Acetaminophen is the most common drug ingredient in America. Fioricet capsules contain a combination of acetaminophen, butalbital, and caffeine. Acetaminophen is a pain reliever and fever reducer. Butalbital is in a group of drugs called barbiturates. It relaxes muscle contractions involved in a tension headache. Caffeine is a central nervous system stimulant. It relaxes muscle contractions in blood vessels to improve blood flow.

More than 600 medicines contain acetaminophen. These include both prescription medicines and medicines available without a prescription, also called “over-the-counter,” or “OTC” medicines. To prevent acetaminophen overdose, you need to be able to read labels and recognize when their medicines contain acetaminophen.

The active ingredients in OTC medicines are clearly listed on the label, and the word “acetaminophen,” is listed on the front of the package or bottle and in the Active Ingredient section of the Drug Facts label. On prescription labels, acetaminophen is sometimes listed as “APAP,” “acetam,” or other shorted versions of the word.

To know what is in your medicines, read the list of active ingredients on the label each and every time you take a medicine.
