Message in a Bottle: Protect yourself from harm’s way
People across the country are struggling to cope with effects of an
adverse drug reaction, but we - and even they - don’t know it, says
Colleen Fuller, a Vancouver-based drug safety advocate.
The Canadian public simply does not realize the extent of the harm
being caused by drug side-effects, she says.
“People will say, ‘Oh, these are symptoms of the condition that’s
being treated, so it’s not really a symptom, it’s not a side-effect
of the drug,” says Fuller. She insists it’s a view encouraged by the
drug industry. “And I think that Health Canada doesn’t address these
misperceptions in the public adequately enough.”
Fuller, who is a diabetic, experienced severe drug side-effects
herself starting in 1995, when the animal-derived insulin she relied
on was taken off the market.
Left with no choice, she switched to a newer form of synthetic
insulin billed as more closely resembling human insulin. She found
the drug affected her ability to detect low blood sugar. Fuller
experienced seizures, lost weight and couldn’t concentrate. She
feared going to sleep in case she never woke up. She even slipped
into comas.
“People lose their ability to detect low blood sugar and so, for
example, I would be sitting here talking… as my blood sugar is
plummeting and in mid-sentence I would be on the floor in a coma,”
she says. “And that’s what was happening to me and it happened over
and over and over again.”
Fuller lived this way for five years. She was told repeatedly that
she was the only one having a bad reaction to the insulin. In fact,
thousands were. Eventually Canadian diabetics that couldn’t tolerate
the new insulin banded together to regain access to animal-based
insulin. The whole experience changed Fuller forever. It also nearly
destroyed her marriage.
Patients who suffer serious drug side-effects are often affected
emotionally and psychologically, as well as physically, she
stresses. Families break up under the strain and people lose their
homes when they can’t work anymore.
“When people go through these experiences, it’s like being in an
earthquake that never ends. You can’t grab onto anything, because
it’s shaking too.”
In 2003 Fuller helped start PharmaWatch, a non-profit consumer
group, to promote greater public involvement in drug safety. Fuller,
a health policy researcher by trade, steadfastly believes that
consumers have been shut out of the drug safety system. While Fuller
says there needs to be more consumer involvement and oversight,
Canadians can also step up their awareness of how to avoid
experiencing drug side-effects in the first place.
One of the key steps is to stop looking for a chemical solution to
every problem.
“We live in a culture where the idea of taking drugs is kind of a
lifestyle choice. We’ve drifted quite a ways away from the idea of
prescription drugs being only necessary in certain circumstances,”
says Fuller. “The drug industry likes to promote drugs as something
that are fun to do that will improve your life…and the public does
buy into that to some extent.”
Experts say patients must stop expecting to always get a
prescription when they visit their doctor. Always ask what other
choices are available, advises James McCormack, a professor with the
faculty of pharmaceutical sciences at the University of British
Columbia, “You should really be going in and saying ‘What non-drug
things should I do?’ The bottom line is: If I don’t do anything,
what will happen? And if I do this, what will happen, percentage
wise?”
Research has shown repeatedly that the public places far too much
faith in medicines, often grossly overestimating their benefits.
“Patients are not even in the ballpark. They’re not even playing the
same game,” says McCormack. “They laugh when I tell them the
benefits. They go, ‘You’ve got to be kidding me.’”
Physicians and patients also need to remember that newer is better
in cars and computers, but not necessarily medications. Sticking
with the tried and true may be cheaper, but more importantly safer.
Newer drugs are heavily promoted, but older medications are often
just as effective and have the benefit of being road-tested for
potential side-effects. Older drugs are also cheaper, which saves us
all money -whether through the public purse or by our private
insurance rates.
Barbara Martinez, who works for a drug benefits consulting firm in
Toronto, says patients and physicians must get out of this mindset.
“I want the newest car, and the newest VCR, we want the newest
thing,” she says. The public also thinks that all drugs are
completely safe, just because they’ve been approved by Health
Canada. But the real test of the drugs comes in the first few years
of use in the real world, says Martinez, who worked in the drug
industry for many years. “Just because Health Canada approved it, we
don’t know that it’s safe, so stop thinking that.”
“It’s amazing how the pharmaceutical industry has been able to
convince us that each new drug is incrementally better,” says Larry
Sasich, a consultant with the Washington, D.C.-based consumer group
Public Citizen. “There’s nothing in our drug approval standard that
requires a new drug to be therapeutically superior to an old drug
before it can come on the market.” Sasich adds that we don’t need
more drugs - we need better drugs, and the only way to determine which
drug is better is to do head-to-head studies.
Martinez says we also have to shake the idea that drugs are free if
we have a private plan; we pay for them, one way or another.
A shocking number of patients don’t take their prescriptions - which
experts suggest is due to side-effects. Canadian pharmacies accept
unused pills one week a year to encourage people to clean out their
medicine cabinets. The results are measured in tons, marvels
Martinez. “All of those pills were paid for by somebody, probably by
an employer.”
Martinez says she sees her clients’ drug costs going up 10% or 20%
every year. “And their employees are not getting better. We’re not
healthier. We’re just taking more drugs, that’s all.”
She says Canadians may not realize that insurance contracts are
renegotiated every year, and the cost is not based on all employees
insured by the company but by your colleagues. If one employee
spends a lot, it will come out of your pool. The end result is that
companies start cutting dependents out of plans or transferring
costs in premiums or deductibles.
We have to shop more wisely, she argues, so we can afford the
important drugs. She recalls one father with brain cancer whose
treatment cost around $40,000. The drugs bought him another year.
The treatment meant the man’s daughter was seven, instead of six
when he died, and during that year he played, talked and shared time
with her. “Was that drug worthwhile? You bet it is,” says Martinez.
“But we’ve got to quit wasting money on drugs that people really
aren’t benefiting from so that we can afford these expensive drugs.”
We can’t afford to keep spending on pricey new drugs that are no
better than their older counterparts, she says.
Doctors assume patients want the latest, greatest thing—and we’ve
got to start telling them otherwise and asking about other choices,
she says. People are often shocked at the idea of asking their
doctor why they prescribed a drug. “They’ll say, ‘But I can’t. I’m
not allowed to do that, I have to do what the doctor prescribes.’”
As well as avoiding a prescription altogether, it may often be
possible to try a lower dose of a medication to reduce risk of
side-effects. Dr. Jay Cohen, an adjunct associate professor at
University of California, San Diego in family and preventative
medicine, writes extensively about medication safety. A drug
company’s main goal is to produce a drug that outperforms the
competition, which can lead to higher doses - and more side-effects,
he says.
“They’re so focused on efficacy. They’re really focused on putting
out a drug that really, really is stronger and better than their
competitors - and they can say that in their advertising, ‘Ours helps
75% whereas theirs only helps 63%,’” says Dr. Cohen.
“But of course as you go to higher and higher dosages, just as when
you drink more alcohol or coffee, you bring more risk, and they
don’t talk about that at all. Studies have shown they really
downplay the side-effect issue.”
Drug doses aren’t necessarily created with the idea of maximizing
safety, but maximizing efficacy, which translates into maximizing
sales, he says. Dr. Cohen doesn’t recommend changing doses in acute
situations, such as infectious diseases or cancer, but says for
conditions such as depression and high cholesterol patients should
ask their doctor if they could start a medication at a lower dose.
The approach follows the medical profession’s “start low, go slow”
mantra of prescription drug use.
Drugs have historically not been tested in the elderly or women,
even though these groups are the biggest consumers of medication, he
notes. Young, healthy males can tolerate more medication, so when
you establish dose in that group, it may be too strong for others,
he says.
Dr. Cohen says many of the top-selling drugs that later showed
problems, such as the antidepressant Prozac or the painkiller Bextra,
were proven in earlier studies during the testing phase to be
effective at far lower doses than those later recommended by drug
companies - without the same side-effects.
Consumers should also be aware of their sensitivities to medication,
and inform their physicians. Dr. Cohen says if people are sensitive
to caffeine and alcohol, it may mean they’re more vulnerable to drug
side-effects. Doctors often ask about drug allergies, which are
rare, but seldom about side-effects, which are very common, he says.
Once they’re on a medication, patients also need to be aware of any
new symptoms they might experience.
“It takes a lot of people to really get harmed by these drugs before
the medical profession realizes ‘Well, maybe it’s more than we
think.’ Imagine how many patients were told ‘It’s not the drug,’”
says Dr. Cohen.
One of Public Citizen’s key rules for avoiding harm from drug
side-effects is to be alert to any changes after starting
medication.
“What we’ve told our readership for years is that if you start a new
drug and you develop a new symptom, assume it’s the new drug and not
the disease that you’re being treated for that causes the symptom,”
says Sasich.
Another good strategy is to ask your doctor if you can stop one of
your other medications when you start a new drug. “Too often there
is not a physician that has overall responsibility for all of the
patient’s drugs and physicians are loathe to discontinue a drug that
another physician has prescribed,” says Sasich. “It’s kind of like a
snowball with drugs.” The more drugs you take, he adds, the more
chance you’ll have some kind of interaction or adverse drug effect.
Consumers should keep a list of all the drugs they’re taking, and
make sure that at least one of their doctors knows about all of
them. Patients should regularly ask, “Do I still need to be taking
this? Can we lower the dose? Can we stop this one or that one?”
Sasich says patients also need good access to information that is
regulated by the government about their medication. They should
receive this information with every new and refilled prescription so
they know the risks of the drug and what steps to take if an adverse
effect appears.
Sasich and his wife, a Canadian pharmacist, have studied the
information leaflets distributed by pharmacies here and found them
lacking information. “Some of these are atrocious, they’re
absolutely worthless,” he charges.
Public Citizen keeps a list of “Do Not Use” drugs. It’s up to more
than 200. They encourage patients to look at the list before they
get a prescription filled and ask if there is an alternative “We’re
much more interested in preventing things from happening than
patients finding out that we wrote about it.”
Remember, he adds, there’s no such thing as a safe drug. All drugs
have risks, so people must take charge of their own drug safety.
