About the Campaign


More than 80 million Americans take OTC pain medicines every week for different reasons — pain, cold and cough, flu, allergies, sleep and morei,ii. The Gut Check: Know Your Medicine campaign has the resources to help you be comfortable, enjoy life and try to do what’s needed to better control your pain. The American Gastroenterological Association developed the campaign in an effort to reduce the amount of preventable health issues that thousands of people face every year.

It is estimated that in the U.S. each year the risk of death related to medications is 35 deaths for acetaminophen, 64 deaths for ibuprofen and 118 deaths for naproxen sodium per million in the populationiii. Gastroenterologists often see patients with these complications and want you to know how to safely use your medicine. In most cases, the simple act of reading and following your medicine labels can help to prevent harmful medication interactions or overdose.

Overdose of common active ingredients, such as acetaminophen and NSAIDs, can lead to harmful side effects, like gastrointestinal bleeding or liver damage. By reading and understanding your medicine labels, you can determine which medicines share the same ingredients that could be harmful when doubled.
