Paracetamol is used to treat conditions like headaches, muscle aches, arthritis, backaches, toothaches, colds, and fevers by relieving pain but not reducing inflammation or swelling. It should not be taken by those allergic to it or with liver disease or a history of alcoholism. Seeking emergency help is necessary if symptoms of overdose like diarrhea, increased sweating, loss of appetite, nausea or vomiting, or stomach cramps or pain occur while taking paracetamol.
