What is acetaminophen?

Acetaminophen is a pain reliever and a fever reducer.

Acetaminophen is used to treat many conditions such as headache, muscle aches, arthritis, backache, toothaches, colds, and fevers.

Acetaminophen may also be used for other purposes not listed in this medication guide.


Do not use this medication if you are allergic to acetaminophen (Tylenol).

If you have certain conditions, you may need a dose adjustment or special tests to safely use this medication. Ask a doctor or pharmacist about using acetaminophen if you have:

  • liver disease; or
  • a history of alcoholism;

It is not known whether acetaminophen will harm an unborn baby. Before using acetaminophen, tell your doctor if you are pregnant.

This medication can pass into breast milk and may harm a nursing baby. Do not use this medication without telling your doctor if you are breast-feeding a baby.

Do not use any other over-the-counter cough, cold, allergy, or pain medication without first asking your doctor or pharmacist. Acetaminophen (sometimes abbreviated as "APAP”) is contained in many combination medicines. If you use certain products together you may accidentally use too much acetaminophen. Read the label of any other medicine you are using to see if it contains acetaminophen or APAP.

Avoid drinking alcohol while taking this medication. Alcohol may increase your risk of liver damage while taking acetaminophen.

Seek emergency medical attention if you think you have used too much of this medicine.

The first signs of an acetaminophen overdose include loss of appetite, nausea, vomiting, stomach pain, sweating, and confusion or weakness. Later symptoms may include pain in your upper stomach, dark urine, and yellowing of your skin or the whites of your eyes.

Since acetaminophen is often used only when needed, you may not be on a dosing schedule. If you are using the medication regularly, use the missed dose as soon as you remember. If it is almost time for your next regularly scheduled dose, skip the missed dose and use your next dose as directed. Do not use extra medicine to make up for a missed dose.
