How does this medication work? What will it do for me?
Acetaminophen belongs to a group of medicines called analgesics (pain relievers) and antipyretics (fever reducers). It works quickly to relieve pain caused by conditions such as headache and osteoarthritis, and to reduce fever caused by infection. Unlike acetylsalicylic acid (ASA), which is also an analgesic and antipyretic, acetaminophen does not reduce inflammation.
