Acetaminophen is a crystalline compound classified as a non-opioid analgesic. It is also used as an antipyretic with a similar potency to aspirin. The exact mechanism of action of acetaminophen is not clear, but it does appear to inhibit the synthesis of prostaglandins. In large doses, acetaminophen can lead to acute hepatic toxicity.
In Our Own Words
Acetaminophen is an ingredient in many nonprescription drugs used to reduce fevers and treat pain. When dosed correctly, there are usually very few side effects. Acetaminophen is found in many different medications and formulations sold over the counter and at drug stores, so using the correct dose is important.
Acetaminophen may reduce pain by blocking pain signals in the body signals that chemicals called prostaglandins play a part in sending. Acetaminophen blocks some of the actions of prostaglandins, helping with pain, and is considered well tolerated, but if it is taken in higher than recommended doses, whether accidentally or in hopes of a better effect, it can lead to liver damage.
