Acetaminophen Dosage

Acetaminophen (e.g. Tylenol) is a medication that is used to treat fever, and mild to moderate pain. As in the case of any medication, the right dosage must be used to ensure the optimum effect with a minimum of side effects. The table below will help you to evaluate the dosage to be given to a child, based on his/her weight. Usually, acetaminophen is given in doses of 10 to 15 mg per kilo of weight, every 4 hours.

You will note that the dosages are given in millilitres (mL) rather than in teaspoons. This is because teaspoons are not accurate enought for measuring medication. Ask your pharmacist to give you a dosing syringe or another measurement device that will enable you to obtain accurate dosages at all times.
