You may be taking too many drugs. But how can you tell?
By Dr. Mary James, ND
I don’t know many women who reach mid-life without taking at least one prescription
drug. Maybe you’re taking medications for arthritis, heartburn, headaches or allergies.
Everybody’s got something, right? And quite a lot of us have more than one “something”
But taking prescription drugs has its own risks.
What drugs do — and don’t do
You go to your doctor with a complaint — typically a bothersome symptom. She will
diagnose the reason, sometimes after a lab test, and typically treat you with a
prescription drug. This prescription medication — whatever it might be for — works
by sending a chemical signal to change the function of certain cells or systems
or organs. The drug generally will suppress the symptom. But it doesn’t affect the
Here’s how that works. If you’re having
acid reflux, for example, you might take a medication called a proton pump
inhibitor (PPI). Because it suppresses an enzyme that naturally makes your stomach
produce acid, the drug leads to less stomach acid and less reflux. Or you might
take a medication called an H2 blocker that prevents histamine from attaching to
receptors in the stomach. The result is the same — your stomach produces less acid.
But neither drug actually addresses the reasons for acid reflux or heartburn in
the first place.
If you don’t explore the “why” part of what’s happening in your body, you may find
yourself using the medication over the long term. And possibly in increasing amounts
because the medication may become less effective as your body adapts to this new
input. Not surprisingly, longer-term use increases the odds of developing side effects,
many of which are as bad as the original problem. For example, long-term use of
PPIs causes vitamin B12 deficiency in many women. Without realizing what’s happening,
you find yourself falling into what’s called a “prescribing cascade.”
How does one prescription become many prescriptions?
A prescribing cascade occurs when a medication you’re prescribed for one problem
produces side effects that lead to the prescription of another medication.
Let’s say you’ve been taking that PPI for acid reflux for a year or two. One of
the unfortunate long-term side effects of PPIs is that it can set the stage for
bacterial overgrowth in the small intestine. So your acid reflux may be held back
by the PPI. But then you develop bloating and impaired nutrient absorption related
to bacterial overgrowth.
You’re then given an antibiotic to reduce the intestinal bacterial load. But this
causes diarrhea. If diarrhea is particularly severe, the prescription anti-diarrheal
medication, loperamide, may be offered.
You’ve now gone from one medication to treat reflux to three different medications.
One for the original problem. Two for the side effects related to treatment.
And with all this, you still haven’t actually resolved the cause of your reflux!
What are the long-term effects on your body?
Your body has a different point of view than most doctors. From your body’s perspective,
most medications are a problem. Unlike nutrients that help build tissue or maintain
function, your body doesn’t welcome drugs. They’re disruptive foreign chemicals
— often toxic — so they need to be removed from circulation as soon as possible.
Various enzymes in your liver work to break them down and send them off to be excreted
in the urine or feces.
But a lot of medications are metabolized by the same liver enzymes, which means
they compete for the enzymes’ “attention.” This distracts the liver from its other
vital functions and increases its toxic load.
Worse, some of those medications actually inhibit the activity of key enzymes
in the liver. This can slow down the whole process of detoxification even more.
What is considered a standard dosage for medications that use that slowed-down enzyme
can now act like toxic doses in the body. Unfortunately, as we get older, our liver
and kidneys already tend to become less efficient. Blood flow in the liver can decline
by as much as 40% and in the kidneys by up to 50% by the time we reach the age of
80. So these toxic loads are really burdensome — increasing the odds of side effects.
Ridding ourselves of metabolites from these medications becomes significantly harder.
It also means that when other toxic substances enter our system — which happens
on a daily basis — our liver and kidneys have a difficult time metabolizing them.
This can potentially make us pretty sick.
Keep two things in mind. First, drugs are typically tested in isolation, even though
they’re used in combination with other drugs — so we don’t really know how they
interact in the body. That’s especially true since about half of all drugs are prescribed
“off label” — that is, they’re used for a purpose other than what was originally
approved by the FDA. Second, interactions of all substances in the body are unbelievably
complex, probably beyond the computing power we have today, even if we had a complete
model of how the body works. Which we don’t.
What are your symptoms telling you?
Integrative and alternative doctors advocate a different view of symptoms. While
a conventional doctor usually sees the symptom as a problem, we see the symptom
as your body telling you, “Something’s not right.” We want to answer the “and why”
question first: Why is the symptom happening in the first place? Once the underlying
cause of the symptom is identified, we can take care of it, perhaps with less —
or no — prescription medication.
Let’s go back to the example of acid reflux: depending on the individual, the underlying
problem could be one of many, including:
- hidden food allergies (which could be why so many women find relief with H2-blockers,
which are antihistamines)
imbalanced gut flora
- a thinner protective mucus barrier in the stomach
- not enough stomach acid (yes, you read that right!)
- Helicobacter pylori infection
- eating large meals late in the day
That leads us to another reason to avoid the “prescription cascade”: By treating
your symptoms without uncovering their root cause, you could inadvertently mask
a bigger issue that, untreated, grows worse.
For example, let’s say you have celiac disease and you simply use medications to
relieve symptoms of heartburn, diarrhea and bloating. Without uncovering the fact
that eating gluten is the foundation of your illness, the long-term consequences
can be devastating: chronic fatigue, osteoporosis, anemia and malnutrition, to name
Unfortunately, this is a common pattern in the treatment of chronic disorders. Conventional
medicines mostly treat the symptoms, not the underlying conditions that give rise
to the symptoms. As a result, the patient ends up with multiple prescription medications,
but not optimal health. Symptoms might be temporarily ameliorated, but the underlying
disease continues to progress and you’re prescribed more and more drugs over time.
How to avoid being a victim of the “prescription cascade”
Even if you start by addressing your symptoms with a “quick fix” medication, you
are more likely to achieve lasting relief and better health by going after the underlying
cause of your problem, rather than just treating the symptoms. You’ll also experience
less medication, lower costs and fewer long-term complications. Start by getting
some help in identifying what your symptoms are saying about what your body needs.
If your doctor is too conventional to consider that approach, I suggest finding
a practitioner who’s more open-minded and up to date.
Over-medication is recognized by leaders of both conventional and alternative medicine
as a genuine problem that leads to worse health outcomes for patients. While we
all know that, it’s still hard to change the pattern of symptom-test-prescription-drug.
And certainly there are complex cases where a host of medications is what’s best
for the patient. But for most of us — it isn’t. And the reality is, your own clear
thinking is the best defense.
