Know your pills, assess dangers, consume wisely

2 Why? Because some people naïvely believe it's possible to get a health benefit without risk. Today, millions are popping a variety of over-the-counter pain relievers while ignoring important red flags warning they may result in death.

Heart and stroke risk

The American Heart Association reports that, with the exception of acetylsalicylate acid (Aspirin) and possibly naproxen (Aleve), non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen (Motrin and Advil) increase the risk of heart attack and stroke. This is particularly true for those who have already had a heart attack or are at high risk of cardiovascular disease.

Now, a report in the journal Circulation has more disturbing news. Dr. Anne-Marie Olsen, a researcher at the Copenhagen Hospital in Denmark, reports that patients who have had a previous coronary attack and now take painkillers have a 30 per cent increased risk of dying after one year. In another Danish study, the risk increased even in healthy people.

Gastrointestinal (GI) risk

It's estimated about 24,000 North Americans taking NSAIDs die from GI bleeding every year. NSAIDs block the enzyme COX-1 that normally protects the stomach's lining. The risk is greater for those using NSAIDs for a prolonged time, those over age 60 and those who take blood-thinning medication or steroids. Some studies reveal as many as five to 10 per cent of NSAIDs users experience an episode of bleeding or develop a stomach ulcer in any given year. Stomach medication can help decrease this risk.

Blood pressure

Aspirin tends to lower blood pressure if taken at night. NSAIDs have been linked to increases in blood pressure, particularly for those being treated for hypertension.

Kidney risk

NSAIDS, and to a lesser extent acetaminophen (Tylenol), can damage kidneys if used over a long period. About five per cent of patients now on kidney dialysis would not be attached to these life-saving machines if they had not abused their kidneys by taking too many minor painkillers. This is a huge price to pay for popping pills that in many cases are not needed.

Liver risk

Acetaminophen (Tylenol) is a good pain-reliever and does not pose the same danger to the cardiovascular system or gastrointestinal tract. But like any medication, it must be taken correctly. Unfortunately, the common error is to overdose. It's so easy to fall into this trap. Since several other pain-relievers contain acetaminophen, people may consume more than they realize. The best precaution is to always read the labels on pain medication to make sure you're not doubling or tripling the dose.

Too much Tylenol is toxic to the liver, particularly if consumed in large amounts with alcohol. Today, acetaminophen poisoning (half of these cases are accidental) is the leading cause of liver failure in the United States.

A fact many consumers don't know

Today, many people are taking an 81-milligram Aspirin tablet to decrease the risk of coronary attack. Aspirin works by making platelets slippery so they are less likely to form a fatal blood clot. It accomplishes this by attaching itself to an enzyme called cyclooxygenase that controls the level of thromboxane A2. It, in turn, controls platelet stickiness. But naproxen and ibuprofen also seek out this enzyme and if they arrive first, there's no room for Aspirin. So it's prudent to take Aspirin 30 minutes before these medications or eight hours after.

Don't stop NSAIDs cold turkey

A report from The Harvard Medical School claims a sudden stoppage of this medication makes it more likely a blood clot will form.

Don't abuse painkillers

Patients with arthritis and other chronic conditions may need these painkillers. Here, the benefit far outweighs the risk. But too many people take them for trivial aches and pains, causing needless injury to liver and kidneys.
