Paracetamol: Uses, Advantages, and Disadvantages
Introduction
• Paracetamol, also known as acetaminophen, is one of the most widely used over-the-counter (OTC) medications worldwide. It is a popular pain reliever (analgesic) and fever reducer (antipyretic), prescribed for various conditions such as headaches, fever, arthritis, colds, and mild body pain.
• Unlike other pain relievers such as aspirin or ibuprofen, paracetamol is generally considered safer for the stomach and suitable for children, pregnant women, and older adults when taken at recommended doses. However, misuse or overdose of paracetamol can cause serious liver damage and other health complications.
• This article explores the uses, advantages, disadvantages, precautions, and FAQs about paracetamol to help you understand its safe and effective use.
What is Paracetamol?

Paracetamol works by blocking chemical messengers (prostaglandins) in the brain that cause pain and fever. It does not reduce inflammation significantly, which makes it different from NSAIDs (non-steroidal anti-inflammatory drugs) like ibuprofen.
