Summary
Many emergency department visitors lack knowledge about safe acetaminophen use and its liver toxicity risks. This highlights a critical gap in public understanding of this common pain reliever.
Area of Science:
- Toxicology
- Public Health
- Emergency Medicine
Background:
- Acetaminophen (APAP) overdose is a leading cause of acute liver failure.
- Understanding public knowledge of APAP is crucial for preventing toxicity.
Purpose of the Study:
- To assess emergency department visitors' knowledge of acetaminophen therapeutic dosage and toxicity.
- To identify potential gaps in public awareness regarding safe APAP use.
Main Methods:
- A questionnaire survey was administered to adult visitors in an urban/suburban emergency department waiting room.
- 103 out of 138 approached subjects (75%) completed the survey.
Main Results:
- 18% incorrectly believed the maximum daily dose of acetaminophen is 5 grams or more.
- Only 13% correctly identified Percocet and 6% Vicodin as containing acetaminophen; many mistakenly believed Motrin did.
- 52% were unaware that acetaminophen toxicity can cause liver damage.
Conclusions:
- A significant portion of surveyed individuals demonstrated limited knowledge regarding appropriate acetaminophen dosing and its potential for liver toxicity.
- Educational interventions are needed to improve public understanding of safe acetaminophen use and associated risks.
