Abstract
ObjectivesTo evaluate college-age women’s knowledge of appropriate doses and potential toxicities of acetaminophen, competency in interpreting Drug Facts label dosing information, and ability to recognize products containing acetaminophen. MethodsIn this cross-sectional prospective study, a 20-item written survey was provided to female college students at a University of Michigan fundraising event in March 2015. ResultsA total of 203 female college students, 18-24 years of age, participated in the study. Pain was experienced on a daily or weekly basis by 22% of the subjects over the previous 6 months, and 83% reported taking acetaminophen. The maximum 3-gram daily dose of extra-strength acetaminophen was correctly identified by 64 participants; an additional 51 subjects indicated the generally accepted 4 grams daily as the maximum dose. When provided with the Tylenol Drug Facts label, 68.5% correctly identified the maximum amount of regular-strength acetaminophen recommended for a healthy adult. Hepatotoxicity was associated with high acetaminophen doses by 63.6% of participants, significantly more than those who selected distracter responses (P < 0.001). Knowledge of liver damage as a potential toxicity was correlated with age 20 years and older (P < 0.001) but was independent from race and ethnicity and level of alcohol consumption. Although more than one-half of the subjects (58.6%) recognized that Tylenol contained acetaminophen, fewer than one-fourth correctly identified other acetaminophen-containing products. ConclusionDespite ongoing educational campaigns, a large proportion of the college-age women who participated in our study did not know and could not interpret the maximum recommended daily dose from Drug Facts labeling, did not know that liver damage was a potential toxicity of acetaminophen, and could not recognize acetaminophen-containing products. These data suggest a continued role for pharmacists in educational efforts targeted to college-age women.
