How much does acetaminophen reduce a fever?

The amount by which acetaminophen reduces a person's fever depends on several factors, including their age, weight, and individual response to the medication. In general, however, acetaminophen can typically reduce a fever by 1-2 degrees Fahrenheit (0.5-1.1 degrees Celsius).

The maximum recommended dosage of acetaminophen varies based on age and weight. For adults and children 12 years and older, the typical dose is 500-1000 milligrams every four to six hours, with a maximum daily dose of 4000 milligrams. For children under 12 years old, the dosage should be determined by a doctor.

It's important to follow the recommended dosing instructions and not exceed the maximum daily dose to avoid the risk of side effects, including liver damage. If a fever does not respond to acetaminophen, it's advisable to consult a healthcare provider for further evaluation.
