What is Paracetamol?

Paracetamol is a pain reliever, somewhat like aspirin.

WIKIPEDIA provides a very specific answer as follows:
Paracetamol (INN) (IPA: /ˌpærəˈsiːtəmɒl, -ˈsɛtə-/) or
acetaminophen (USAN), is the active metabolite of phenacetin, a so-called coal tar analgesic. Unlike phenacetin, paracetamol has not been shown to be carcinogenic in any way. It has analgesic and antipyretic properties, but, unlike aspirin, it is not a very effective anti-inflammatory agent. It is well tolerated, lacks many of the side-effects of aspirin, and is available over-the-counter, so it is commonly used for the relief of fever, headaches, and other minor aches and pains.

Paracetamol is also useful in the management of more severe pain, where it allows lower dosages of additional non-steroidal anti-inflammatory drugs (NSAIDs) or opioid analgesics to be used, thereby minimizing overall side-effects. It is a major ingredient in numerous cold and flu medications, including
Tylenol and Panadol, among others. It is considered safe for human use at recommended doses; however, acute overdose can cause fatal liver damage often heightened with use of alcohol, and the number of accidental self-poisonings and suicides has grown in recent years. The words
acetaminophen and paracetamol come from the chemical names for the compound: para -acetylaminophenol and para -acetylaminophenol. (The brand name Tylenol also derives from this name: para -acetylaminophenol.) In some contexts, it is shortened to
APAP, for N-acetyl-para-
aminophenol. In the United States, we use the term acetaminopen, commonly known by the brand name TYLENOL. Paracetamol = acetaminophen. It is a pain reliever and antipyretic. A common brand name is Tylenol.
