Acetaminophen, the active ingredient in Tylenol, is generally considered safe when taken as directed. However, regular use of Tylenol can lead to stomach damage due to the potential for overuse and accumulation of the medication in the body.

One of the primary concerns with regular Tylenol use is the risk of acetaminophen-induced liver damage. According to the American Liver Foundation, acetaminophen is the leading cause of liver failure in the United States [1]. Prolonged use of Tylenol can cause liver damage, particularly in individuals who consume three or more acetaminophen-containing products per day [2].

Another potential risk associated with regular Tylenol use is stomach ulcers and bleeding. A study published in the Journal of Clinical Gastroenterology found that long-term use of acetaminophen was associated with an increased risk of gastrointestinal bleeding and ulcers [3]. This is because acetaminophen can irritate the stomach lining, leading to inflammation and potentially causing ulcers.

Furthermore, regular use of Tylenol can also lead to stomach damage due to the potential for overuse. Taking more than the recommended dose of Tylenol can cause stomach upset, nausea, and vomiting. Additionally, taking Tylenol with food or milk may not reduce the risk of stomach damage, as the medication can still irritate the stomach lining [4].

It is essential to note that the risk of stomach damage from regular Tylenol use can be minimized by following the recommended dosage and taking the medication with food. However, it is crucial to consult with a healthcare provider before taking Tylenol, especially for extended periods or in high doses.
