Are You Taking Too Much Ibuprofen?
Over-the-counter drugs known as NSAIDs can cause ulcers, kidney failure and stroke
(This article appeared previously on MedShadow.)
Headache. Aching or injured back. Sore muscles or joints after overdoing it on the tennis or basketball court or golf course. Or even a long day in the garden.
These aches and pains are among the reasons that every day, nearly one in five Americans (17 percent) turn to a group of over-the-counter and prescription pain relievers collectively known as NSAIDs – nonsteroidal anti-inflammatory drugs. The best-known ones are ibuprofen (Advil, Motrin), naproxen (Aleve) and good old aspirin.
They work — and work well — by blocking the production of substances in the body called prostaglandins that trigger pain and inflammation.
Even as misuse and abuse of stronger opioid pain relievers gets all the media attention, there’s long been concern that NSAIDs, too, are overused. And that overuse may be on a much larger scale since it involves tens of millions of Americans who take the medicines regularly for mild pain and muscle soreness, pain that almost always resolves itself in a couple days.
Many older people also take these medicines on a regular basis (often every day) for the joint pain and stiffness associated with osteoarthritis and normal aging. About one-third of adults age 65 and older have osteoarthritis.
Serious Side Effects Associated with NSAIDs
The concern on both counts revolves around the quite serious side effects the medicines can cause, and the risks they pose — especially if overused at higher doses for long periods. Two recent reports from Consumer Reports discuss the issue and offer detailed recommendations.
“There’s little doubt that NSAIDs are overused for the everyday aches and pains that come with advancing years,” says Marvin M. Lipman, M.D., chief medical adviser at Consumer Reports. “Long-term use of any painkiller requires close medical supervision.”
Here’s the most salient advice distilled from both articles, which draw on the latest research:
- All of the NSAIDs — there are about 20, with some available only by prescription — can cause serious side effects. These include stomach ulcers, gastrointestinal (GI) bleeding, kidney failure, heart attacks and strokes. Aspirin is the exception. It can cause GI bleeding and stomach ulcers but not heart attacks and strokes. Indeed, at low doses, aspirin can help prevent heart attacks and strokes, which are caused by blood clots that aspirin can counter.
- The risk of GI and stomach ulceration and bleeding is more serious than most people think. An estimated 7,000 to 10,000 Americans die each year from this NSAID risk. That risk increases with age and with length of use. People 75 and over have about a 1 percent chance of gastrointestinal bleeding if they take an NSAID for over a week or so. (See table below.)
- People of any age who have previously had stomach bleeding or ulcers should consider taking acetaminophen (Tylenol) instead of an NSAID for minor aches and pains.
- If you are taking corticosteroids, or blood thinners — for example, clopidogrel (Plavix) or warfarin (Coumadin) — tell your doctor before taking an NSAID. These medicines also increase the risk of bleeding and thus add to the risk of bleeding you’ll get from an NSAID.
- The bleeding risk is dose and time dependent. That is, taking an NSAID every day at high doses for long periods (more than a few weeks) increases the chances of experiencing a bleeding episode — for people of any age. In contrast, taking NSAIDs every so often (as much as once or twice a week) at low doses does not appear to be associated with any significant stomach or GI bleeding risk. That puts most of us in the clear. But everyone should abide by the general advice to take the lowest dose of an NSAID that brings relief and take it for as short a time as possible.
Risk of Heart Problems and Stroke
If you have heart or kidney disease or have high blood pressure, or are considered at risk of having a heart attack or stroke for any reason, talk with your doctor about limiting the use of NSAIDs and taking an alternative medicine instead. All NSAIDs (except aspirin) carry a warning on their labeling that if used in certain ways they have the potential to increase the risk of heart attack and stroke.
- Acetaminophen (Tylenol) is the most commonly used alternative to NSAIDs. It isn’t as effective at relieving some pains — such as muscle and joint pain — as an NSAID, but it doesn’t carry a risk for stomach bleeding or heart attack or stroke.
- The precise dose or length of use at which the heart risks of NSAIDs outweigh the benefits can’t be easily pinned down. The risk differs from person to person. As a rough rule of thumb, though, studies indicate that taking 800 mg (four pills) or more of an NSAID every day for a few weeks or more increases a 55-year-old man’s risk of heart attack by 50 percent to 100 percent. Since the risk is small to begin with, the increased risk is also small. (By way of illustration, if a risk starts out at 1 in 100 and doubles, it’s 2 in 100, still small but not negligible.)
- Research indicates that all NSAIDs, except naproxen and aspirin, carry about the same heart attack and stroke risk.
- Naproxen may be a better choice for people who have higher risk of heart attacks or strokes, since the available evidence indicates it doesn’t increase the risk of these conditions as much as other NSAIDs.
- NSAIDs can aggravate high blood pressure, which is one way they could raise the risk of heart attack. They also cause fluid retention, which can lead to slight weight gain or swollen legs even in healthy individuals.
- For people who have a “weak heart” (due to congestive heart failure, for example) fluid retention due to NSAIDs could make symptoms worse and increase the risk of hospitalization.
- NSAIDs have been associated with kidney failure, so people with kidney disease due to diabetes or other causes should not take NSAIDs unless your doctor has said it is appropriate for your situation.
- If your doctor prescribes an NSAID, tell him or her about any other medicines or dietary supplements you are taking, including daily aspirin to reduce your risk of heart attack or stroke. NSAIDs can interact with other medicines, including other NSAIDs, such as aspirin, and can increase the risk of having a serious side effect.
