Acetaminophen, also known as paracetamol, is a widely used analgesic (pain reliever) and antipyretic (fever reducer). Acetaminophen is the name used in the United States and Japan, while paracetamol is approved in a number of other international locations, while Tylenol is the most common brand name for the product.
This medicine may be used to treat inflammatory pain, it is not typically classified as a nonsteroidal anti-inflammatory drug or "NSAID", because of its weak anti-inflammatory ability.
Generally safe at recommended doses, even small overdoses can be fatal, but may be less toxic when used chronically at suggested doses.
While there have been announcements of healthy adults taking as much as 4,000mg per day with little evidence of toxicity, this is not a suggested dosage, as abnormal liver function may result.
Paracetamol was first marketed in the United States as far back as 1950, and Children's Tylenol in 1955, and it has been available without prescription since 1959.

My Personal Experience
Though commonly available, I find that I personally respond better to Ibuprofen than Acetaminophen, even in doses of 500mg or 1000mg, and I have also mentioned that I do not do well on Naproxen either.
I don't know why, but it just doesn't seem to do as well on my stomach as anything else, and perhaps more importantly, it doesn't fix the problem - that is to say, i still have a headache.
