What symptom can signal liver damage when using Tylenol?

Dark urine can indicate liver damage when using Tylenol (acetaminophen). The liver plays a crucial role in metabolizing various substances, including medications like Tylenol. When the liver is damaged or stressed, it may not be able to process waste products efficiently, leading to the accumulation of bilirubin in the bloodstream. This excess bilirubin can cause the urine to turn dark in color, often described as tea-colored or brown.

Recognizing this symptom is vital because it can serve as an early warning sign of potential liver injury, allowing for timely medical intervention. Monitoring for other symptoms, such as jaundice (yellowing of the skin and eyes), abdominal pain, or fatigue, can further indicate liver dysfunction. Being aware of these symptoms helps ensure the safe use of Tylenol and other medications that impact liver health.
