Prescription Drugs Side Effects: Could Prescription Drugs Be Making You Ill?

There's no other way to put it: Far too many doctors are letting elderly people down.

A new study from Duke University in the US reveals disturbing evidence that more than 20 percent of all elderly people who are prescribed drugs are receiving medications that are known to be harmful to older patients.

This lapse in 'care-giving' is nothing less than shameful. But it serves as a stark warning: No one should meekly accept what a doctor prescribes. Ask questions. Research. Take control of your health care.

Slipping through the cracks
In the early 90s, Dr Mark Beers, and several other specialists in geriatric drug therapy, developed a list of medications that were inappropriate for nursing home residents. The list - now known as the Beers List - was amended in 1997, and updated in 2003, and has become a well known tool for guiding doctors away from prescribing medications that may be harmful when taken by older patients.

In an interview with HealthDayNews, Dr Kevin Schulman, a professor of internal medicine at Duke University and one of the authors of the study, said that even though someone over the age of 65 may be in good health, their kidneys don't function as well as they did when they were younger. This is one of the primary reasons that some medications can be harmful. Antidepressants and muscle relaxants can put particular stress on the kidneys.

The Duke team examined the outpatient prescription claims for more than 765,000 people aged 65 or older who had more than one prescription filled during 1999. Using the Beers List, the researchers produced this data:

• More than 20 percent of patients over the age of 65 may be taking inappropriate prescription drugs
• More than 15 percent of these patients received prescriptions for two or more of the drugs on the Beers List
• Four percent of the patients were prescribed three or more drugs on the list
• Psychotropic drugs (such as antidepressants) on the Beers List were prescribed the most, totalling more than 40 percent of the prescriptions
• Muscle relaxants on the Beers List were the second most commonly prescribed

Obviously, there are quite a few doctors out there who are asleep at the switch. And as a result, their patients may be suffering.

Adding up the danger
Kidney stress caused by drugs on the Beers List is by no means the only health problem older people face when taking prescription drugs.

These drugs can also interfere with the absorption of nutrients. For instance, acid blockers (such as Prilosec and Nexium) have been shown to significantly decrease absorption of vitamin B-12; one of the primary vitamins needed to prevent anaemia.

Other medications that are known to play a role in nutrient depletion are among the most frequently prescribed drugs on the market. Antibiotics, anti-depressants, anti-inflammatories, blood pressure medications, cholesterol-lowering drugs, oestrogen, and tranquillisers can all strip valuable vitamins and minerals from the body. When two or more of these drugs are combined - especially in an older patient - the risk of developing anaemia rises.

And that's when things can get really complicated, because anaemia dramatically increases mortality risk for patients with chronic health problems such as heart disease and cancer.

How much can you take?
The harm that a single drug may do - by stressing the kidneys and depleting nutrients - is small compared to the harm that can occur when several drugs are taken at the same time.

In a previous e-alert I told you about a US study which revealed this shocking statistic: the average elderly person receives 25 prescriptions annually - a 100 percent jump from just five years ago!

If the statistics in the UK are anything like this then we need to take urgent action.

As the over-medication of older people grows at an alarming rate, we see two serious problems becoming even greater health threats: 1) the wider variety of drug intake creates conflicting side effects (and as we've seen before, many doctors treat drug side effects with additional drugs), and 2) these potent drug mixes rob patients of the very nutrients they need most when fighting an illness.

New coin
A few days ago I came across a word that was new to me: Polypharmacy. This is the practice of prescribing too many medications.

Along with polypharmacy I would coin this word: Negligentpharmacy; the practice of prescribing drugs that are known to be harmful to certain patients.

Unfortunately, many older people are victims of both polypharmacy and negligentpharmacy because too many doctors are not well trained or conscientious enough to know the harm that some drugs may cause. That's why young and old patients alike have to be diligent whenever their doctor writes a prescription.
