An FDA Guide to Choosing Medical Treatments
by Isadora B. Stehlin
Medical treatments come in many shapes and sizes. There are "home
remedies" shared among families and friends. There are prescription
medicines, available only from a pharmacist, and only when ordered by a
physician. There are over-the-counter drugs that you can buy--almost
anywhere--without a doctor's order. Of growing interest and attention in
recent years are so-called alternative treatments, not yet approved for
sale because they are still undergoing scientific research to see if
they really are safe and effective. And, of course, there are those
"miracle" products sold through "back-of-the-magazine" ads and TV
infomercials.
How can you tell which of these may really help treat your medical
condition, and which will only make you worse off--financially,
physically, or both?
Many advocates of unproven treatments and cures contend that people
have the right to try whatever may offer them hope, even if others
believe the remedy is worthless. This argument is especially compelling
for people with AIDS or other life-threatening diseases with no known
cure.
Clinical Trials
Before gaining Food and Drug Administration marketing approval, new
drugs, biologics, and medical devices must be proven safe and effective
by controlled clinical trials.
In a clinical trial, results observed in patients getting the
treatment are compared with the results in similar patients receiving a
different treatment or placebo (inactive) treatment. Preferably, neither
patients nor researchers know who is receiving the therapy under study.
To FDA, it doesn't matter whether the product or treatment is
labeled alternative or falls under the auspices of mainstream American
medical practice. (Mainstream American medicine essentially includes the
practices and products the majority of medical doctors in this country
follow and use.) It must meet the agency's safety and effectiveness
criteria before being allowed on the market.
In addition, just because something is undergoing a clinical trial
doesn't mean it works or FDA considers it to be a proven therapy, says
Donald Pohl, of FDA's Office of AIDS and Special Health Issues. "You
can't jump to that conclusion," he says. A trial can fail to prove that
the product is effective, he explains. And that's not just true for
alternative products. Even when the major drug companies sponsor
clinical trials for mainstream products, only a small fraction are
proven safe and effective.
Many people with serious illnesses are unable to find a cure, or
even temporary relief, from the available mainstream treatments that
have been rigorously studied and proven safe and effective. For many
conditions, such as arthritis or even cancer, what's effective for one
patient may not help another.
Real Alternatives
"It is best not to abandon conventional therapy when there is a
known response [in the effectiveness of that therapy]," says Joseph
Jacobs, M.D., former director of the National Institutes of Health's
Office of Alternative Medicine, which was established in October 1992.
As an example he cites childhood leukemia, which has an 80 percent cure
rate with conventional therapy.
But what if conventional therapy holds little promise?
Many physicians believe it is not unreasonable for someone in the
last stages of an incurable cancer to try something unproven. But, for
example, if a woman with an early stage of breast cancer wanted to try
shark cartilage (an unproven treatment that may inhibit the growth of
cancer tumors, currently undergoing clinical trials), those same doctors
would probably say, "Don't do it," because there are so many effective
conventional treatments.
Jacobs warns that, "If an alternative practitioner does not want to
work with a regular doctor, then he's suspect."
Alternative medicine is often described as any medical practice or
intervention that:
* lacks sufficient documentation of its safety and effectiveness
against specific diseases and conditions
* is not generally taught in U.S. medical schools
* is not generally reimbursable by health insurance providers
According to a study in the Jan. 28, 1993, New England Journal of
Medicine, 1 in 3 patients used alternative therapy in 1990. More than 80
percent of those who use alternative therapies used conventional
medicine at the same time, but did not tell their doctors about the
alternative treatments. The study's authors concluded this lack of
communication between doctors and patients "is not in the best interest
of the patients, since the use of unconventional therapy, especially if
it is totally unsupervised, may be harmful." The study concluded that
medical doctors should ask their patients about any use of
unconventional treatment as part of a medical history.
Many doctors are interested in learning more about alternative
therapies, according to Brian Berman, M.D., a family practitioner with
the University of Maryland School of Medicine in Baltimore. Berman says
his own interest began when "I found that I wasn't getting all the
results that I would have liked with conventional medicine, especially
in patients with chronic diseases.
"What I've found at the University of Maryland is a healthy
skepticism among my colleagues, but a real willingness to collaborate.
We have a lot of people from different departments who are saying, let's
see how we can develop scientifically rigorous studies that are also
sensitive to the particular therapies that we're working with."
Anyone who wants to be treated with an alternative therapy should
try to do so through participation in a clinical trial. Clinical trials
are regulated by FDA and provide safeguards to protect patients, such as
monitoring of adverse reactions. In fact, FDA is interested in assisting
investigators who want to study alternative therapies under carefully
controlled clinical trials.
Some of the alternative therapies currently under study with grants
from NIH include:
* acupuncture to treat depression, attention-deficit hyperactivity
disorder, osteoarthritis, and postoperative dental pain
* hypnosis for chronic low back pain and accelerated fracture healing
* Ayurvedic herbals for Parkinson's disease. (Ayurvedic medicine is a
holistic system based on the belief that herbals, massage, and
other stress relievers help the body make its own natural drugs.)
* biofeedback for diabetes, low back pain, and face and mouth pain
caused by jaw disorders. (Biofeedback is the conscious control of
biological functions such as those of the heart and blood vessels
normally controlled involuntarily.)
* electric currents to treat tumors
* imagery for asthma and breast cancer. (With imagery, patients are
guided to see themselves in a different physical, emotional or
spiritual state. For example, patients might be guided to imagine
themselves in a state of vibrant health and the disease organisms
as weak and destructible.)
While these alternative therapies are the subject of scientifically
valid research, it's important to remember that at this time their
safety and effectiveness are still unproven.
Avoiding Fraud
FDA defines health fraud as the promotion, advertisement,
distribution, or sale of articles, intended for human or animal use,
that are represented as being effective to diagnose, prevent, cure,
treat, or mitigate disease (or other conditions), or provide a
beneficial effect on health, but which have not been scientifically
proven safe and effective for such purposes. Such practices may be
deliberately deceptive, or done without adequate knowledge or
understanding of the article.
Health fraud costs Americans an estimated $30 billion a year.
However, the costs are not just economic, according to John Renner,
M.D., a Kansas City-based champion of quality health care for the
elderly. "The hidden costs--death, disability--are unbelievable," he
says.
To combat health fraud, FDA established its National Health Fraud
Unit in 1988. The unit works with the National Association of Attorneys
General and the Association of Food and Drug Officials to coordinate
federal, state and local regulatory actions against specific health
frauds.
Regulatory actions may be necessary in many cases because products
that have not been shown to be safe and effective pose potential hazards
for consumers both directly and indirectly. The agency's priorities for
regulatory action depend on the situation; direct risks to health come
first.
Unproven products cause direct health hazards when their use
results in injuries or adverse reactions. For example, a medical device
called the InnerQuest Brain Wave Synchronizer was promoted to alter
brain waves and relieve stress. It consisted of an audio cassette and
eyeglasses that emitted sounds and flashing lights. It caused epileptic
seizures in some users. As a result of a court order requested by FDA,
78 cartons of the devices, valued at $200,000, were seized by U.S.
marshals and destroyed in June 1993.
Indirectly harmful products are those that do not themselves cause
injury, but may lead people to delay or reject proven remedies, possibly
worsening their condition. For example, if cancer patients reject proven
drug therapies in favor of unproven ones and the unproven ones turn out
not to work, their disease may advance beyond the point where proven
therapies can help.
"What you see out there is the promotion of products claiming to
cure or prevent AIDS, multiple sclerosis, cancer, and a list of other
diseases that goes on and on," says Joel Aronson, director of FDA's
Health Fraud Staff, in the agency's Center for Drug Evaluation and
Research. For example, he says, several skin cream products promise to
prevent transmission of HIV (the virus that causes AIDS) and herpes
viruses. They are promoted especially to health-care workers. Many of
the creams contain antibacterial ingredients but, "there is no
substantiation at all on whether or not [the skin creams] work" against
HIV, says Aronson. FDA has warned the manufacturers of these creams to
stop the misleading promotions.
People at Risk
Teenagers and the elderly are two prime targets for health fraud
promoters.
Teenagers concerned about their appearance and susceptible to peer
pressure may fall for such products as fraudulent diet pills,
breast developers, and muscle-building pills.
Older Americans may be especially vulnerable to health fraud
because approximately 80 percent of them have at least one chronic
health problem, according to Renner. Many of these problems, such as
arthritis, have no cure and, for some people, no effective treatment. He
says their pain and disability lead to despair, making them excellent
targets for deception.
Arthritis
Although there is no cure for arthritis, the symptoms may come and
go with no explanation. According to the Arthritis Foundation, "You may
think a new remedy worked because you took it when your symptoms were
going away."
Some commonly touted unproven treatments for arthritis are harmful,
according to the foundation, including snake venom and DMSO (or dimethyl
sulfoxide), an industrial solvent similar to turpentine. FDA has
approved a sterile form of DMSO called Rimso-50, which is administered
directly into the bladder for treatment of a rare bladder condition
called interstitial cystitis. However, the DMSO sold to arthritis
sufferers may contain bacterial toxins. DMSO is readily absorbed through
the skin into the bloodstream, and these toxins enter the bloodstream
along with it. It can be especially dangerous if used as an enema, as
some of its promoters recommend.
Treatments the foundation considers harmless but ineffective
include copper bracelets, mineral springs, and spas.
Cancer and AIDS
Cancer treatment is complicated because in some types of cancer
there are no symptoms, and in other types symptoms may disappear by
themselves, at least temporarily. Use of an unconventional treatment
coinciding with remission (lessening of symptoms) could be simply
coincidental. There's no way of knowing, without a controlled clinical
trial, what effect the treatment had on the outcome. The danger comes
when this false security causes patients to forgo approved treatment
that has shown real benefit.
Some unapproved cancer treatments not only have no proven benefits,
they have actually been proven dangerous. These include Laetrile, which
may cause cyanide poisoning and has been found ineffective in clinical
trials, and coffee enemas, which, when used excessively, have killed
patients.
Ozone generators, which produce a toxic form of oxygen gas, have
been touted as being able to cure AIDS. To date this is still unproven,
and FDA considers ozone to be an unapproved drug and these generators to
be unapproved medical devices. At least three deaths have been connected
to the use of these generators. Four British citizens were indicted in
1991 for selling fraudulent ozone generators in the United States. Two
of the defendants fled to Great Britain, but the other two pleaded
guilty and served time in U.S. federal prisons.
The bottom line in deciding whether a certain treatment you've read
or heard about might be right for you: Talk to your doctor. And keep in
mind the old adage: If it sounds too good to be true, it probably is.

How to Approach Alternative Therapies
The NIH Office of Alternative Medicine recommends the following
before getting involved in any alternative therapy:
* Obtain objective information about the therapy. Besides talking
with the person promoting the approach, speak with people who have
gone through the treatment--preferably both those who were treated
recently and those treated in the past. Ask about the advantages
and disadvantages, risks, side effects, costs, results, and over
what time span results can be expected.
* Inquire about the training and expertise of the person
administering the treatment (for example, certification).
* Consider the costs. Alternative treatments may not be reimbursable
by health insurance.
* Discuss all treatments with your primary care provider, who needs
this information in order to have a complete picture of your
treatment plan.
For everyone--consumers, physicians and other health-care
providers, and government regulators--FDA has the same advice when it
comes to weeding out the hopeless from the hopeful: Be open-minded, but
don't fall into the abyss of accepting anything at all. For there
are--as there have been for centuries--countless products that are
nothing more than fraud.
Tip-Offs to Rip-Offs
New health frauds pop up all the time, but the promoters usually
fall back on the same old cliches and tricks to gain your trust and get
your money. According to FDA, some red flags to watch out for include:
* claims the product works by a secret formula. (Legitimate
scientists share their knowledge so their peers can review their
data.)
* publicity only in the back pages of magazines, over the phone, by
direct mail, in newspaper ads in the format of news stories, or
30-minute commercials in talk show format. (Results of studies on
bona fide treatments are generally reported first in medical
journals.)
* claims the product is an amazing or miraculous breakthrough. (Real
medical breakthroughs are few and far between, and when they
happen, they're not touted as "amazing" or "miraculous" by any
responsible scientist or journalist.)
* promises of easy weight loss. (For most people, the only way to
lose weight is to eat less and exercise more.)
* promises of a quick, painless, guaranteed cure
* testimonials from satisfied customers. (These people may never have
had the disease the product is supposed to cure, may be paid
representatives, or may simply not exist. Often they're identified
only by initials or first names.)
