Acetaminophen is a pain reliever and a fever reducer medication. It is used to treat mild to severe pain in conjunction with opiates or to reduce fever. Acetaminophen reduces pain and fever quickly caused by a headache, osteoarthritis, muscle ache, backache, toothache, cold and fever. It may also be used for the purposes as determined by the physician. This drug belongs to the analgesic (pain reliever) and antipyretics (forever reducer) group of drugs. Unlike other ASA or acetylsalicylic acid, this drug inhibits the synthesis of prostaglandins that transmit pain signals to the brain. It only blocks the signaling of pain but it does not have an anti-inflammatory action. Acetaminophen is available over-the-counter and as a prescription drug in various dosages.
