Acetaminophen is an effective alternative to aspirin when only the relief of pain and reducing a fever is required.
Acetaminophen is a good analgesic and anti-pyretic agent.
Acetaminophen does not effect the production of pro-inflammatory compounds and therefore can not reduce inflammation.
As such, they are beneficial to athletes only as a pain reliever.
Because acetaminophen does not inhibit platelet aggregation, it does not prevent vascular clotting so it provides no protection to heart patients as aspirin does.
Acetaminophen has fewer side effects than aspirin. However, there are damaging affects on the liver. Acetaminophen should therefore be avoided by heavy drinkers.
