Acetaminophen Dosing

ACETAMINOPHEN (Tylenol)

Acetaminophen may be safely used by children of all ages. Children with a known or possible allergy to acetaminophen, with liver disease, or who drink alcohol should not take acetaminophen without talking first with a physician.

Even small overdoses of acetamiophen may be dangerous if given repeatedly several times per day. So, please check the dose carefully. Be careful if giving acetaminophen along with combination medications (like cough/cold medications or pain relievers like Percocet) to be sure that those combination medications do not also contain acetaminophen.

Acetaminophen may be given as often as every 4 hours. However, it is best if acetaminophen is not given more than 4 or 5 times per day.
