDA Commissioner Kessler
pointed out that the "regulation also included a provision
allowing fully informed adult patients to waive the medical examination."
Kessler said this waiver has been "overused and misrepresented."
Before proposing the regulation
changes, FDA reviewed promotional materials for a number of hearing
aids and found that several manufacturers were making unsubstantiated
and misleading claims that created unrealistic expectations about
the performance of the devices. In addition, the materials failed
to disclose significant information and did not accurately disclose
the device's potential risks and benefits.
At press time, FDA was reviewing
public comments on the proposed regulation changes.

Magnetism: Pressure dots with tiny magnets affixed
to adhesive strips that are worn over the arthritic area are
promoted for curing arthritis; a magnet in men's briefs is purported
to cure impotence; and a magnet used a suppository is promoted
for curing hemorrhoids. There is no scientific basis for any
of these claims.
Retin-A has been approved by FDA as a topical treatment
for acne. The agency, however, has not determined whether it
is safe and effective as a wrinkle remover.
RIFE Generator promoters claim that they can insert
a person's photograph into their device and diagnose medical
conditions. FDA has not approved the marketing of this device,
nor is there any scientific basis for this claim.
RNA, or ribonucleic acid, a natural body chemical that
carries genetic information, is a common ingredient in anti-
aging compounds and is also promoted for Alzheimer's. Promoters
claim it rejuvenates old cells, improves memory, and prevents
wrinkling. But there have been no controlled scientific studies
to back up these claims.
Superoxide Dismutase (SOD) is a normal body chemical
that is promoted as being able to slow aging and treat Alzheimer's
disease. According to the National Institute on Aging's Schneider,
writing in the New England Journal of Medicine, some studies
have shown higher tissue levels of SOD in longer-living species.
A survey of a large number of different animal species revealed,
in fact, that the longest- lived species, human beings, had the
highest tissue levels of superoxide dismutase. But there is no
evidence that SOD works to delay aging or prolong life, nor is
there any evidence that taking SOD tablets raises blood or tissue
levels of SOD.
Avoiding Fraud
According to FDA, these red
flags should make you think twice about remedies not prescribed
by your doctor:
* celebrity endorsements
* inadequate labeling (a legitimate non-prescription medication
is labeled with indications for use, as well as how to use it
and when to seek medical help)
* claims that the product works by a secret formula
* promotion of the treatment only in the back pages of magazines,
over the phone, by direct mail, in newspaper ads in the format
of new stories, or 30-minute commercials in talk show format.
The Arthritis Foundation
says the following claims are also warning signs that a "cure"
has but questionable therapeutic value:
* It's effective for a wide range of disorders, such as cancer,
arthritis and sexual dysfuntion. ("But, say FDA's Aronson,
"don't misinterpret this a believe a product promoted for
only one disease is safe and effective.")
* It's all natural
* It's inexpensive and has no side effects.
* It works immediately and permanently, making a visit to the
doctor unnecessary.
Older Americans, along with
younger folks, should remember that falling victim to health
fraud is "not a matter of being weaker or foolish,"
says Renner. "It is a matter of being in pain or having
more than one chronic illness--or both."
Barrett offers a final word
of advise: "When you feel your physician isn't doing enough
to help, don't stray from scientific health care in a desperate
attempt to find a solution." Instead, ask your physician
to provide a more detailed explanation or to refer you to another
doctor.
