What is the most important information I should know about acetaminophen and butalbital?

Do not take more of this medication than is recommended. An overdose of acetaminophen can damage your liver or cause death.

Tell your doctor if you have ever had alcoholic liver disease (cirrhosis) or if you drink more than 3 alcoholic beverages per day. You may not be able to take medicine that contains acetaminophen.

Before you take acetaminophen and butalbital, tell your doctor if you are allergic to any drugs, or if you have liver or kidney disease, a stomach or intestinal disorder, or a history of drug or alcohol addiction.

Butalbital may be habit-forming and should be used only by the person it was prescribed for. Never share this medication with another person, especially someone with a history of drug abuse or addiction. Keep the medication in a place where others cannot get to it.

Tell your doctor if the medicine seems to stop working as well in relieving your pain.

This medication may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert.

Ask a doctor or pharmacist before using any other cold, allergy, pain, or sleep medication. Acetaminophen (sometimes abbreviated as APAP) is contained in many combination medicines. Taking certain products together can cause you to get too much acetaminophen which can lead to a fatal overdose. Check the label to see if a medicine contains acetaminophen or APAP.

Avoid drinking alcohol. It may increase your risk of liver damage while taking acetaminophen.
