Renal Dose Adjustments

The elimination of chlorpheniramine may be prolonged in patients with renal dysfunction. These patients should be monitored for excessive sedation and other adverse effects that may result from chlorpheniramine accumulation.

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.

Use chlorpheniramine with caution in patients with asthma.
