Common Painkiller Increases Risk of Stroke Among Diabetics

Commonly used painkiller named acetaminophen or tylenol could increase the risk of stroke among elderly patients with diabetes.

Safety of acetaminophen was studied by a team of researchers to find out the connection between the drug and major events like death, stroke and heart attack among older adults living in nursing homes in southwestern France and their findings were published in the Journal of the American Geriatrics Society.

Acetaminophen or tylenol, a widely used painkiller, is also one of the most common medications involved in overdoses and is the most common cause of drug-induced liver failure.

‘Older patients with diabetes should take pain killers exactly as suggested by the health care provider especially while using acetaminophen.’

Past research suggests that the risks caused by acetaminophen ranges from increased asthma to interactions with other medications or the risk for developing other health concerns (such as kidney toxicity, bone fractures, or blood cancers).

Another important reason to look more carefully at all medications is that our bodies may react to these treatments differently as we age. Older adults experience physical changes as they age including, for example, reduced muscle mass, more fat tissue, changes in body composition, and less fluid in the body systems.

Older people may also have multiple chronic conditions and take several different medications. These issues affect many different body functions, and that can raise your risk of having an unwanted reaction to a medication.

The researchers used information from the IQUARE study, which relied on two different questionnaires completed online by nursing home staffers. The researchers looked at deaths, heart attacks, and strokes that took place during the 18 months of the study period.

Of the 5,429 participants in the study, 3,190 were not taking acetaminophen and 2,239 were taking acetaminophen. Participants were around 86 years old and 74 percent were women.

The researchers reported that acetaminophen did not affect the number of heart attacks the participants experienced. There also was no increase in overall deaths.

The researchers found that the number of strokes was about the same in both groups--about 5 percent of the people who took acetaminophen had strokes, while about 4 percent of those who did not take acetaminophen had strokes. However, in participants who had diabetes, there was a slightly higher risk for stroke among people who took acetaminophen.

Can a Common Pain Relieving Drug Cause Liver Failure?
Acetaminophen, a common pain reliever can cause acute liver failure, finds a new study.

The researchers concluded that acetaminophen is a safe first choice in pain management for most older adults but should be considered with a bit more caution for older adults with diabetes.

As the population gets older and frailer, studies need to focus on the safety of the drugs these frail older adults commonly use to better our practice, said the researchers.

"My personal message to the people in my everyday practice is that any drug they take may have some form of harmful side effect unknown to them, even those they can buy over the counter. It is always best to check with your health care provider before you take any new medication, and make sure you’re taking the dose that’s right for you," said study author Philippe Gerard, MD.
