Are you taking too much NyQuil? The surprising futility of drug labeling

(Press-News.org) Any box or bottle of over-the-counter (OTC) medicine lists its active ingredients prominently on the label. But are consumers using that information to make wise choices about taking two or more OTC drugs at the same time? Probably not, suggests a new study in the Journal of Public Policy & Marketing.
"A consumer who takes a cold medicine containing, for instance, acetaminophen, may see nothing wrong with taking an additional medicine that also contains acetaminophen," write authors Jesse R. Catlin (California State University, Sacramento), Connie Pechmann (University of California, Irvine), and Eric P. Brass (UCLA). "But in that case, he or she will likely ingest at least 1300 mg of acetaminophen, and if those doses are repeated every 4-6 hours, the consumer will take in at least 5200 mg of acetaminophen per day, well over the limit."
Study participants included people with and without medical expertise. They were asked to read the labels on the packages of two different OTC drugs and report whether the two contained the same active ingredients. They were also asked to judge the risks of taking the two drugs at the same time. Both groups of participants--those with and without medical expertise--correctly determined whether the two drugs contained the same active ingredients. But only participants with medical expertise used that information to weigh the risks of taking two medications together.
In other words, the typical consumer, who is unlikely to have any medical expertise, may very well believe that there is no danger in taking any two OTC medications at the same time--even medications with the same active ingredients. This, the authors suggest, reflects the fact that the average person believes OTC drugs to be risk-free. Because of that "naïve" belief, most consumers are at risk of overdosing on nonprescription drugs. The authors suggest that standard labels be supplemented with public service announcements and explicit warnings on the labels themselves.
"Programs to educate the public on the risks of double-dosing must clearly emphasize that even over-the-counter medications can be dangerous when combined or misused. More broadly, this study suggests that it is vitally important for practitioners and policymakers to address safety issues by first working to understand what is at the root of the consumer's misunderstanding," conclude the authors.

You go to the grocery store to buy a pound of ground beef and a can of tomato sauce. You walk out with the ground beef, the sauce, and a bag of chocolate-covered almonds, a silicon spatula, and the latest celebrity magazine. What happened? According to a new study in the Journal of Marketing, what and when you purchased determined the array of items you eventually bought.
"Shoppers enter the grocery store planning to buy certain things, but are tempted to buy unplanned items," write authors Timothy J. Gilbride (University of Notre Dame), Jeffrey Inman (University of Pittsburgh), ...

Consumers often complain that online companies violate their privacy--but the problem may be with the consumers themselves. According to a new study in the Journal of Public Policy & Marketing, there can be a big discrepancy between what consumers believe that online privacy policies promise and what those policies do in fact promise. Many consumers assume policy protections that were never there.
"The difference between the level of privacy consumers think they have after reading a privacy notice and the level of privacy they actually have can be striking," writes the ...

A new study by a University of Toronto Mississauga researcher has taken the first-ever look at the academic outcomes of children with epilepsy who have had brain surgery, and found that they have a higher chance of struggling in class following their surgery.
Psychology professor Mary Lou Smith was co-leader of a team of researchers who studied the arithmetic, spelling, reading and reading comprehension abilities of children after having resective epilepsy surgery, a procedure that involves removing a part of the brain in order to halt seizures. The patients completed ...

Not too long ago, Microsoft mailed loyal Xbox customers an e-card encoded with twenty-five cents' worth of Microsoft points. The software behemoth might have thought it was showing appreciation. But recipients of the company's "generosity" might have felt "Is that all I'm worth?" According to a new study in the Journal of Marketing, companies that bestow monetary gifts in too small amounts can leave customers feeling, well, small.
"Financial acknowledgments, if they are too insignificant, can definitely backfire," write authors Peggy J. Liu (Duke University), Cait Lamberton ...

They say you never get a second chance to make a first impression. When it comes to selling, that might be a good thing, suggests a new study in the Journal of Marketing.
"Salespeople can make accurate intuitive judgments of a customer's needs, and those judgments can significantly increase sales," write authors Zachary R. Hall (Texas Christian University), Michael Ahearne (University of Houston), and Harish Sujan (Tulane University). "In fact, when a salesperson deliberately rethinks first impressions of a customer, he or she might lose a potential sale."

Some 30,000 years ago, prehistoric man wielded animal bones as needles to suture otherwise lethal wounds. This tactic has been used, and improved upon, over time and remains the basis of surgical procedures conducted today. Even with radical new surgical techniques, which rely on metallic and polymeric staples or chemical adhesives to seal incisions, infection and permanent scarring remain major concerns. The success of any wound closure is entirely dependent on the physician's skill set alone.

COLUMBIA, Mo. - Research has shown that media, such as television and video games, can affect viewers' thoughts and actions. Now, new research by Cynthia Frisby, an associate professor of strategic communication in the University of Missouri School of Journalism, has revealed racial stereotyping in the way media portray athletes. Frisby found that media stories on African-American athletes focus primarily on criminal actions while stories about white athletes are overwhelmingly positive.
For her study, Frisby examined 155 news articles about male athletes from online ...

Why do people participate in programs that benefit the environment, even when there seems to be no direct personal benefit in taking part? More specifically, why would consumers pay good money for wind energy when it is not at all clear that they are benefiting from that energy? The answer may lie in a psychological sense of community with other wind-energy customers, according to a new study in the Journal of Public Policy & Marketing.
The authors interviewed participants in a wind power program in the western United States. The goal was to understand in depth what ...

New Orleans, Louisiana - June 2, 2015 - Data confirms that there is transmission of fecal coliforms in communal bathrooms at Quinnipiac University and that toothbrushes can serve as a vector for transmission of potentially pathogenic organisms. This research is presented at the annual meeting of the American Society for Microbiology.
"The main concern is not with the presence of your own fecal matter on your toothbrush, but rather when a toothbrush is contaminated with fecal matter from someone else, which contains bacteria, viruses or parasites that are not part of your ...

The impact of scary TV on children's wellbeing has been overstated, according to University of Sussex psychologists.
While research has shown that a small minority of children can have extreme reactions to a scary programme or film, the researchers found that, overall, children show very little sign of increased anxiety, fear, sadness or sleep problems.
University of Sussex research student, Laura Pearce, and Andy Field, Professor of Child Psychopathology at the University, reviewed all research into the topic carried out over the past 25 years.
Their findings, ...
