It is recommended that patients take no more than 4,000 milligrams of acetaminophen per day.
A study was conducted on more than 300 patients who were admitted to a hospital for acetaminophen overdose. Of all the patients, nearly 7 percent suffered severe liver damage. Fortunately, all of the patients recovered and there were no deaths.
Symptoms of overdose and liver damage include:
- Dark-colored urine
- Clay-colored stools

It is recommended that patients avoid Tylenol side effects by refraining from alcohol consumption during use.
Patients who consume more than 3 alcoholic beverages per day should speak with their doctor before taking Tylenol. Additionally, those who have had cirrhosis of the liver should also speak with their doctor before beginning acetaminophen treatment.
