According to a new study, there is a possibility that acetaminophen could have an impact on emotions. Researchers said that acetaminophen might dampen emotions. As per the researchers, acetaminophen is the main ingredient in the over-the-counter pain reliever Tylenol. In the US, it has been used for over 70 years and also is the most common drug ingredient. It is found in over 600 medicines in the United States.

Every week, about 23% adults of America use a medicine that contains acetaminophen. According to the researchers, the participants who made use of acetaminophen reported less strong emotions at the time they saw both very pleasant and very disturbing photos as compared to those who took placebos.

From the previous study, it is found that acetaminophen works acetaminophen works and also on psychological pain. This research takes those findings one step further by explaining that it also decreases how much users in fact feel positive emotions.

"This means that using Tylenol or similar products might have broader consequences than previously thought. Rather than just being a pain reliever, acetaminophen can be seen as an all-purpose emotion reliever", said Geoffrey Durso, lead author of the study and a doctoral student in social psychology at The Ohio State University.

Dr. Baldwin Way, an assistant professor of psychology said that there is a possibility that the majority of people did not know how their emotions may be impacted when they take acetaminophen.

Durso carried out the study with Dr. Baldwin Way and Andrew Luttrell, another graduate student in psychology at Ohio State. The researchers are unclear whether other pain reliever has the same effect. A paper that explains findings appears online in the journal Psychological Science.
