What is this medication for?
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,
osteoarthritis, and
muscle pain and to reduce fever
caused by infection. Unlike acetylsalicylic
acid (aspirin), which is also an analgesic and antipyretic, acetaminophen does
not reduce inflammation.
Acetaminophen is used by itself as well as in combination medication products
for cough, cold, and pain
relief.
