I agree Wits, The only pain killer worth taking is Paracetamol (INN) (IPA: /ˌpærəˈsiːtəmɒl, -ˈsɛtə-/) or acetaminophen (USAN) is a widely-used analgesic and antipyretic. Derived from coal tar, it is the active metabolite of phenacetin, but unlike phenacetin, paracetamol has not been shown to be carcinogenic in any way. 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) to be used, thereby minimizing overall side-effects. It is also used in combination with opioid analgesics.

It is a major ingredient in numerous cold and flu medications. It is considered safe for human use at recommended doses; however, acute overdose can cause potentially fatal liver damage. The risk is heightened by the use of alcohol. The number of accidental self-poisonings and suicides from paracetamol 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.
