Renal Dose Adjustments

Data not available

Liver Dose Adjustments

Use with caution in patients with liver disease. Chronic use of acetaminophen is not recommended in patients with liver disease.

Precautions

Patients who consume three or more alcohol containing drinks per day should be informed to consult with their physician for advice on when and how to take acetaminophen. Chronic, heavy alcohol users may be at increased risk of liver damage when taking more than recommended dosages.

Patients and adults taking care of children should be advised to consult with their doctor before continuing to use acetaminophen if symptoms of illness worsen. Although rare, there is the possibility of acetaminophen intoxication on chronic use of the drug, and the symptoms seen during the first phase of intoxication (nausea, vomiting, anorexia, malaise, and diaphoresis) may trigger the use of more doses.
