Which condition may result from excessive Tylenol consumption?

• A. Cirrhosis
• B. Hepatitis
• C. Pancreatitis
• D. Cholecystitis

Answer: (A)

Excessive Tylenol use injures the liver, which is the organ responsible for metabolizing this medication. When taken in large amounts or over a long period, the toxin formed during metabolism can overwhelm the liver’s protective systems, causing hepatocellular damage. If this ongoing injury persists, the liver responds with fibrosis and scarring, ultimately progressing toward cirrhosis. This makes cirrhosis the most likely outcome among the given options when Tylenol is used excessively over time.

Hepatitis refers to liver inflammation that has many causes (infections, alcohol, autoimmune disease, drugs other than Tylenol, etc.), but cirrhosis specifically describes the end-stage scarring process that can result from chronic liver injury. Pancreatitis and cholecystitis involve the pancreas and gallbladder, respectively, and are not typical direct consequences of acetaminophen overuse.
